Abstract
Background and purpose Hair loss is a prevalent problem affecting millions of people worldwide, necessitating innovative and efficient regrowth approaches. Nanostructured lipid carriers (NLCs) have become a hopeful option for transporting bioactive substances to hair follicles because of their compatibility with the body and capability to improve drug absorption. Review approach Recently, surface modification techniques have been used to enhance hair regeneration by improving the customization of NLCs. These techniques involve applying polymers, incorporating targeting molecules, and modifying the surface charge. Key results The conversation focuses on how these techniques enhance stability, compatibility with the body, and precise delivery to hair follicles within NLCs. Moreover, it explains how surface-modified NLCs can improve the bioavailability of hair growth-promoting agents like minoxidil and finasteride. Furthermore, information on how surface-modified NLCs interact with hair follicles is given, uncovering their possible uses in treating hair loss conditions. Conclusion This review discusses the potential of altering the surface of NLCs to customize them for enhanced hair growth. It offers important information for upcoming studies on hair growth.

[PMID: 38800357 PMCID: PMC11122274 DOI: 10.2147/ccid.s462294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Accepted: 05/04/2024] [Indexed: 05/29/2024]
Abstract
Autophagy is recognized as a crucial regulatory process, instrumental in the removal of senescent, dysfunctional, and damaged cells. Within the autophagic process, lysosomal digestion plays a critical role in the elimination of impaired organelles, thus preserving fundamental cellular metabolic functions and various biological processes. Mitophagy, a targeted autophagic process that specifically focuses on mitochondria, is essential for sustaining cellular health and energy balance. Therefore, a deep comprehension of the operational mechanisms and implications of autophagy and mitophagy is vital for disease prevention and treatment. In this context, we examine the role of autophagy and mitophagy during hair follicle cycles, closely scrutinizing their potential association with hair loss. We also conduct a thorough review of the regulatory mechanisms behind autophagy and mitophagy, highlighting their interaction with hair follicle stem cells and dermal papilla cells. In conclusion, we investigate the potential of manipulating autophagy and mitophagy pathways to develop innovative therapeutic strategies for hair loss.

Abstract
JAK-STAT signalling pathway inhibitors have emerged as promising therapeutic agents for the treatment of hair loss. Among different JAK isoforms, JAK3 has become an ideal target for drug discovery because it only regulates a narrow spectrum of γc cytokines. Here, we report the discovery of MJ04, a novel and highly selective 3-pyrimidinylazaindole based JAK3 inhibitor, as a potential hair growth promoter with an IC50 of 2.03 nM. During in vivo efficacy assays, topical application of MJ04 on DHT-challenged AGA and athymic nude mice resulted in early onset of hair regrowth. Furthermore, MJ04 significantly promoted the growth of human hair follicles under ex-vivo conditions. MJ04 exhibited a reasonably good pharmacokinetic profile and demonstrated a favourable safety profile under in vivo and in vitro conditions. Taken together, we report MJ04 as a highly potent and selective JAK3 inhibitor that exhibits overall properties suitable for topical drug development and advancement to human clinical trials.

[PMID: 38628276 PMCID: PMC11016946 DOI: 10.5114/hpr/177730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/05/2023] [Accepted: 12/28/2023] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND Alopecia is an autoimmune condition that results in hair loss, mainly from the scalp. There are three specific types of autoimmune alopecia: alopecia areata (AA; small patches of hair loss), alopecia totalis (AT; total hair loss from the scalp) and alopecia universalis (AU; total hair loss from the scalp and body). Whilst research has explored the experiences of White women living with alopecia, there is a lack of research exploring the impact of alopecia on women in the Black community. The current study aimed to explore Black women's experience of living with autoimmune types of alopecia with a focus on the cultural importance of hair within the Black community and the impact of social support. PARTICIPANTS AND PROCEDURE Seven Black women (age range: 37-68 years; mean age: 51 years) were recruited purposively through alopecia support group organisations and social media to participate in a semi-structured interview; four participants were diagnosed with AA, two participants were diagnosed with AU, and one participant was diagnosed with AT. One-to-one interviews were conducted online, and interpretative phenomenological analysis was used to guide data collection and analysis. RESULTS Participants discussed the significance of hair specifically within the Black community and the complex relationship between psychological wellbeing, coping and seeking support. CONCLUSIONS This novel area, specific to Black women's psychological experience of alopecia, acknowledges the influence of cultural and ethnic differences. The findings suggest that proactive awareness from health professionals and social support groups are needed due to the nuances of Black women's alopecia experience to provide better support and to enhance the quality of life for Black women to manage their alopecia.

[PMID: 38181279 PMCID: PMC10766245 DOI: 10.1097/md.0000000000036803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 12/06/2023] [Indexed: 01/07/2024] Open
Abstract
Telogen effluvium (TE) is a common cause of hair loss characterized by excessive resting hair shedding. Thyroid dysfunction is one of the possible causes of TE. On the other hand, the link between thyroid disorder and TE is still being debated. The aim of this retrospective is to investigate the link between thyroid dysfunction and TE. This retrospective study included 500 female patients with TE who had thyroid function testing between January 2012 and December 2022. Patients were eligible if they had a confirmed TE diagnosis and thyroid function tests within 3 months of being diagnosed with TE. The thyroid function of the participants was classified as euthyroid, hypothyroidism, or hyperthyroidism. The severity of hair loss was determined using the severity of alopecia tool (SALT) score. The study included 500 TE females, 248 of whom were euthyroid, 150 had hypothyroidism, and 102 had hyperthyroidism. The hypothyroid group had a significantly higher mean SALT score than the other 2 groups. Furthermore, patients in the hypothyroid group had a higher proportion of severe hair loss. The mean SALT score did not differ significantly between groups with normal thyroid function and those with hyperthyroidism. A common cause of TE is thyroid dysfunction, particularly hypothyroidism. Patients with hypothyroidism have more severe hair loss than those with normal thyroid function or hyperthyroidism. To effectively identify and manage such cases, thyroid function testing should be included in the diagnostic workup of patients with TE.

Abstract
BACKGROUND Nowadays, the majority of the population suffers from the problem of hair loss. It leads to disturbed mental health, lower self-confidence, and a lot more problems. A lot of the hair loss therapies available are not reliable and lead to recurrence and side effects after some time. Cannabinoids (CBD) have recently become quite popular for their benefits against hair loss. CBD oil preparations have been used both internally and externally for oral and topical use, respectively. Due to the presence of the endocannabinoid system (ECS) in the body, which naturally targets CB1 and CB2 receptors, the control of hair fall is possible. CBD is used topically for hair loss, whereas it is administered orally for the treatment and management of a medical condition, i.e., alopecia. AIM/OBJECTIVE The present review aimed to provide an in-depth study on hair loss and its management using CBD and its associated mechanisms. METHODS Electronic databases, such as ScienceDirect, Google Scholar, PubMed, Wiley, Springer, and Scopus, were thoroughly searched for information about how CBD is used, how it works, and what role it plays in treating alopecia and hair loss. RESULTS This review has highlighted the use of CBD-based hair loss therapy, and described various types of hair loss and their treatments. This review also details the phytocannabinoids and the potential mechanisms of CBD's activity against hair loss and alopecia. CONCLUSION The data obtained from the literature regarding CBD and hair loss provide a scientific basis for CBD use in alopecia. Additionally, a more precise and comprehensive study concerning CBD needs to be carried out at the pre-clinical and clinical levels.

Abstract
Introduction Many cases of telogen effluvium (TE), acute hair shedding, following coronavirus disease 2019 (COVID-19) were reported during the pandemic. Methodology We conducted a cross-sectional study to assess the relationship between COVID-19 and TE in Saudi Arabia. Self-administered online questionnaires were distributed online between March and September 2022 in Saudi Arabia. A multivariate logistic regression model was used to determine risk factors associated with TE post-COVID-19 (significance at P < 0.05). Results Of the 703 responders, 392 were included in the study. 59.70% (n = 234) recognized hair shedding during or after COVID-19. The time taken to realize hair shedding (3 or 6 months) and the duration varied (3, 6, >6 months). The risk factors significantly related to TE post-COVID-19 were: female sex (P < 0.001, odds ratio [OR] = 2.98), COVID-19 antiviral treatment (P = 0.032, OR = 3.02), and TE history (P = 0.001, OR = 3.78). Conclusion Healthcare providers and physicians should be aware of the relationship between TE and COVID-19, to easily recognize, treat, and improve their patients' outcomes).

Abstract
Objectives To assess the effectiveness of adipocyte-derived mesenchymal stem cells-conditioned media (ADSC-CM) formulation in telogen effluvium patients. Methods A retrospective cohort study was conducted at a dermatology clinic in Jeddah, Saudi Arabia. The study included 50 consecutive patients aged 20-70 years, who were diagnosed with telogen effluvium. All patients received five monthly sessions of the same commercial ADSC-CM formulation, using a standardized application protocol. Pre- and post-intervention changes in trichometry parameters were analyzed. Results There was a significant increase in mean hair density (up to 29.01 hair/cm2; effect size 0.7-1.0), cumulative hair thickness (up to 2.67 units; effect size 0.7-1.4), and the number of follicular hair units (up to 19.96%; effect size 1.0-1.3) in all scalp regions (p < 0.001), associated with a decrease in mean trichometry-derived Sinclair scale by 0.8-1.3 (p < 0.001). Positive outcomes were observed in 70%-92% of the patients depending on the parameter and scalp region. There was no impact of the patient's age on ADSC-CM efficacy. Conclusion ADSC-CM was successfully applied as a new treatment option for patients with telogen effluvium. These findings provide another therapeutic and research area for dermatologists to optimize the management of telogen effluvium and reduce its impact on patients.

Abstract
This study aimed to investigate the efficacy of naringenin (NAR) in reducing hair loss. Twenty-four adult Wistar Albino mice, weighing between 25-35 g and aged 6-7 weeks, were used in this research. The dorsal hair of these mice was meticulously clipped and stained subsequently. The mice were randomly divided into four groups (n=6 for each group): (1) negative control group, treated with absolute ethanol alcohol as the vehicle (2) minoxidil (5%) treated group; (3) 0.5% naringenin treated group, and (4) naringenin plus minoxidil treated group. The treatment groups had significantly higher total antioxidant capacity in tissue levels and increased serum levels of vascular endothelial growth factor compared to the control group. No significant differences were observed in keratinocyte growth factor tissue levels between the treatment and control groups. However, the medication significantly increased hair growth, hair follicle diameter expansion, and hair follicle quantity compared to the control group. The finding suggests that the antioxidant and anti-inflammatory properties of NAR significantly reduced hair loss in adult male mice.

Abstract
INTRODUCTION Countless individuals experience negative emotions as hair loss pattern affects their self-esteem and well-being. Rosuvastatin calcium (Ca-RUV) was reported to stimulate the growth of the hair in the applied area, hence, it was selected as a potential hair loss treatment drug. SIGNIFICANCE This study aims to develop and optimize (Ca-RUV) loaded squarticles (SQRs) and assess their ability to deliver and release Ca-RUV in the hair follicle for the promotion of hair growth. METHODS A response surface design was utilized to study the effect of varying Pluronic® F68 (PF68) and the percentage of liquid lipids within the core of the SQRs and the effects of particle size, entrapment efficiency, and drug released percentage after 24 h (%Q24) were assessed. The optimized formula was subjected to DSC, XRD, and in-vivo evaluation in rats. RESULTS SQRs stabilized by 0.8% PF68 and contained 37.5% liquid lipids showed an acceptable particle size (250 nm), drug entrapment efficiency (75%), and %Q24 (100%). The in-vivo studies illustrated the ability of the formula to regrow hair in animals after 10 days due to the elevation of the vascular endothelial growth factor (VEGF) and insulin-like growth factor 1 (IGF-1) to their normal values and by 9% and 54%, respectively, relative to standard therapy minoxidil (5%). CONCLUSION Thus, it can be concluded that the optimized formula of Ca-RUV loaded SQRs showed superior in-vivo results in the promotion of hair growth in a shorter period relative to the marketed product. Therefore, the formula can offer a viable option for the treatment of hair loss.

Abstract
Androgenetic alopecia (AGA), also known as male pattern hair loss (MPHL) or female pattern hair loss (FPHL), is the most common form of alopecia worldwide, and arises from an excessive response to androgens. AGA presents itself in a characteristic distribution unique to both sexes. Despite its prevalence, AGA can be quite challenging to treat. The condition is chronic in nature and stems from an interplay of genetic and environmental factors. There are only two US Food and Drug Administration (FDA)-approved drugs for the condition: topical minoxidil and oral finasteride. However, numerous non-FDA-approved treatments have been shown to be effective in treating AGA in various studies. Some of these treatments are relatively new and still to be explored, thus emphasizing the need for an updated review of the literature. In this comprehensive review, we discuss the evaluation of AGA and the mechanisms of action, costs, efficacies, and safety profiles of existing, alternative, and upcoming therapeutics for this widespread condition.

Abstract
N-Methylformamide (NMF) is a widely used chemical (CAS No.: 123-39-7) in several industries and its usage is continuously increasing. However, studies for NMF have been focused on hepatotoxicity from now. Its toxicity profile has not yet been established owing to limited toxicity data. Therefore, we evaluated systemic toxicity via NMF inhalation. We exposed 0, 30, 100, and 300 ppm NMF to Fischer 344 rats for 6 h/day, 5 days a week for 2 weeks. Clinical signs, body weights, food consumption, hematologic parameters, serum chemistry measurements, organ weights, necropsy, and histopathology were performed. Two females exposed to 300 ppm NMF died during exposure period. Decrease of food consumption and body weight in both sexes exposed to 300 ppm in females exposed to 100 ppm were noted during exposure period. Increased RBC and HGB were noted in females exposed to 300 ppm. A decrease in the levels of ALP and K and increase in the levels of TCHO and Na were observed in both sexes exposed to 300 and 100 ppm. Increased levels of ALT, AST, BUN and decreased levels of TP, ALB, Ca were observed in females exposed to 300 and 100 ppm. The relative liver weight was elevated in both sexes exposed to 300 and 100 ppm NMF. Hypertrophy in the liver and submandibular glands and nasal cavity injuries were noted in both sexes exposed to 300 and 100 ppm NMF. Tubular basophilia of the kidneys were noted in females exposed to 300 ppm NMF. We revealed that NMF affect several organs including the kidneys not only the liver and NMF-related toxicity is predominant in female rats. These results could contribute to the development of NMF toxicity profile and may help in developing strategies for the control of occupational environmental hazards related to NMF.

Abstract
Early and accurate detection of scalp hair loss is imperative to provide timely and effective treatment plans to halt further progression and save medical costs. Many techniques have been developed leveraging deep learning to automate the hair loss detection process. However, the accuracy and robustness of assessing hair loss severity still remain a challenge and barrier for transitioning such a technique into practice. The presented work proposes an efficient and accurate algorithm to classify hair follicles and estimate hair loss severity, which was implemented and validated using a multitask deep learning method via a Mask R-CNN framework. A microscopic image of the scalp was resized, augmented, then processed through pre-trained ResNet models for feature extraction. The key features considered in this study concerning hair loss severity include the number of hair follicles, the thickness of the hair, and the number of hairs in each hair follicle. Based on these key features, labeling of hair follicles (healthy, normal, and severe) were performed on the images collected from 10 men in varying stages of hair loss. More specifically, Mask R-CNN was applied for instance segmentation of the hair follicle region and to classify the hair follicle state into three categories, following the labeling convention (healthy, normal and severe). Based on the state of each hair follicle captured from a single image, an estimation of hair loss severity was determined for that particular region of the scalp, namely local hair loss severity index (P), and by combining P of multiple images taken and processed from different parts of the scalp, we constructed the hair loss severity estimation (Pavg) and visualized in a heatmap to illustrate the overall hair loss type and condition. The proposed hair follicle classification and hair loss severity estimation using Mask R-CNN demonstrated a more efficient and accurate algorithm compared to other methods previously used, enhancing the classification accuracy by 4 to 15%. This performance supports its potential for use in clinical settings to enhance the accuracy and efficiency of current hair loss diagnosis and prognosis techniques.

Abstract
Background Number of reports linked Telogen effluvium to coronavirus disease 2019 (COVID-19) infection. However, data about Telogen effluvium after COVID-19 vaccination are limited. Objectives To estimate prevalence of Telogen effluvium among those who received COVID-19 vaccination. Methods A cross-sectional study was performed during July 2021. Adults who received one of recognized COVID-19 vaccine irrespective of previous COVID-19 infection were asked to fill a questionnaire. Results The majority of participants were females (90.3%). The most common age group was between 21 and 30 years (51.9%). Out of 991 participants who were included in the current analysis, 670 (67.6%) reported post-vaccination hair fall. The probable causes of post-vaccination hair fall were vaccine-related in 185 (27.6%) participants, other causes in 326 (48.7%) participants, and unclear in 326 (48.7%) participants. Post-vaccination hair fall was significantly higher among females compared with males (68.5% versus 57.9%, P = 0.036), those who did not suffer compared with those who suffered from hair fall before vaccination (72.1% versus 63.4%, P = 0.003), and those who did not report compared with those who reported preexisting conditions that might be related to hair fall (74.5% versus 57.3%, P < 0.001). Conclusion We are reporting a high prevalence of post-vaccination hair fall, which affected approximately two-thirds of participants who received COVID-19 vaccines. Only 28% of these participants were apparently vaccine related. The role of COVID-19 infection and stress caused by infection and vaccine cannot be excluded. Primary care physician and dermatologist need to consider the possibility of COVID-19 vaccine as a potential cause of hair loss.

Abstract
Dermal papilla cells (DPCs) are an important element of the hair follicle (HF) niche, widely used as an in vitro model to study hair growth-related research. These cells are usually grown in 2D culture, but this system did not show efficient therapeutic effects on HF regeneration and growth, and key differences were observed between cell activity in vitro and in vivo. Recent studies have showed that DPCs grown in 3D hanging spheroids are more morphologically akin to an intact DP microenvironment. In this current study, global gene molecular analysis showed that the 3D model highly affected cell adhesion molecules and hair growth-related pathways. Furthermore, we compared the expression of signalling molecules and metabolism-associated proteins of DPCs treated with minoxidil (an FDA-approved drug for hair loss treatment) and 3,4,5-tri-O-caffeoylquinic acid (TCQA) (recently found to induce hair growth in vitro and in vivo) in 3D spheroid hanging drops and a 2D monolayer using DNA microarray analysis. Further validations by determining the gene and protein expressions of key signature molecules showed the suitability of this 3D system for enhancing the DPC activity of the hair growth-promoting agents minoxidil and TCQA.

Abstract
Background: The earliest cases of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China, in December 2019. Since the declaration as a pandemic on 11 March 2020, further dermatological conditions continue to be documented. We herein present a novel literature review of dermatological manifestations associated with the Coronavirus Disease 2019 (COVID-19) pandemic. To date, this literature review is the first broad-spectrum examination that analyzes a range of dermatological manifestations related to the COVID-19 pandemic: infection, vaccinations, personal protective equipment (PPE), and psychosocial factors. Methods: A detailed literature search was conducted using key terms for cutaneous manifestations associated with the scope of this review. The search retrieved 2199 articles. Results: The COVID-19 pandemic has triggered a significant range of dermatologic sequela. Etiologies of lesions continue to be investigated. Proposed mechanisms include inflammatory response to spike protein, vitamin D deficiency, ACE2 receptor activation, androgen levels, and increased psychological stress. One prominent mechanism describes viral spike protein invasion into the dermis by binding to the angiotensin-converting enzyme 2 (ACE-2) receptors in keratinocytes, with a secondary immunological response. Conclusions: Dermatologists play an integral role in the proper diagnosis and treatment of COVID-related lesions. Early treatment regimens and timely prophylaxis have been shown to safely reduce infection-related dermatological sequelae. Additional investigations and data collection can reduce disease burden and improve overall prognosis.

Abstract
Alopecia areata (AA) is a chronic, multifactorial, polygenic, and heterogeneous disorder affecting growing hair follicles in susceptible individuals, which results in a non-scarring and reversible hair loss with a highly unpredictable course. Despite very considerable research effort, the nature of the precipitating factor(s) responsible for initiating AA in any given hair follicle remains unclear, due largely to significant gaps in our knowledge of the precise sequence of the etiopathogenic events in this dermatosis. However, disease-related changes in the immune-competence of the lower growing hair follicle, together with an active immune response (humoral and cellular) to hair follicle-associated antigens, are key associated phenomena. Confirmation of the hair follicle antigen(s) implicated in AA disease onset has remained stubbornly elusive. While it may be considered somewhat philosophical by some, it is also unclear whether immune-mediated hair loss in AA results from a) an ectopic (i.e., in an abnormal location) immune response to native (unmodified) self-antigens expressed by the healthy hair follicle, b) a normal immune response against modified self-antigens (or neoantigens), or c) a normal immune response against self-antigens (modified/non-modified) that were not previously visible to the immune system (because they were conformationally-hidden or sequestered) but become exposed and presentable in an MHC-I/-II molecule-restricted manner. While some candidate hair follicle antigen target(s) in AA are beginning to emerge, with a potential role for trichohyalin, it is not yet clear whether this represents the initial and immunodominant antigenic focus in AA or is simply one of an expanding repertoire of exposed hair follicle tissue damage-associated antigens that are secondary to the disease. Confirmation of autoantigen identity is essential for our understanding of AA etiopathogenesis, and consequently for developing a more informed therapeutic strategy. Major strides have been made in autoantigen discovery in other autoimmune conditions. In particular, some of these conditions may provide insights into how post-translational modifications (e.g., citrullination, deamidation, etc.) of hair follicle-restricted proteins may increase their antigenicity and so help drive the anti-hair follicle immune attack in AA.

Abstract
The world continues to contend with successive waves of coronavirus disease 2019 (COVID-19), fueled by the emergence of viral variants. At the same time, persistent, prolonged and often debilitating sequelae are increasingly recognized in convalescent individuals, named 'post-COVID-19 syndrome' or 'long-haul COVID'. Clinical symptomatology includes fatigue, malaise, dyspnea, defects in memory and concentration and a variety of neuropsychiatric syndromes as the major manifestations, and several organ systems can be involved. The underlying pathophysiological mechanisms are poorly understood at present. This Review details organ-specific sequelae of post-COVID-19 syndromes and examines the underlying pathophysiological mechanisms available so far, elaborating on persistent inflammation, induced autoimmunity and putative viral reservoirs. Finally, we propose diagnostic strategies to better understand this heterogeneous disorder that continues to afflict millions of people worldwide.

Abstract
Herein, we report a remarkable case of post-coronavirus disease 2019 (COVID-19) diffuse alopecia that gradually improved and recovered, and the hair volume returned approximately to the pre-infection level, seven months after the patient's first diagnosis of COVID-19. Approximately 20% of patients with COVID-19 develop alopecia a few months after the acute infection phase. Telogen effluvium is the major type of COVID-19 sequela secondary to physical or psychological distress. It is reversible and is expected to improve without any treatment, and it can be addressed by explaining to the patients their conditions, sharing medical information, and eliminating psychophysical stress by managing systemic complications.

Abstract
Diffuse alopecia (DA) is a disease characterized by a diffuse hair loss associated with alterations in physiological hair cycle due to an exposure of hair follicles to various endogenous and exogenous factors. The disease is mainly caused by alterations in the cyclicity of hair follicle phases anagen, telogen and catagen. Pathogenetic therapy for DA is based on the initiation and lengthening of the anagen phase, in particular, via inhibition of catagen. Given a high prevalence of DA following a new coronavirus infection (COVID-19), the search for an effective medicine for the SARS-CoV-2 virus-associated DA is extremely important. The use of drugs derived from natural products can have a beneficial effect on the disease following COVID-19. The study was aimed to assess the efficacy of the combination of Selencin (homeopathic drug) and Selencin Peptide Active (peptide lotion) for the treatment of DA associated with prior coronavirus infection (COVID-19). A total of 34 patients with a confirmed diagnosis of telogen/anagen DA, who noted the relationship between DA and a new coronavirus infection, were treated with both systemic (pills) and topical (peptide lotion) Selencin for 2 months. The study showed a high efficacy of the treatment, i.e., a significant reduction in hair loss, as well as restoration of their structure and increase in volume. Also, after 2 and 4 months of treatment, there was a normalization of dermatoscopic picture of the scalp and an improvement in the special tests (PULL test). Thus, the use of the combined drug Selencin for SARS-CoV-2 virus-associated DA has a pronounced therapeutic effect. The drug can be used as the main treatment for this disease if it associated with COVID-19.

Abstract
ZusammenfassungAutologes plättchenreiches Plasma wird aufgrund seiner wundheilenden Eigenschaften vielfach angewandt u. a. in Orthopädie, Chirurgie und Dermatologie. Zunehmend stellt plättchenreiches Plasma außerdem bei bestimmten Formen der Alopezie eine interessante neue Behandlungsoption dar, sei es als alleinige Therapie oder auch als Adjuvans im Rahmen einer Haartransplantation. Kontrollierte klinische Studien an kleineren Patientengruppen zeigten vielfach positive Ergebnisse, größere Studien stehen bislang noch aus. Die Wirkung auf das Haarwachstum wird sehr wahrscheinlich über die in plättchenreichem Plasma enthaltenen Wachstumsfaktoren und Zytokine vermittelt.

Abstract
Background: There is no clear-cut evidence in the existing medical literature of an association between iron deficiency and nonscarring alopecia. Objective: The objective of the study was to conduct a systematic review of the medical literature on the prevalence of iron deficiency in women with nonscarring alopecia and compare their ferritin levels with those of women without this condition. Methods: The electronic databases PubMed, Scopus, and Web of Science were searched between June 15, 2019, and July 24, 2019. Studies that evaluated the prevalence of iron deficiency in women with nonscarring alopecia and/or compared ferritin levels in women with and without this condition were entered into the meta-analysis. Thirty-six of 928 identified studies entered the systematic meta-analysis. The meta-analysis was performed using the random-effects method. Results: The overall number of participants was 10,029. The prevalence of ferritin levels from 10 to 15 ng/dL and below was 21% (12; 29). Women with nonscarring alopecia had lower ferritin values at MD = −18.51 ng/dL (−25.85; −11.16, p < 0.01). Conclusion: Women with hair loss can benefit from higher ferritin levels.

Abstract
With a practice dedicated to hair restoration and hair loss management, the authors have seen a large number of patients presenting with increased hair fall in the last 18 months. Hair fall after a stressfull event such as infections with febrile episodes is known. However, the latent period between the infective episode and hair fall has been shorter after COVID-19 infection than before. This review attempts to look at various pathways responsible for hair fall and if this differs from the conventional hair fall seen after any infection. It also tries to understand if the infection with the SARS-CoV-2 virus has a direct impact on the hair follicle leading to hair fall.

Abstract
The aim of the present study was to estimate the prevalence of telogen effluvium (TE) and to evaluate the efficacy of vitamin D in the treatment of this problem in women belonging to various cities of south Punjab, Pakistan. In the present study, 40 adult women suffering from the problem of TE were included. Each woman was treated with oral vitamin D3 (200,000 IU) therapy fortnightly and a total of 6 doses were given to each patient. After 15 d of the last dose, the condition of patients was assessed clinically. The mean age of female patients was 32.2±1.5 y, 42.5% of the patients between 21-30 y of age were found to be more frequently affected with TE compared to 35% females of 31-40 y of age. Results showed significant improvement in hair growth in young (r=0.457 p<0.003) women and in those, which do not use sunscreen (r=-0.331 p<0.037) but commonly utilize milk or milk protein (r=-0.311 p<0.051). Vitamin D3 therapy resulted in the improvement of the condition in 82.5% (p<0.001) patients of TE. The use of oral vitamin D3 (200,000 IU, fortnightly) for 3 mo resulted in significant improvement in hair regrowth in the patient of TE. Results showed improvement in hair growth in young women those do not use sunscreen but commonly utilize milk or milk protein.

Abstract
Background Acute telogen effluvium is a non-scaring hair loss, usually occurs 3 months after the stressful event that causes hair shedding, and lasts up to 6 months. It can be associated with post COVID-19 infection. Objective To study the possible effects of COVID-19 on the hair growth cycle and the relationship between COVID-19 and acute telogen effluvium. Patients and methods This is an observational cross-sectional study that had been conducted during the period from September 2020 to March 2021 years. Thirty-nine patients with post COVID-19 hair loss are confirmed by polymerase chain reaction (PCR) or antibody testing. Hair pull test was carried out to confirm the diagnosis and severity of telogen effluvium. Results Thirty-nine patients were evaluated; their ages ranged from 22 to 67 years with a mean and SD of 41.3 ± 11.6 years with 36 (92.3%) females and 3 (7.69%) males. All patients with a diagnosis of ATE were enrolled in this study and had a laboratory-confirmed diagnosis of prior SARS-CoV-2 infection; 15 (38.46%) patients reported mild symptoms, 24 (61.53%) patients presented with moderate disease, and no patient required hospitalization. They all experienced excessive hair loss within 2–3 months after infection. Pull tests were strongly positive (> 10–50% with a mean of 35% of pulled hair away from scalp). Conclusion COVID-19 infection is now a frequent and a common cause of acute telogen effluvium. Hence, clinicians should be aware about the relation between this infection and this pattern of hair loss. Drugs that have been used for the treatment of COVID-19 were excluded as a cause of acute telogen effluvium.

Abstract
Background. Diffuse alopecia (DA) is a pathological hair loss associated with damage to the hair follicle, usually associated with a trigger factor. An important role in the development of this condition is played by the violation of the cyclicity of the phases of the hair follicle anagen, telogen and catagen. The basis of pathogenetic therapy for DA is the induction and prolongation of the anagen stage (including through inhibition of catagen). The use of medicines based on natural ingredients can get a positive effect on the course of the disease.
Aim. To evaluate the effectiveness of complex therapy with Selencin in the treatment of DA.
Materials and methods. The study was conducted on 80 patients with the proved diagnosis of DA (telogenic/anagenic). The treatment was carried out with Selencin in tablet form and external form (peptide lotion) for 2 months. The effectiveness of the drug was assessed 2 and 4 months after the start of treatment (immediately after the end of the course and 2 months later).
Results. The high clinical efficacy of the therapy has been shown in a significant reduction in hair loss, as well as restoration of their structure and increase in volume. Also, after 2 and 4 months from the start of treatment, there was a normalization of the dermatoscopic picture of the scalp and an improvement in the results of special tests (PULL test).
Conclusion. The use of a combination of drugs Selencin in the management of DA has a pronounced therapeutic effect. The drugs can be used as the primary treatment for this disease.

Abstract
Bariatric surgery is a potential modality for the management of obesity. Bariatric patients may experience skin disorders and hair loss postoperatively. A 24-year-old woman with polycystic ovarian syndrome-associated obesity successfully underwent bariatric surgery. Within seven weeks after surgery, she developed diffuse and progressive hair loss, characteristic of telogen effluvium. Alopecia following bariatric surgery may be acute in onset, occurring within the first three months and often associated with telogen effluvium. In addition, bariatric surgery postoperative hair loss may be the result of nutritional deficiencies; in this setting, it is often chronic in onset, occurring six months after surgery. Also, hair loss in bariatric patients may be multifactorial in etiology. We introduced an acronym to facilitate the description of patients who experience bariatric surgery-induced telogen effluvium: Bar SITE.

Abstract
Although mostly seen in the scalp, alopecia can occur in any hair- bearing site of the body. In spite of various modern treatments, total cost, efficacy, safety and drug dependency have caused a global willing towards natural remedies. The aim of this chapter is to focus on medicinal plants mentioned in Canon of Avicenna, one of the most primary medicinal books, for the treatment of alopecia. Databases like PubMed, Scopus and Google Scholar were searched for plants mentioned in Canon for managing alopecia to find studies on their clinical efficacy or mechanisms, which may have attributed to the treatment of alopecia. 25 plants belonging to 16 families have been mentioned in Canon. Most of them have a history of use in ethno-medicine and some are used in hair growth products nowadays. Investigating literatures has shown that anti- inflammatory and immunomodulatory properties are the proposed mechanisms for the treatment of some types of alopecia. Islamic traditional medicine can give new insights for development of multiple natural treatment, which their use in human have been tested for thousands of years. By confirming their efficacy and safety, traditional herbal remedies are appropriate alternatives for chemicals mainly used for alopecia.

Abstract
The relationship between disorders of iron metabolism and alopecia, in particular telogen hair loss (THL), remains poorly understood and requires further research.
Goal. To assess changes in the dynamics of growth and hair condition in women with an iron deficiency state during systemic therapy with iron supplements in combination with and without physiotherapy.
Methods. An open-label, randomized, comparative interventional study with a duration of 6 months included 26 female aged 19 to 54 years (38.8 8.9 years) with complaints of hair loss, changes in their structure, dryness and / or hair brittleness; with preserved menstrual cycle and mild iron deficiency anemia (IDA, Hb 101120 g/l). Trichoscopy and phototrichogram were performed with processing of the results in the TrichoScienceProv1.1 program. The changes in the dynamics of hair growth and condition were assessed against the background of the use of iron supplements in combination with physiotherapy and without physiotherapy. Pulsed alternating sinusoidal current of high frequency, high voltage and low strength was chosen as a physiotherapeutic method for the treatment of THL.
Results. Against the background of the therapy, an increase in the Hb level (p 0.001) and a positive dynamics of trichological parameters in all patients were noted, the severity of which was higher when the therapy with iron supplements was combined with physiotherapy.
Conclusion. Our findings confirm that the complex treatment of patients with telogen alopecia on the background of an iron deficiency state may achieve positive dynamics of trichological indicators.

Abstract
This literature review was designed to investigate the effects of the microneedle therapy system (MTS) on alopecia in experimental, and clinical studies. The MTS is acupuncture needling therapy delivered by a roller. A literature review of studies published before May 2020 was conducted using 9 online databases, and a total of 13 studies (4 in vivo studies and 9 clinical trials) were included. Most studies showed that the MTS was effective when used in combination with other treatments. In vivo studies reported an increased level of hair growth factors following treatment. Typically, 1.5 mm needles were used in the MTS treatment and photographic evaluation (by either camera or microscope) was reported in most studies. Oriental medicine research included 2 in vivo studies, which reported positive effects when combined with the MTS. There were no reported severe side effects. the MTS might be safe and has a drug delivery effect. Further studies need to be conducted regarding the frequency and needle length depending on the type of alopecia using Oriental and Western medicine.

Abstract
BACKGROUND Telogen effluvium is the most common form of non-scarring alopecia characterized by diffuse hair loss. Ischemia-modified albumin is a marker of oxidative stress and inflammation. OBJECTIVE The aim of this study was to compare the levels of ischemia-modified albumin of telogen effluvium patients with healthy controls. METHODS Ninety-one patients diagnosed with telogen effluvium and 35 healthy volunteers were included in the study. Serum ischemia-modified albumin level was determined by a fast-colorimetric method, and albumin cobalt binding test. The results were evaluated statistically. RESULTS There was no statistically significant difference between the serum albumin values of patient and control groups (p=0.739). Serum ischemia-modified albumin values were significantly higher in the patients with telogen effluvium than healthy controls (p<0.001). STUDY LIMITATIONS Body mass index values of the patient and control groups could not be calculated. CONCLUSIONS To the best of the authors' knowledge, this is the first clinical study to investigate the role of oxidative stress in the pathogenesis of telogen effluvium using ischemia-modified albumin as a biomarker. Based on the results of the present study, it can be considered that oxidative stress plays an important role in the pathogenesis of telogen effluvium. There is a need for further studies to support the results of this study, to demonstrate the possible effects of oxidative stress, and to investigate the other oxidative stress markers in the pathogenesis of telogen effluvium.

Integral Roles of Specific Proteoglycans in Hair Growth and Hair Loss: Mechanisms behind the Bioactivity of Proteoglycan Replacement Therapy with Nourkrin® with Marilex® in Pattern Hair Loss and Telogen Effluvium. Dermatol Res Pract 2020; 2020:8125081. [PMID: 32425997 PMCID: PMC7222612 DOI: 10.1155/2020/8125081] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Accepted: 02/01/2020] [Indexed: 11/30/2022] Open
Abstract
Follicular proteoglycans are key players with structural, functional, and regulatory roles in the growth and cycling behaviour of the hair follicles. The expression pattern of specific proteoglycans is strongly correlated with follicular phase transitions, which further affirms their functional involvement. Research shows that bioactive proteoglycans, e.g., versican and decorin, can actively trigger follicular phase shift by their anagen-inducing, anagen-maintaining, and immunoregulatory properties. This emerging insight has led to the recognition of “dysregulated proteoglycan metabolism” as a plausible causal or mediating pathology in hair growth disorders in both men and women. In support of this, declined expression of proteoglycans has been reported in cases of anagen shortening and follicular miniaturisation. To facilitate scientific communication, we propose designating this pathology “follicular hypoglycania (FHG),” which results from an impaired ability of follicular cells to replenish and maintain a minimum relative concentration of key proteoglycans during anagen. Lasting FHG may advance to structural decay, called proteoglycan follicular atrophy (PFA). This process is suggested to be an integral pathogenetic factor in pattern hair loss (PHL) and telogen effluvium (TE). To address FHG and PFA, a proteoglycan replacement therapy (PRT) program using oral administration of a marine-derived extract (Nourkrin® with Marilex®, produced by Pharma Medico Aps, Aarhus, Denmark) containing specific proteoglycans has been developed. In clinical studies, this treatment significantly reduced hair fall, promoted hair growth, and improved quality of life in patients with male- and female-pattern hair loss. Accordingly, PRT (using Nourkrin® with Marilex®) can be recommended as an add-on treatment or monotherapy in patients with PHL and TE.

Abstract
BACKGROUND: Biotin is popular in hair loss treatment supplements, although the frequency of its deficiency in patients with hair loss has not been established. OBJECTIVES: This work sought to assess the serum levels of biotin in patients with telogen effluvium. METHODS: This case-control study included 60 patients with telogen effluvium and 20 control subjects. Subjects who were on biotin therapy three months prior to the study and those reporting other causes of hair loss were excluded. The scalp of each patient was clinically and dermoscopically examined. Serum biotin levels were measured using enzyme-linked immunosorbent assay kits. RESULTS: Serum levels of biotin were optimal in patients and control groups with no significant difference between the groups. Insignificantly lower biotin levels in elderly patients, smokers, athletes, those with a history of recurrent infections, and women who were pregnant and/or lactating were observed. There was also an insignificant positive correlation between the serum level of biotin and patient age and an insignificant negative correlation between disease duration and patient body mass index. Serum biotin has a weak specificity and sensitivity in differentiating between cases and control subjects or between acute and chronic telogen effluvium. CONCLUSION: There was no significant difference in serum biotin levels between cases and controls or between those with acute or chronic telogen effluvium.

Abstract
Background Telogen effluvium (TE) is a form of alopecia characterized by diffuse hair shedding. Vitamin D receptor (VDR) plays a role in hair cycle regulation as it is expressed in follicular keratinocytes and dermal papilla cells. Purpose To investigate the association between Cdx1 and Taq1 VDR gene polymorphisms and chronic TE. Methods Thirty female patients with chronic TE were selected and 30 healthy, age- and sex-matched volunteers were included as a control group. Detection of VDR gene polymorphisms Taq1 and Cdx1 was done by real-time polymerase chain reaction. Results Regarding Taq 1, CC genotype was present in 30% of cases versus 3.3% of controls. TC genotype was present in 33.3% of cases and 36.7% of controls. CC genotype was significantly associated with cases (P=0.01). It increases the risk of chronic TE by 14.7 folds. C allele was significantly associated with patient group (P=0.004). It increases the risk of disease occurrence by 3.1 folds. Regarding Cdx1, AA genotype was present in 6.7% of cases versus 3.3% of controls. GA genotype was present in approximately 30% of cases and 6.7% of controls. GA genotype was significantly associated with cases (P=0.03). It increases the risk of chronic TE by 6.3 folds. A allele was significantly associated with patient group (P=0.007). It increases the risk of disease occurrence by 3.8 folds. Limitations The main limitation is the small number of cases due to the time and financial constraints. Only chronic TE was analyzed, therefore, other types should be investigated in the following studies. Conclusion After exposure to primary physical or mental stressor, hair follicles are stimulated to enter prematurely into telogen and shed out. In individuals with Taq1 and Cdx1 polymorphisms, the disease persists as a result of prevention of new anagen growth and inhibition of hair follicle stem cell proliferation.

Abstract
OBJECTIVE The aim of the present study was to determine the incidence of alopecia and related factors and the health-related quality of life (HRQoL) in high-school students in rural areas of Eskisehir. This was a cross-sectional study. METHODS The study was performed between March 2, 2015 and April 30, 2015. A total of 1662 (74.9%) students were included in the study. The questionnaire performed for the purpose and consisted of four sections was filled out by the students themselves under supervision. The HRQoL was evaluated by Short Form-36 (SF-36). Students' hair and scalps were examined by a dermatologist. The acquired data were analyzed by SPSS 20 statistical package program. Chi-square test, Mann-Whitney U test, and logistic regression analyses were used for statistical analyses. A p value ≤0.05 was accepted as statistically significant. RESULTS In the present study, the incidence of alopecia was found to be 37.4% (n=622). Alopecia was more frequently seen in male students who have complaints about their scalps and those with a fatty scalp. In the study group, students with alopecia had poor HRQoL in general health perception, vitality, and mental health of SF-36. CONCLUSION There is a need to provide early diagnosis and treatment to decrease the incidence of alopecia and to improve the quality of life. Health education studies must be performed to increase the awareness of students about alopecia. Integrating hair and scalp examination into school health screening studies, steering the students who have alopecia to the dermatologists, and suggesting students who have fatty scalp regular hair washing will be appropriate.

Abstract
Alopecia, a frequently reported problem, severely impacts the quality of life of patients and is often associated with loss of confidence and low self-esteem. Several conditions such as telogen effluvium (TE), anagen effluvium, diffuse type of alopecia areata, female pattern hair loss, hair shaft abnormalities, loose anagen hair syndrome, and congenital atrichia or hypotrichosis are associated with hair loss. The actual prevalence rate of TE is not reported since most cases are subclinical in nature. Further, since women get more distressed by hair fall and promptly seek treatment, they tend to be over-represented. However, both genders can suffer from this condition if triggering factors are present. This consensus paper was developed by taking into account opinions of renowned experts in the field and is hoped to serve as an evidence-based platform for selecting efficacious and safe therapy for patients with TE. This review presents a synopsis of the key opinions of experts on all aspects of treatment and effective management of this condition.

Abstract
Hair disorders are common in clinical practice and depending upon social and ethnic norms, it can cause significant psychosocial distress. Hair growth, cycling and density are regulated by many endogenous factors, mainly circulating hormones. Thus, diseases affecting the endocrine system can cause varied changes in physiological hair growth and cycling. Diagnosis and treatment of these disorders require a multidisciplinary approach involving a dermatologist, gynecologist and an endocrinologist. In this review, we briefly discuss the influence of hormones on the hair cycle and hair changes in various endocrine disorders.

Abstract
BACKGROUND Despite a multitude of studies, etiology of primary chronic telogen effluvium (TE) remains incompletely understood. Essential heavy metals are associated with beneficial effects in humans as well as in other living organisms. However, they may lead to toxic effects when the exposure exceeds the higher tolerable limits. We wanted to assess the heavy metal and trace element levels in patients with chronic TE. MATERIALS AND METHODS A total of 40 subjects with chronic TE were included in the study, and 30 healthy women served as control. General and dermatological examinations were taken up in all individuals. Those patients with positive hair pull test were evaluated with the help of a trichogram. The presence of >20% telogen hair as documented by trichogram was a requirement for the study inclusion. UNICAM-929 spectrophotometry device was used for determining serum trace element and heavy metal concentrations. RESULTS In spite of an absence of significant differences in terms of average Zn concentration, weight, or height between patients and controls, significant differences were noted for Cd, Fe, Mg, Mn, Pb, Co, and Cu (P <0.05). CONCLUSION Our results suggest that heavy metals may play a causative role in the development of chronic TE. However, contrary to previous reports, zinc did not appear to play an important etiological role, while these patients had elevated serum iron levels.

Abstract
Non-scarring hair loss is a common problem that affects both male and female patients. Since any disturbances in the hair follicle cycle may lead to hair shedding, or alopecia, it is not surprising that the possible role of vitamin D in alopecia was investigated in many studies. Vitamin D has been shown to have many important functions. A growing body of evidence shows that vitamin D and its receptor are responsible for maintaining not only calcium homeostasis but also skin homeostasis. Moreover, vitamin D could also regulate cutaneous innate and adaptive immunity. This paper presents a review of current literature considering the role of vitamin D in alopecia areata, telogen effluvium, and female pattern hair loss. The majority of studies revealed decreased serum 25-hydroxyvitamin D levels in patients with different types of non-scarring alopecia, which could suggest its potential role in the pathogenesis of hair loss. According to the authors, vitamin D supplementation could be a therapeutic option for patients with alopecia areata, female pattern hair loss, or telogen effluvium. However, further studies on a larger group of patients are required.

Abstract
Hair shedding in female patients is a frequent complaint in dermatological, endocrinological, and gynecological consults. Previously, the Sinclair Hair Shedding Scale was developed to assess normal versus excessive hair shedding in female pattern hair loss (FPHL) subjects. However, the prevalence of hair shedding in females not suffering from FPHL is unknown. To gain better understanding of hair shedding in the general population, we recruited 300 subjects visiting a public hospital for conditions other than alopecia. Of the 300 subjects recruited, 263 did not suffer from FPHL. Among those subjects, approximately 40% reported experiencing excessive hair shedding (as defined by the Sinclair Hair Shedding Scale) on hair washing days. In comparison, in our subject population, approximately 60% of subjects with FPHL reported excessive hair shedding on hair washing days. To best of our knowledge, this is the first study to quantify the prevalence of hair shedding in women. While, no treatment currently exists for this condition, we hope that this study would encourage physicians and researchers to address this frequent concern.

Abstract
INTRODUCTION Postpartum telogen effluvium (PPTE) is a commonly described entity, but few studies deal with the real incidence and pathogenesis of this claimed common disease. OBJECTIVE To analyze the objective data published and to define the real incidence of the so-called PPTE. METHOD A retrospective review of the published data was conducted. RESULTS No statistically significant data were found in any of the papers reviewed, which could support the conclusion that the amount of hair shedding between pregnant and postpartum women is different. CONCLUSION PPTE is not a well-defined entity, and the exact incidence is unknown. From our literature review, we could state that the frequency of PPTE is so low and undefined that we dare say that PPTE does not exist.
