Abstract
OBJECTIVE To conduct a systematic review and meta-analysis to verify the efficacy of using autologous platelet-rich plasma (PRP) in female pattern alopecia (FPA). BACKGROUND Androgenetic alopecia is the leading cause of hair loss in men andwomen and often impacts self-esteem and quality of life. DATA SOURCES MEDLINE/PubMed, Cochrane Library, ClinicalTrials.gov, and EMBASE up to May 2021. STUDY SELECTION AND DATA EXTRACTION We identified all studies evaluating the effect of PRP in FPA. A narrative synthesis was performed from data on the efficacy of PRP treatment and adverse effects; quantitative results of PRP use compared to control treatment for female androgenetic alopecia (AGA) were synthesized. The outcomes analyzed were terminal density and hair thickness. RESULTS Seven articles were selected for this review. Meta-analysis showed that PRP-based interventions were able to increase terminal hair density compared to control (standardized mean difference (SMD)=2.98, 95% confidence intervals (CIs)=1.10, 4.85), with no significant increase in hair thickness (SMD = 1.16, 95% CI= -0.96, 3.28). During and after treatment, no major side effects were reported by patients or researchers. CONCLUSIONS The use of autologous PRP injections in female AGA seems to be promising, with more consistent results on terminal hair density. However, caution is recommended in the interpretation of these results until they can be replicated in larger and more representative samples. PROSPERO registration number CRD42021257154.

Zari S. Assessment of Occipital Involvement Among a Large Population of Females with Pattern Hair Loss in Saudi Arabia. Clin Cosmet Investig Dermatol 2023; 16:2687-2696. [PMID: 37790906 PMCID: PMC10544099 DOI: 10.2147/ccid.s422283] [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: 06/11/2023] [Accepted: 09/16/2023] [Indexed: 10/05/2023]
Abstract
Background Cumulative evidence suggests the involvement of the occipital region in female pattern hair loss (FPHL). However, most of the studies that have been published so far concerned relatively small samples of patients. Purpose To assess the occipital involvement in FPHL and analyze its correlation with disease severity among a large sample of patients. Patients and Methods A retrospective study involved 1000 adult women with FPHL, between January 2020 and August 2022. Occipital involvement was defined as more than 10% of thin hairs (<0.03 mm). Baseline trichometry parameters in the frontal and occipital regions were analyzed. Results Occipital involvement was observed in 32.4% of the patients. Positive correlations between frontal and occipital regions were observed for all trichometry parameters; the strongest concerned average hair shaft thickness (Pearson's coefficient r=0.708), cumulative hair thickness (r=0.673), and trichometry-derived Sinclair scale (r=0.656). The risk of occipital involvement increased independently with the disease severity in frontal region; however, the disease progression was slower in the occipital compared to frontal region. Conclusion One-third of females in our study with FPHL had occipital involvement. This has a major impact on the methods used to diagnose pattern hair loss in females and their treatment plan including hair restoration surgery.

Abstract
Pattern hair loss can occur in both men and women, and the underlying molecular mechanisms have been continuously studied in recent years. Male androgenetic alopecia (M-AGA), also termed male pattern hair loss, is the most common type of hair loss in men. M-AGA is considered an androgen-dependent trait with a background of genetic predisposition. The interplay between genetic and non-genetic factors leads to the phenotype of follicular miniaturization. Although this similar pattern of phenotypic miniaturization can also be found in female pattern hair loss (FPHL), the corresponding genetic factors in M-AGA do not account for the phenotype in FPHL, indicating that there are different genes contributing to FPHL. Therefore, the role of genetic factors in FPHL is still uncertain. Understanding the genetic mechanism that causes FPHL is crucial for the future development of personalized treatment strategies. This review aims to highlight the differences in the ethnic prevalence and genetic background of FPHL, as well as the current genetic research progress in nutrition, Wnt signaling, and sex hormones related to FPHL.

Abstract
Hair-loss diseases comprise heterogenous conditions with respective pathophysiology and clinicopathological characteristics. Major breakthroughs in hair follicle biology and immunology have led to the elucidation of etiopathogenesis of non-scarring alopecia (e.g., alopecia areata, AA) and cicatricial alopecia (e.g., lichen planopilaris, LPP). High-throughput genetic analyses revealed molecular mechanism underlying the disease susceptibility of hair loss conditions, such as androgenetic alopecia (AGA) and female pattern hair loss (FPHL). Hair loss attracted public interest during the COVID-19 pandemic. The knowledge of hair loss diseases is robustly expanding and thus requires timely updates. In this review, the diagnostic and measurement methodologies applied to hair loss diseases are updated. Of note, novel criteria and classification/scoring systems published in the last decade are reviewed, highlighting their advantages over conventional ones. Emerging diagnostic techniques are itemized with clinical pearls enabling efficient utilization. Recent advances in understanding the etiopathogenesis and management for representative hair diseases, namely AGA, FPHL, AA, and major primary cicatricial alopecia, including LPP, are comprehensively summarized, focusing on causative factors, genetic predisposition, new disease entity, and novel therapeutic options. Lastly, the association between COVID-19 and hair loss is discussed to delineate telogen effluvium as the predominating pathomechanism accounting for this sequela.

Abstract
Female pattern hair loss (FPHL) is the most common form of alopecia in women. FPHL may compromise body image and strongly affect self-esteem, negatively impacting quality of life. Currently, the only Food and Drug Administration (FDA) approved drug for its treatment is topical minoxidil, with a variable response rate. Recently, a few studies in FPHL have pointed out bicalutamide as an emergent selective androgen receptor antagonist with a favorable safety and tolerability profile. This review aimed to summarize and discuss the key information on this new therapy for FPHL. Bicalutamide has no diuretic effect. It does not cross the blood-brain barrier, and it has little effect on serum luteinizing hormone. Additionally, bicalutamide was found to be effective on women presenting with other features of hyperandrogenism such as seborrhea, acne, and hirsutism with mild and well-tolerated adverse effects. Despite the high prevalence and psychosocial impairment, FPHL treatment remains challenging. Therefore, although future prospective, comparative, randomized clinical trials are essential to establish the ideal dose and efficacy of the drug, oral bicalutamide appears to be a promising option to expand the arsenal of FPHL treatment.

Abstract
Female pattern hair loss (FPHL) is a non-scarring alopecia resulting from the progressive conversion of the terminal (t) scalp hair follicles (HFs) into intermediate/miniaturized (i/m) HFs. Although data supporting nutrient deficiency in FPHL HFs are lacking, therapeutic strategies are often associated with nutritional supplementation. Here, we show by metabolic analysis that selected nutrients important for hair growth such as essential amino acids and vitamins are indeed decreased in affected iHFs compared to tHFs in FPHL scalp skin, confirming nutrient insufficiency. iHFs also displayed a more quiescent metabolic phenotype, as indicated by altered metabolite abundance in freshly collected HFs and release/consumption during organ culture of products/substrates of TCA cycle, aerobic glycolysis, and glutaminolysis. Yet, as assessed by exogenous nutrient supplementation ex vivo, nutrient uptake mechanisms are not impaired in affected FPHL iHFs. Moreover, blood vessel density is not diminished in iHFs versus tHFs, despite differences in tHFs from different FPHL scalp locations or versus healthy scalp or changes in the expression of angiogenesis-associated growth factors. Thus, our data reveal that affected iHFs in FPHL display a relative nutrient insufficiency and dormant metabolism, but are still capable of absorbing nutrients, supporting the potential of nutritional supplementation as an adjunct therapy for FPHL.

Lasers Med Sci 2022; 37:2589-2594. [PMID: 35133519 PMCID: PMC9343305 DOI: 10.1007/s10103-022-03520-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 02/02/2022] [Indexed: 11/17/2022]
Abstract
Low-level laser therapy (LLLT) has been a treatment modality by many androgenetic alopecia (AGA) patients in recent years. It remained unclear as to how long the treatment regime should be maintained, and which characteristics of patients should this be recommended. A real-world study was carried out with an FDA-cleared low-level laser helmet for 1383 patients. Ordinal logistic regression analysis with propensity score matching (PSM) was used to investigate the factors related to efficacy assessment. More than 80% of users were between 18 and 40 years old. The median use times were 133 for mild AGA patients and 142 for moderate-to-severe AGA patients, which equated to 38 weeks and 40 weeks, respectively. The overall clinical effectiveness was nearly 80%. PSM analysis revealed that gender (P = 0.002), use period (P = 0.068), scalp conditions with dandruff, rash, and itchy symptoms were associated with the grading of efficacy assessment. Male users (ordinal OR: 1.35, CI: (1.01, 1.79)); use for more than 180 times or use period for 1 year (ordinal OR: 1.40, CI: (1.11, 1.96)); and those with scalp dandruff (ordinal OR: 1.34, CI: (1.01, 1.87)), rash (ordinal OR: 1.47, CI: (1.04, 2.07)), and itchy symptoms (ordinal OR: 1.51, CI: (1.12, 2.03)) had better efficacy assessments. The recommended treatment regime with low-level laser helmet was more than 1 year or 180 use times. Male patients with dandruff, rash, and itchy symptoms in scalps tended to have a better efficacy assessment.

Abstract
Background Female-pattern hair loss (FPHL) is a common disorder affecting women, and FPHL can cause psychological dysfunction and affect the social activities of patients. The disease-causing mechanisms are believed to be similar to those of male androgenetic alopecia (MAGA). Although genome-wide association studies (GWAS) have confirmed susceptibility genes/loci for MAGA, the associations between these genetic loci and FPHL are largely unknown. We investigated the associations between susceptibility loci for MAGA and FPHL in a Chinese Han population; a literature review of susceptibility loci associated with MAGA for FPHL was also performed. Material/Methods Twenty-two previously reported sites were analyzed with the Sequenom iPlex platform, and the genotype statistical analysis consisted of a trend test and conservative accounting. The samples comprised 82 patients diagnosed with FPHL by dermatoscopy and 381 healthy controls from the Chinese Han population. Results No significantly associated variants were found in this FPHL study. The examined 22 tag SNPs in MAGA may not be associated with FPHL. The results of the current study in a Chinese Han population support the previous negative association obtained for a European population. Conclusions This was the first study exploring whether identified MAGA-associated loci confer susceptibility to FPHL in a Chinese Han population, and dermatoscopy was used to improve the diagnostic accuracy. However, there was no evidence of a relationship between susceptibility genes for MAGA and FPHL, and the results indicated that FPHL and MAGA are etiologically separate entities. Therefore, a systematic GWAS approach to FPHL may be required to clarify associated pathophysiological uncertainties.

Abstract
Background Alopecia in women is generally difficult to diagnose clinically. Trichoscopy may help make the correct diagnosis in doubtful cases. Objective The aims of the study were to assess the trichoscopic features of different types of alopecia in women, the reliability of trichoscopy vis-à-vis clinical findings, and the validity of trichoscopy in cases with a doubtful clinical diagnosis. Methods A hospital-based observational, cross-sectional study was carried out on female patients with alopecia. A trichoscopic diagnosis was made and correlated with a clinical diagnosis. The validity of trichoscopy in doubtful cases was evaluated by reporting the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic value. Results On trichoscopy, increased hair diameter diversity > 20%, single-hair follicular unit, vellus hair, peripilar sign, and focal atrichia were commonly seen in female pattern hair loss. In telogen effluvium, there was a scarceness of specific findings. In cicatricial alopecias, loss of follicular ostia, erythema, white macules, blue-gray dots, white dots, tufted hair, and keratotic follicular plugging were observed. A good agreement between trichoscopy and clinical diagnosis was found (Cohen’s Kappa = 0.824; 95% confidence interval, 0.756–0.892). The validity of trichoscopy in doubtful cases was evaluated using the validity parameters, which were high in all alopecias. Limitations Histopathology testing was not done in all patients. Conclusion Trichoscopy helped reach a definitive diagnosis in patients in whom the clinical diagnosis was doubtful. Thus, trichoscopy is a sensitive and specific investigation that can be valuable in women with alopecia.

Abstract
Purpose This study aimed to explore the relationship between serum ferritin levels and telogen effluvium. Patients and Methods A total of 193 telogen effluvium patients and 104 female androgenetic alopecia patients were included. We collected the test result of serum ferritin levels, compared with the results of 183 healthy subjects. Receiver Operator Characteristic curves were generated to assess the potential diagnostic value of serum ferritin in telogen effluvium patients. Results The serum ferritin in telogen effluvium patients were significantly lower than that in the healthy control group (P = 0.000) or female androgenetic alopecia patients (P =0.000). Patients with lower serum ferritin levels got high odds to have telogen effluvium. The areas under the Receiver Operator Characteristic curve of serum ferritin levels were 0.735 and 0.645 for distinguishing telogen effluvium patients from healthy control subjects or female androgenetic alopecia patients. Conclusion Serum ferritin could be a potential biomarker for clinical diagnosis of telogen effluvium.
