Abstract
Background: Androgenetic alopecia, the most common cause of non-scarring hair loss, is a consequence of the gradual miniaturization of the hair follicles. In the majority of male androgenetic alopecia cases, a patient's history and clinical evaluation may be sufficient to establish the diagnosis, while for women, they should be supplemented with trichoscopy. Methods: The PubMed and Scopus databases were used to collate published studies and to analyze the most typical trichoscopic findings in patients diagnosed with androgenetic alopecia. A total of 34 articles were retrieved after exclusion. Results: The most common features identified using trichoscopy included hair diameter variability (94.07% of patients), vellus hairs (66.45%) and the peripilar sign (43.27%). Others, such as the honeycomb pattern, yellow and white dots, were less relevant. Conclusions: We concluded that hair diameter variability, vellus hairs and the peripilar sign represented valuable indicators for the diagnosis of androgenetic alopecia.

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.

Abstract
BACKGROUND The number of clinical trials evaluating platelet-rich plasma (PRP) efficacy in female androgenetic alopecia (F-AGA) has exponentially increased during the last five years. A systematic review focused on this specific field has been performed by assessing the local infiltrations of PRP compared with any control for F-AGA in the selected studies. OBJECTIVES The aim of this study was to evaluate the safety and efficacy of the use of PRP in F-AGA. METHODS The protocol was developed in accordance with the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines. A multistep search of PubMed, MEDLINE, Embase, PreMEDLINE, Ebase, CINAHL, PsycINFO, Clinicaltrials.gov, Scopus database, and Cochrane databases has been performed to identify papers on female pattern hair loss (FPHL) treatment with PRP. Of the 63 articles initially identified, 11 articles focusing on AGA were selected and, consequently, only 5 articles focused exclusively on F-AGA were analyzed. Of this amount, 3 articles were randomized-controlled trials (RCTs), 1 clinical trial, and 1 double-blind placebo-controlled pilot study (DBPCPS). The studies included had to match predetermined criteria according to the PICOS (patients, intervention, comparator, outcomes, and study design) approach. RESULTS Eight percent of the articles selected and analyzed, reported a positive effect of PRP for F-AGA treatment. The information analyzed highlights the positive effects of PRP on F-AGA, without major side effects and thus, it may be considered as a safe and effective alternative procedure to treat hair loss compared with traditional drugs as Minoxidil® and Finasteride®. CONCLUSIONS The use of PRP in F-AGA was safe and effective for F-AGA.

Abstract
Background Androgenetic alopecia is characterized by a progressive miniaturization of hair follicles in a pattern distribution in genetically predisposed individuals. The efficacy of conventional therapies is variable, therefore there is a need for adjuvant and newer treatment modalities to provide faster and better outcomes. Objectives Evaluation of vehiculated through iontopthheo ereffsiicsa icny paantdie tnotlse rwaibtihli tayn odfr ao gceonmebtiicn aeldo tpheecriaap ayn: dp raesfsoorcmiaetded g rteolwogthe nfa ecftfolursvium, to obtain faster hair regrowth. Materials and Methods Treatment was performed between June 2018 and June 2019 on 60 patients with androgenetic alopecia and associated telogen effluvium. Each patient underwent 4 sessions in total, each session was performed every 3 weeks. Global photography and trichoscopy were collected at every session of therapy. All patients filed out a self-assessment questionnaire. Results Results were very promising, with improvement of hair density and thickening of the hair shaft diameter in most of patients seen with both global photography and trichoscopy. All patients were satisfied of the clinical result and reported a complete reduction in hair loss. No serious adverse side effects were reported. Conclusions The use of growth factors associated with iontophoresis technique is a useful treatment for treating and preventing androgenetic alopecia. In addition, in case of associated telogen effluvium, this technique allows for an early stop of hair shedding, especially when cosmetic procedures do not provide satisfactory results in patients.

Abstract
Current medicinal therapies for treating hair loss have shortcomes due to variability and ineffectiveness, noncompliance, and adverse effects. The prevalence of hair loss and its associated negative psychological impact have driven research into regenerative medicine approaches, such as platelet-rich plasma (PRP) and cell-based therapies, in an attempt to find alternative, safe, effective, and reproducible treatments. Current research shows promising results from these therapies; however, more robust trials are needed to confirm the reported efficacies of PRP and cell-based therapies. Moreover, standardization of treatment preparation as well as dose and regimen are needed.

Abstract
Background: female androgenetic alopecia (FAGA) is a common cause of non-scarring alopecia in women, affecting approximately 40% of women by age 50, bearing a significant psychosocial burden on affected patients. Platelet-rich plasma (PRP) has been widely investigated as a potential effective treatment for several dermatological conditions, including male androgenetic alopecia (MAGA). However, few studies have been conducted focusing on the use of PRP in FAGA. The aim of this review was to identify reports that investigated the use of PRP for the treatment of FAGA. Methods: Electronic databases of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to September 2020 have been searched using different combinations of the following terms: “androgenetic alopecia,” “FAGA,” “female pattern hair loss,” “platelet-rich fibrin,” “platelet-rich plasma,” and “PRP”. Results and conclusions: Eight (n = 8) clinical studies consistent with our research were identified. A total of 197 subjects has been enrolled in the included studies. All of them were adult female patients (mean age: 38.9) affected by female pattern hair loss. PRP is a well-tolerated procedure which showed promising results in males-only and mixed populations of AGA patients. PRP showed to produce high levels of satisfaction and improvement in the quality of life in patients affected by FAGA. In the light of this evidence, PRP may be proposed in patients who did not respond or did not tolerate topical minoxidil, as well as in combination with topical and oral treatments.

Abstract
The goal of these recommendations is to provide a framework to practitioners for implementing useful, evidence-based recommendations for the preparation of platelet-rich plasma (PRP) and its use in androgenetic alopecia (AGA). The Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) assigned the task of preparing these recommendations to its taskforce on PRP. A comprehensive literature search was done in the English language on the PRP across multiple databases. The grade of evidence and strength of recommendation were evaluated on the GRADE (Grading of Recommendation, Assessment, Development, and Evaluation) framework. A draft of clinical recommendations was developed on the best available evidence, which was also scrutinized and critically evaluated by the IADVL Academy of Dermatology. Based on the inputs received, the final consensus statement was prepared. A total of 30 articles (meta-analyses, prospective and retrospective studies, reviews [including chapters in books], and case series) were critically evaluated, and the evidence thus gathered was used in the preparation of these recommendations. This expert group recommends use of manual double-spin method for the preparation of PRP for AGA. Minimum three to five sessions of PRP are recommended for AGA with a gap of 1 month between the two sessions. Patients with Grade II to V Norwood Hamilton classification of AGA are the ideal subset for PRP. A total of 5 to 7 mL of PRP and 0.05 to 0.1 mL/cm2 is the recommended dose of PRP for AGA. Activation of PRP is not required when it is used for AGA. About 1 to 1.5 million platelets/μL of platelets in PRP is the recommended platelet concentration in PRP for the treatment of AGA. I-PRF (injectable platelet-rich fibrin) has also been found to be useful in AGA, although further studies are required to establish its role. PRP can also have an adjunctive role in hair transplantation procedures.

Abstract
BACKGROUND Platelet-rich plasma (PRP) is an increasingly popular treatment modality for various dermatologic conditions, but there are limitations in both the published literature and clinician knowledge. OBJECTIVE To create a high-yield, in-depth analysis of PRP in procedural dermatology by reviewing available data on its role in hair restoration, soft-tissue remodeling, resurfacing, and rejuvenation; identifying practice gaps and controversies; and making suggestions for future research that will establish dermatologists as pioneers of regenerative medicine. MATERIALS AND METHODS A two-part systematic review and expert analysis of publications before October 2018. RESULTS AND CONCLUSION Most studies on PRP report favorable outcomes with the strongest level of evidence existing for androgenetic alopecia followed by postprocedure wound healing, scar revision, striae, rejuvenation, and dermal filling. There is a dearth of large randomized controlled trials, considerable heterogeneity in the variables studied, and lack of specificity in the preparatory protocols, which may influence clinical outcomes. Future investigations should use consistent nomenclature, find ideal solution parameters for each cutaneous indication, determine significant outcome metrics, and follow double-blinded, randomized, controlled methodologies. Addressing these deficiencies will take sound scientific inquiry but ultimately has the potential to benefit the authors' specialty greatly.

Abstract
The prevalence of hair loss, its psychological consequences, and historically subpar treatments present a unique challenge to the physician. The current Food and Drug Administration-approved treatments for hair loss are plagued by ineffectiveness, noncompliance, and adverse effects. Recent advances in our understanding of hair physiology have fueled the development of more efficacious, minimally invasive, and safer treatment options for hair restoration including plasma-rich protein and stem cell therapy. Platelet-rich plasma, the autologous preparation of concentrated platelets in plasma, when injected into the scalp of patients with both androgenetic alopecia (AGA) and alopecia areata (AA), has been shown to increase hair count and density. The clinical findings have been supported by histologic evaluation of the scalp skin. These findings have been recapitulated in numerous randomized controlled trials. Stem cell therapy, although newer in its application in hair restoration, has also been effective for treating both AGA and AA. The isolation techniques for stem cells are varied, but regardless have shown promising results in early prospective and retrospective studies.

Abstract
Female androgenetic alopecia (FAGA) is a common cause of non-scarring alopecia in women. The onset may be at any age following puberty and the frequency increases with age. Clinically, it shows a diffuse hair thinning over the central scalp, while the frontal hairline is usually retained. FAGA can have a significant psychological impact, leading to anxiety and depression. For this reason, early diagnosis is very important to stop the progression of the disease. The sex hormonal milieu is the main pathogenetic mechanism studied in FAGA. The role of androgens is not clearly defined and only one-third of women with FAGA show abnormal androgen levels. Endocrinological diseases with hyperandrogenism associated with FAGA comprise polycystic ovarian syndrome (PCOS), hyperprolactinemia, adrenal hyperplasia and, rarely, ovarian and adrenal tumours. Usually the diagnosis of FAGA is made clinically. A complete clinical examination and a blood examination can reveal other signs of hyperandrogenism. Trichoscopy shows the typical hair miniaturization. A scalp biopsy can be useful when the clinical evaluation does not provide a definitive diagnosis or when cicatricial alopecias with hair loss in the distribution of FAGA or alopecia areata are suspected. FAGA is a slowly progressive disease. The goal of therapy is to stop the progression and to induce a cosmetically acceptable hair regrowth. The most important drugs are topical minoxidil and oral anti-androgens. The purpose of this review is to provide an update on FAGA and to create a guideline on diagnosis and management of this frequent hair disease, not always easily recognizable from cicatricial alopecias with a similar distribution.

Abstract
BACKGROUND Platelet-rich plasma (PRP) treatment may encourage hair growth by promoting cellular maturation, differentiation, and proliferation. OBJECTIVE The objective of this study was to evaluate the effectiveness of PRP as a treatment for androgenetic alopecia (AGA). MATERIALS AND METHODS A literature search combined with meta-analysis was used to calculate the overall standardized mean difference (SMD) in hair density in patients treated with PRP injections in comparison with baseline and placebo treatment. Chi squared analysis and Fisher exact test were used to investigate variation in protocols. RESULTS The overall SMD in hair density was 0.58 (95% confidence interval [CI]: 0.35-0.80) and 0.51 (95% CI: 0.23-0.80, p < .0004) in favor of PRP treatment when compared with baseline and placebo treatment, respectively. CONCLUSION Platelet-rich plasma is beneficial in the treatment of AGA. It is recommended that 3 monthly sessions of PRP (once monthly ×3 treatments) be used followed by a 3- to 6-month maintenance period.

Abstract
BACKGROUND AND OBJECTIVES Platelet-rich plasma (PRP) has received growing attention as a valuable therapeutic tool in androgenetic alopecia (AGA). However, knowledge regarding specific effectiveness and satisfaction of PRP for different grades of AGA in male pattern hair loss (MPHL) and female pattern hair loss (FPHL) is missing. This study aims to ascertain and compare the efficacy and safety of PRP treatment for different grades of AGA in males and females over 6 months. METHODS In this study, 51 MPHL patients with Norwood-Hamilton stage II-V and 42 FPHL patients with Ludwig stage I to III were enrolled for 6 monthly sessions of PRP injections. A longitudinal analysis was used to compare the hair density, thickness, and hair pull test over 6 months for MPHL and FPHL through generalized estimating equation (GEE) models. Phototrichograms of scalp inflammation and oil secretion, global photographs and overall patient satisfaction were also assessed. RESULTS Consequently, improvement of hair density, hair thickness, hair pull test, the level of scalp inflammation and oil secretion were observed with statistical significance in all stages for both MPHL and FPHL at 6 months. Noteworthy, lower level of alopecia (Grade II, III in MPHL and Grade I in FPHL) had better response to PRP, and also had a better tendency of increment of hair growth than that of high-grade patients with prolonged treatment. CONCLUSIONS PRP injections, as an efficacious and reliable therapy, can be recommended for Grade II and Grade III in MPHL and Grade I in FPHL.

Abstract
BACKGROUND While dermatologists focus on practices to promote anti-aging, thinning hair that frames a more rejuvenated face can affect age perception and cosmesis. OBJECTIVES To characterize the effects of age-related hair changes on age determination and perceived attractiveness. METHODS A search was conducted for articles on intrinsic and extrinsic aging as it relates to hair. Key studies on the hair aging process and its effects on self-perception, confidence, and anti-aging were reviewed. RESULTS According to several studies, hair density peaks about 27 years of age or earlier and then decreases from the mid-thirties onward. This serves as an opportunity to prevent or treat hair loss in a similar way we treat aging skin. Without optimizing appearance of hair, overall cosmesis to foster self-perception can be curtailed despite multiple efforts to rejuvenate and restore the aging face. CONCLUSION The discrepancy between rejuvenated faces and thinner appearing hair that frames the face highlights the importance of a holistic approach to the anti-aging consultation. To more comprehensively address the aesthetic patient, we need to promote awareness of the onset of these hair changes in order to incorporate prevention and therapeutic strategies to preserve hair to complement overall appearance.

Abstract
As a promising alternative to traditional treatment, platelet-rich plasma (PRP) is being used to encourage hair growth through the release of growth factors and cytokines. In addition to hair restoration, PRP’s multifactorial capabilities can also be used to treat aging skin, facial scarring, and acne. The purpose of this review is to critically examine the success of PRP in the field of dermatology, with specific attention to the role of PRP in hair restoration. Where possible, meta-analyses were used to evaluate the efficacy of PRP. In androgenetic alopecia (AGA) patients, 3 monthly PRP injections (1 session administered every month for 3 months) exhibited greater efficacy over placebo as measured by change in total hair density (hair/cm2) over the treatment period (mean difference: 25.61, 95% CI: 4.45 to 46.77; P = .02). The studies included in the meta-analysis used a half-head design, which may have influenced the results because of the effects PRP can induce. Controlled studies suggest that 2 to 4 sessions of PRP combined with traditional therapies and procedures can help minimize acne scarring and facial burns, improve aesthetic results, and decrease recovery time. However, data for these indications are lacking and are less robust in design. In conclusion, to achieve an improvement in hair restoration in patients with mild AGA, 3 initial monthly PRP injections should be given. Only upon completion of rigorous, randomized, controlled studies can standardized and effective PRP protocols for treating dermatology conditions such as acne scarring, facial burns, and aging skin be determined.
