J Cosmet Dermatol 2024; 23:1560-1572. [PMID: 38239003 DOI: 10.1111/jocd.16186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/14/2023] [Accepted: 01/05/2024] [Indexed: 04/25/2024]
Abstract
OBJECTIVE To provide dermatologists with more clinical experience in treating androgenetic alopecia, we evaluated the effect and safety of combined microneedling therapy for androgenetic alopecia. METHODS Studies on combined microneedling for hair loss were comprehensively searched by us in PubMed, Excerpta Medica Database, and the Cochrane Library Database. The literature search spanned the period from 2012 to 2022. Inclusion and exclusion criteria were developed, and the literature was screened according to this criteria. The Cochrane Risk of Bias Tool was used to assess the quality of the studies. The researcher applied Revman 5.3 and Stata 15.1 software to analyze the data after extracting information from the data. RESULTS Finally, 13 RCTs involving 696 AGA patients were included to compare the clinical effectiveness and adverse events of combined MN therapy with single MN therapy or single drug therapy for AGA. The results of meta-analysis showed as follows: (1) Hair density and diameter changes: The combined MN group was significantly better than any single treatment group, and the differences were statistically significant (MD = 13.36, 95% CI = [8.55, 18.16], Z = 5.45, p < 0.00001; MD = 18.11, 95% CI = [13.70, 22.52], Z = 8.04, p < 0.00001; MD = 13.36, 95% CI = [8.55, 18.16], Z = 5.45, p < 0.00001; MD = 2.50, 95% CI = [0.99, 4.02], Z = 3.23, p = 0.001); (2) the evaluation of satisfaction for efficacy: The doctor satisfaction rating of the combined MN group was significantly higher than that of any single treatment group, with statistical difference (RR = 2.03, 95% CI = [1.62, 2.53], Z = 6.24, p < 0.00001). The difference between the two groups regarding patients satisfaction was not significant (RR = 3.44, 95% CI = [0.67, 17.59], Z = 1.49, p = 0.14). (3) Safety: There was no statistical difference in the incidence of adverse reactions between combination therapy and monotherapy (RR = 0.83, 95% CI = [0.62, 1.12], Z = 1.22, p = 0.22). CONCLUSION The combined MN group showed statistically significant improvement in hair density and diameter, and good safety compared with monotherapy.

Skin Appendage Disord 2023; 9:397-406. [PMID: 38058547 PMCID: PMC10697753 DOI: 10.1159/000534196] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 09/18/2023] [Indexed: 12/08/2023] Open
Abstract
Background Combination treatments may improve the utility of approved agents for the treatment of pattern hair loss (PHL); however, head-to-head comparisons are lacking. Objective The aim of the study was to compare the efficacy of 5% minoxidil, platelet-rich plasma (PRP), and microneedling across adults with PHL insofar as change in total hair density at 24 weeks. Methods We conducted a literature search in July 2022. Through our Bayesian network meta-analysis, we estimated treatments' surface under the cumulative ranking distribution (SUCRA) values and relative effects - in terms of mean difference (MD). Results Data from 27 trials, totaling 1,110 patients, were extracted. Interventions were ranked based on the probability of inducing hair density improvements: 5% minoxidil plus microneedling (SUCRA = 95.8%), 5% minoxidil plus PRP (SUCRA = 64.7%), 5% minoxidil (SUCRA = 53.9%), PRP (SUCRA = 34.9%), microneedling (SUCRA = 27.8%), and PRP with microneedling (SUCRA = 22.9%). The efficacy of 5% minoxidil plus microneedling in improving total hair density was significantly greater (p < 0.05) than 5% minoxidil monotherapy (MD = 13 hairs/cm2), PRP monotherapy (MD = 16 hairs/cm2), and microneedling monotherapy (MD = 17 hairs/cm2). Conclusion Five percent minoxidil plus microneedling is an effective treatment option for improving hair density at 6 months in adult PHL patients.

Abstract
Androgenetic alopecia (AGA) is the most common cause of hair loss in men and women. Traditionally, topical minoxidil and oral finasteride have been the standard of care yielding mixed results. New treatments such as Low-Level Laser Therapy (LLLT), microneedling, platelet-rich plasma (PRP), and others have been extensively studied in the literature, and the purpose of this review is to provide a comprehensive discussion of the latest treatment methods and their efficacy in treating AGA. Novel therapies such as oral minoxidil, topical finasteride, topical spironolactone, botulinum toxin, and stem cell therapy offer interesting alternatives to standard of care therapies for patients. In this review, we present data from recent studies on the clinical efficacy of these treatments. Furthermore, as new treatments have emerged, clinicians have tested combination therapies to assess whether there may be a synergistic relationship between multiple modalities. While there has been a great increase in the treatments available for AGA, the quality of evidence varies greatly and there is still a great need for randomized double blinded clinical trials to adequately assess the clinical efficacy of some treatments. While PRP and LLLT have demonstrated encouraging results, standardized treatment protocols are needed to adequately inform clinicians on how to use such therapies. Given the abundance of new therapeutic options, clinicians and patients must weigh the benefits and risks of each treatment option for AGA.

Platelet-rich plasma for the treatment of alopecia: a systematic review and meta-analysis. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2023; 21:24-36. [PMID: 34967722 PMCID: PMC9918380 DOI: 10.2450/2021.0216-21] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Accepted: 09/17/2021] [Indexed: 02/12/2023]
Abstract
BACKGROUND The number of articles evaluating the efficacy of platelet-rich plasma (PRP) in androgenetic alopecia (AGA) and alopecia areata (AA) has increased exponentially during the last years. This systematic review and meta-analysis is aimed at evaluating the benefit of PRP in the treatment of alopecia. MATERIAL AND METHODS We searched MEDLINE (through PUBMED), Embase, and CENTRAL for relevant data. Treatment effect was described by mean difference (MD) and risk difference with 95% confidence intervals (CI). The GRADE system was used to assess the certainty of the body of evidence. RESULTS We found 27 controlled trials (1,117 subjects) that met our inclusion criteria: 18 trials (713 subjects) in patients with AGA, and 9 (404 subjects) in patients with AA. Eleven studies had a split head design. There was heterogeneity in types of PRP (e.g., activated and non-activated) and administration schedules. PRP was compared to saline injections (18 studies), local steroid injections (4 studies) and other comparators (5 studies). Most commonly reported outcomes were hair density and hair regrowth. It was not possible to pool all outcome data because of heterogeneity in reporting, and because reporting was often limited to a single study. Compared to saline injections, PRP injections increased hair density over a medium-term follow-up (MD, 25.6 hairs/cm2; 95 % CI: 2.62-48.57), but the evidence was rated as low quality due to inconsistency and risk of bias. In individuals with AA, it is unclear whether PRP injection compared with triamcinolone injection increase the rate of subjects with hair regrowth (very-low quality of evidence due to inconsistency, imprecision, and risk of bias). There were no serious adverse events related to PRP injection or control treatments. CONCLUSIONS There is limited evidence showing benefit of PRP for treatment of alopecia, and most of this evidence is of low quality.

Abstract
BACKGROUND Microneedling refers to a minimally invasive technique that uses multiple fine needles targeted skin epidermis for mechanical stimulation to obtain therapeutic or cosmetic effects. It is suitable for the treatment of a variety of dermatological conditions, including androgenetic alopecia (AGA). OBJECTIVE This article aims to make a comprehensive review of the relevant studies on microneedling for the management of AGA. METHODS Extensive literature search was performed using PubMed, Web of Science, and EBSCO databases. 4 in vivo studies and 25 clinical trials were included according to the inclusion and exclusion criteria. RESULTS The effects of microneedling on AGA was investigated in animal experiments. Several clinical trials, including randomized controlled trials, strengthen the validity of the findings. Microneedling therapy showed some encouraging results with minor complications when used alone or in combination with topical products. CONCLUSIONS Microneedling appears to be a safe and effective therapeutic option for AGA. Larger and more randomized controlled trials regarding the role of microneedling in AGA are strongly recommended to provide more definitive evidence.

Abstract
OBJECTIVE The goal of this study was to assess the perceived efficacy of a standardized nutraceutical to improve hair growth and quality in men and women of various ethnicities with self-perceived hair thinning. METHODS This prospective, single-blind study enrolled healthy men aged 20 to 55 years (n=47) and premenopausal women aged 20 to 45 years (n=51) with self-perceived, mild-to-moderate hair thinning and included African American, Asian, Hispanic Caucasian and Non-Hispanic Caucasian participants. The nutraceutical supplement (Nutrafol® Men or Women Capsules, Nutraceutical Wellness Inc., New York, New York) was taken daily for six months. Subjects were evaluated in the clinic at baseline and Weeks 12 and 24 with two self-assessments at Weeks 4 and 8. Study endpoints were standardized digital imaging and investigator rated assessments. Self-assessment questionnaires rated hair growth, hair satisfaction, and lifestyle factors. RESULTS Investigator ratings for baseline hair growth, coverage, density, and volume were significant at Weeks 12 and 24 for all subjects (for each, p<0.001). These significant improvements were seen in 83.7 percent of men and 79.5 percent of women at Week 24. Results were similar across ethnic subgroups with significant benefit at Weeks 12 and 24 (for each, p<0.05). All subjects reported significant improvements in baseline hair appearance/quality, volume/fullness, scalp coverage, thickness, and shedding at Weeks 4, 8, 12 and 24 (for each, p<0.01). CONCLUSION A standardized nutraceutical supplement improved visible hair growth with less notable shedding based on subjects' and investigators' overall perception of treatment benefit for men and women of various ethnic backgrounds.

Abstract
Introduction Microneedling (MN) is a minimally invasive procedure involving the induction of percutaneous wounds with medical-grade needles. In this literature review, we investigate clinical data on MN for the treatment of hair loss disorders. Methods A literature search was conducted through PubMed up to November 2021 to identify original articles evaluating the use of MN on hair loss disorders. The database was searched using the following keywords: “microneedling,” “micro needling,” “micro needle,” “microneedle,” “needle,” “dermaroller” and “alopecia,” “hair loss,” “alopecia,” “areata,” “cicatricial,” or “effluvium.” Results A total of 22 clinical studies featuring 1127 subjects met our criteria for inclusion. Jadad scores ranged from 1 to 3, with a mean of 2. As an adjunct therapy, MN improved hair parameters across genders and a range of hair loss types, severities, needling devices, needling depths of 0.50–2.50 mm, and session frequencies from once weekly to monthly. Across 17 investigations totaling 911 androgenic alopecia (AGA) subjects, MN improved hair parameters when paired with 5% minoxidil, growth factor solutions, and/or platelet-rich plasma (PRP) topicals, or when introduced to subjects whose hair count changes had plateaued for ≥ 6 months on other treatments. Across four investigations on 201 alopecia areata (AA) subjects, MN improved hair parameters as a standalone therapy versus cryotherapy, as an adjunct to 5-aminolevulinic acid and photodynamic therapy, and equivalently when paired with topical PRP versus carbon dioxide laser therapy with topical PRP. Across 657 subjects receiving MN, no serious adverse events were reported. Conclusions Clinical studies demonstrate generally favorable results for MN as an adjunct therapy for AGA and AA. However, data are of relatively low quality. Significant heterogeneity exists across interventions, comparators, and MN procedures. Large-scale randomized controlled trials are recommended to discern the effects of MN as a standalone and adjunct therapy, determine best practices, and establish long-term safety.

Abstract
BACKGROUND Microneedling is a relatively novel therapeutic modality introduced in the 1990s where small, fine needles are used to create micro punctures in the skin. It is a minimally invasive procedure used for various dermatological conditions, including androgenetic alopecia (AGA). OBJECTIVE AND METHODS We comprehensively summarize the literature regarding microneedling in dermatology. We performed linear multivariable regressions to synthesize evidence from the clinical trials that investigated the efficacy of microneedling for AGA. Studies eligible for quantitative analyses were assessed for evidence quality. RESULTS The exact mechanism of microneedling action is yet to be determined, with theories that include the wound-healing cascade. Microneedling monotherapy significantly increased total hair count more than topical minoxidil 5% (β = 12.29; p < 0.001). The combination treatment of microneedling with topical 5% minoxidil increased total hair count significantly compared to monotherapy with microneedling (β = 7.63, p < 0.05). Increasing the overall treatment duration of microneedling and reducing the frequency of microneedling sessions may positively influence an increase in total hair count. CONCLUSION There are limited studies that investigate microneedling as a monotherapy for hair loss since majority of the trials combine it with other therapies such as topical minoxidil or platelet-rich plasma. While preliminary results look promising, further investigation of microneedling as a monotherapy in larger, randomized controlled trials will help determine its safety and efficacy, and place in treating AGA.
