ABSTRACT

This case series evaluated use of injectable platelet rich fibrin (termed i-PRF+) for the treatment of female pattern hair loss (FPHL). Eleven individuals underwent 3-monthly intradermal injections of i-PRF+ using a mesotherapy gun. The mean number of hair follicles containing hairs per unit area improved at 3- and 6-months follow-up (p < .001), and all participants had a negative hair pull test. Hair volume and thickness, and patient-reported outcome scores also improved at follow-up (p < .001). Adverse effects were minor and self-limited. A series of three i-PRF+ injection sessions were effective for the treatment of FPHL, as shown by improved hair analysis parameters and patient self-assessment scores.

ABSTRACT

While many gene expression studies have focused on male pattern baldness (MPB), few studies have investigated the genetic differences between bald and non-bald hair follicles in female pattern hair loss (FPHL). This study aimed to identify molecular biomarkers associated with FPHL through genetic analysis of paired bald and non-bald hair follicles from 18 FPHL patients, using next-generation sequencing (NGS) techniques. RNA transcriptome analysis was performed to identify differentially expressed genes (DEGs) between bald and non-bald hair follicles in FPHL. The DEGs were validated using real-time PCR, and protein expression was confirmed through immunohistochemistry and western blot analysis. Our findings suggest that HOXB13, SFRP2, PTGDS, CXCR3, SFRP4, SOD3, and DCN are significantly upregulated in bald hair follicles compared to non-bald hair follicles in FPHL. SFRP2 and PTGDS were found to be consistently highly expressed in bald hair follicles in all 18 samples. Additionally, elevated protein levels of SFRP2 and PTGDS were confirmed through western blot and immunohistochemical analysis. Our study identified SFRP2 and PTGDS as potential biomarkers for FPHL and suggests that they may play a role in inducing hair loss in this condition. These findings provide a foundation for further research on the pathogenesis of FPHL and potential therapeutic targets.

ABSTRACT

Female Pattern Hair Loss (FPHL) is a common form of non-scaring hair loss that occurs in adult women. Although several treatments have already been proposed for FPHL, only Topical Minoxidil accumulated an adequate level of evidence. This study aimed to evaluate the therapeutic response of MMP® (intradermal infiltration) of Minoxidil formulation in the frontal-parietal-vertex regions compared with the gold-standard home administration of Minoxidil 5% Capillary Solution. This self-controlled comparative study evaluated 16 FPHL patients, without treatment for at least 6 months, confirmed by trichoscopy with TrichoLAB® software. They received 4 monthly sessions of MMP® with Minoxidil 0,5% on the right side of the scalp (frontal-parietal-vertex areas), followed by occlusion with plastic film for 12 h and prescription of Minoxidil 5% Solution for home use once a day, on both scalp sides, starting 72 h after the procedure. The reassessment trichoscopy was 6 weeks after the last session and they answered a "self-assessment" questionnaire. Treated scalp areas were compared and showed both treatments, in general, were effective, with no difference between them. If they were analyzed separately by treated areas, there were signs of better response in the parietal-vertex regions with treatment by MMP® with Minoxidil, while clinical treatment indicated a better response in the other regions. When patients were divided into more and less advanced cases, a better response in parietal-vertex regions treated by MMP® with Minoxidil in less advanced patients was confirmed. MMP® with Minoxidil showed a better response in the parietal-vertex regions in less advanced FPHL patients. It represents yet another resource to improve quality of life of these suffering patients.

ABSTRACT

BACKGROUND: Hair transplant (HT) is the standard treatment for female pattern hair loss (FPHL), but scalp micropigmentation (SMP) is an alternative. Currently, there are no criteria to help choose between HT and SMP. METHODS: Forty female patients with FPHL who had successfully undergone HT and SMP, were reviewed to identify factors that might help decide between treatments. Hair density (HD) and hair caliber were measured at the part line and mid-occipital region by a Folliscope. The sensitivity and specificity of HT and SMP were determined by area under the curve (AUC) and receiver operating characteristic curve. RESULTS: Patients were divided into HT (n = 23) and SMP (n = 17) groups. The follicular unit density (FUD) (HT: 62.06 ± 4.8551/cm2; SMP: 66.59 ± 3.4971/cm2) and HD (HT: 96.16 ± 16.6954/cm2; SMP: 116.08 ± 17.0520/cm2) were significantly different (p < 0.01) between groups. The AUC for FUD was 77.6% with a cutoff value of 66.83 and 87.0% (1-0.412) sensitivity. The AUC for HD was 82.4% with a cutoff value of 96.17 and 69.6% (1-0.118) sensitivity. CONCLUSIONS: HD was the most important factor when deciding between HT surgery and SMP. SMP is recommended when the HD is ≥104.6 hairs/cm2 and HT surgery is strongly recommended when the HD is ≤96.17 hairs/cm2.

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

BACKGROUND: Female pattern hair loss (FPHL) is the most prevalent type of alopecia among adult women. Presently, topical minoxidil stands as the sole treatment endorsed by the FDA. Addressing cases of FPHL in individuals who develop contact dermatitis in response to minoxidil can pose a challenge for dermatologists. OBJECTIVE: To assess the efficacy and safety of subcutaneous injections of Botulinum Toxin Type A (BTA) in treating FPHL. METHODS: Enrolled outpatients with FPHL who exhibited an allergic reaction to minoxidil solution. Diagnosis of FPHL was established through clinical examination and trichoscopy. Inclusion criteria involved patients with no prior treatment within the last year and without any comorbidities. BTA, specifically 100 units, was mixed with 2 mL of 0.9% normal saline. Twenty injection target sites, spaced 2-3 cm apart, were symmetrically marked on the hairless area of the scalp. A dosage of five units was intradermally injected at each target site. Representative photographs and dermoscopic images of the scalp were captured before and after 3 months of treatment. RESULTS: A total of 10 FPHL, aged between 26 and 40 years, were included. The average age was 30.3 ± 4.64 years, and all patients had a positive family history of Androgenetic Alopecia. The average duration of the disease was 3.70 ± 1.42 years. According to patients' self-assessment, after 1 month of treatment, 10 FPHL patients reported experiencing moderate to marked improvement in symptoms related to scalp oil secretion. Three months later, dermatological assessments showed that three had mild improvement, six had no change, and one had a worsening condition. No adverse effects were observed. CONCLUSIONS: Our study suggests that the effectiveness of BTA for FPHL is limited to 3 months. However, it can be considered for tentative use after effective communication with patients. The long-term efficacy and safety of BTA in treating FPHL require further observation and study.

ABSTRACT

Background: Many studies have associated male androgenetic alopecia with the risk of cardiovascular disorders but very few studies have addressed this association in women with FPHL. Materials and Methods: This was a cross-sectional hospital-based study in which a total of 50 women (18-45 years) were recruited. The objective was to measure carotid intima-media thickness (CIMT) by doppler ultrasound, Body mass index (BMI), waist circumference, lipid profile, fasting blood sugar (FBS), insulin, testosterone, Sex hormone binding globulin (SHBG), hs-CRP, ESR and fibrinogen, in pre-menopausal women having FPHL and to correlate these parameters with severity of FPHL. The prevalence of Metabolic syndrome (MetS) and Insulin resistance were evaluated. Results: Metabolic syndrome and insulin resistance were found in 12 (24%) and 17 (34%) cases respectively. Hypercholesterolemia, elevated LDL levels and hypertriglyceridemia, low HDL levels and hyperinsulinemia were found in 11 (22%), 31 (62%), 9 (18%), 17 (34%) and 7 (14%) cases respectively. 8 (16%) cases were diabetics. Elevated ESR, increased fibrinogen levels and elevated hs-CRP were found in 43 (86%), 10 (20%) and 21 (42%) cases respectively. CIMT was found to be within its normal range. Correlation of CIMT, anthropometric indices (BMI and WC), biochemical markers (serum cholesterol, triglycerides, FBS, and fibrinogen), and presence of metabolic syndrome with severity of FPHL in terms of Ludwig grade was found to be statistically significant. Conclusions: The determination of metabolic syndrome, insulin resistance and acute phase reactants such as hs-CRP and fibrinogen may be useful screening methods to detect increased cardiovascular risk in women with FPHL.

ABSTRACT

INTRODUCTION: Androgenetic alopecia (AGA) is a prevalent, multifactorial form of hair loss involving complex aetiological factors, such as altered androgen regulation and energy metabolism. Existing treatments offer limited success, thus highlighting the need for advanced, personalised therapeutic strategies. This study focuses on correlating the genetic mechanisms of AGA with molecular targets involved in the response to current treatment modalities. METHODS: An anonymised database including 26,607 patients was subjected to analysis. The dataset included information on patients' genotypes in 26 single nucleotide polymorphisms (SNPs), specifically, and diagnosed AGA grades, representing a broad range of ethnic backgrounds. RESULTS: In our sample, 64.6% of males and 35.4% of females were diagnosed with female pattern hair loss. This distribution aligns well with prior studies, thus validating the representativeness of our dataset. AGA grading was classified using the Hamilton-Norwood and Ludwig scales, although no association was found to the grade of the disease. SNP association analysis revealed eight SNPs, namely rs13283456 (PTGES2), rs523349 (SRD5A2), rs1800012 (COL1A1), rs4343 (ACE), rs10782665 (PTGFR), rs533116 (PTGDR2), rs12724719 (CRABP2) and rs545659 (PTGDR2), to be statistically significant with a p-value below 0.05. CONCLUSIONS: The study establishes a preliminary association between eight specific SNPs and AGA. These genetic markers offer insights into the variability of therapeutic responses, thus underlining the importance of personalised treatment approaches. Our findings show the potential for more targeted research to understand these SNPs' and further roles in AGA pathophysiology and in modulating treatment response.

ABSTRACT

INTRODUCTION: Treating alopecia can be challenging. The available treatments are topical minoxidil, low-dose oral minoxidil (LDOM), and 5-α reductase inhibitors like finasteride and dutasteride. Only topical minoxidil and finasteride 1 mg daily are FDA-approved, while the rest are used off-label. Recent research has suggested that oral minoxidil may be a safe and effective treatment for both female androgenetic alopecia (female AGA) and male androgenetic alopecia (male AGA). AREAS COVERED: In this review, we explore the pharmacokinetics, mechanism of action, safety, and efficacy of oral minoxidil. Additionally, we discuss its effectiveness compared to other treatments available for female AGA and male AGA. EXPERT OPINION: LDOM has demonstrated a favorable efficacy and safety profile in several trials. Subsequently, its use for the treatment of male AGA and female AGA is increasing. However, its use remains off-label, and through increased usage, we will get a better idea of the best dosage and monitoring guidelines. LDOM has also been used with some effectiveness in other forms of hair loss.

ABSTRACT

OBJECTIVES: To investigate the effectiveness and safety of combination of 655 nm low level laser helmet device with topical 2 % minoxidil solution at FPHL in Chinese population. MATERIALS AND METHODS: Randomized, parallel, controlled, single-blind clinical trial was conducted. FPHL subjects were randomly allocated into 2 % minoxidil group and combination group. The 2 % minoxidil group received 1 ml topical 2 % minoxidil solution twice daily for 24 weeks. The combination group received 1 ml topical 2 % minoxidil solution twice daily together with 20 min 655 nm low-level laser helmet once every other day for 24 weeks. Hair parameters in two scalp areas including midscalp and vertex were evaluated at baseline, 12th week and 24th week. RESULTS: In midscalp area, the combination group showed a lower increase in intermediate hair percentage than 2 % minoxidil group, which was statistically significant. Besides, the combination group had statistically significant increase than 2 % minoxidil group in mean hair diameter. Reported relative adverse events included slightly hair loss (27.8 %), desquamation (19.0 %), pruritus (15.2 %), seborrhea (2.5 %) and hypertrichosis (2.5 %). CONCLUSION: In our trial, LLLT was demonstrated as a useful supplementary treatment for FPHL and the combination with 2 % minoxidil accomplished better improvement in intermediate hair enlargement and hair diameter of midscalp for FPHL.

ABSTRACT

BACKGROUND: Minoxidil and the 5-alpha reductase inhibitors (5-ARIs), specifically, dutasteride and finasteride, are usually used to treat pattern hair loss (PHL), but evidence on the relative effectiveness of these drugs is far less for women than men. AIMS: We performed an age-adjusted network meta-analysis (NMA) to determine the comparative efficacy of monotherapy with the three agents-in any dosage and administrative route-on PHL in adult women. METHODS: The peer-reviewed literature was systematically reviewed to obtain data for our NMA. The outcome measure for our NMA was "change in total hair density." We referred to "regimen" as an "agent and its dosage;" our Bayesian NMA estimated regimens' surface under the cumulative ranking curve (SUCRA) values and pairwise relative effects. RESULTS: Our NMA used data from 13 trials-across which the following 10 regimens were identified (in decreasing order of SUCRA): 5 mg/day finasteride for 24 weeks (SUCRA = 95.7%), 5% topical minoxidil solution twice daily for 24 weeks (SUCRA = 89.5%), 1 mg/day minoxidil for 24 weeks (SUCRA = 78.1%), 5% topical minoxidil foam 1 half capful/day for 24 weeks (SUCRA = 66.5%), 3% topical minoxidil solution 1 mL twice daily for 24 weeks (SUCRA = 45.1%), 2% topical minoxidil solution 1 mL twice daily for 24 weeks (SUCRA = 44.6%), 5% topical minoxidil solution 1 mL/day for 24 weeks (SUCRA = 41.7%), 0.25 mg/day minoxidil for 24 weeks (SUCRA = 35.5%), 1.25 mg/day finasteride for 24 weeks (SUCRA = 24.8%) and 1 mg/day finasteride for 24 weeks (SUCRA = 4.3%). CONCLUSION: Our findings can improve clinical guidelines and help dermatologists manage female PHL more optimally with the available options.

ABSTRACT

INTRODUCTION: Non-scarring alopecia mainly includes androgenetic alopecia (AGA), female pattern hair loss (FPHL), alopecia areata (AA), telogen effluvium (TE), anagen effluvium (AE) and so on. Many studies had investigated the serum 25-hydroxyvitamin D level and vitamin D deficiency of patients with these diseases, but opinions varied, and no conclusion was reached. METHODS: Relevant articles were retrieved through PubMed, Web of Science, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI) and other databases. Serum 25-hydroxyvitamin D [25(OH) D] levels and vitamin D deficiency were used as our primary outcome. The odds ratio (OR) and the standardized mean difference (SMD) with 95% confidence interval were both examined for vitamin D deficiency and levels. RESULTS: Our meta-analysis had included a total of 3374 non-scarring alopecia patients and 7296 healthy controls from 23 studies through the inclusion criteria and exclusion criteria. We found non-scarring alopecia had decreased serum 25(OH)D level (WMD -7.29; 95% CI -9.21, -5.38) and increased vitamin D deficiency incidence (OR 3.11 95% CI 2.29, 4.22), compared with healthy controls. This meta-analysis chose to conduct random-effect model and subgroup analysis, because of the high heterogeneity (serum 25(OH)D level: I2 = 95%, vitamin D deficiency: I2 = 0%). CONCLUSION: Patients with non-scarring alopecia (including AA, FPHL, AGA and TE) have insufficient serum level of 25(OH)D and increased incidence of vitamin D deficiency. Vitamin D supplementation and monitoring for vitamin D deficiency may be helpful in treating non-scarring alopecia.

ABSTRACT

BACKGROUND: Autologous cell-based therapy using dermal sheath cup (DSC) cells was reported as a new treatment for male and female pattern hair loss. However, the mechanisms underlying its action remain unclear. OBJECTIVE: We investigated the mechanisms underlying the efficacy of DSC cells in cell-based therapy. METHODS: We conducted multivariate analysis to categorize individuals based on treatment response as responders and non-responders. The differentially expressed genes in DSC cells from the two groups were evaluated using bulk transcriptome, quantitative polymerase chain reaction, and single-cell transcriptome analyses. We performed live cell imaging combined with immunostaining to characterize the DSC subpopulation associated with responders. RESULTS: We identified nine and three genes as high efficacy (HE) and low efficacy (LE) marker genes, respectively. The HE subpopulations were enriched for cell migration-related genes in single-cell analysis. In contrast, the LE subpopulation was enriched for basement membrane and vasculature-related genes. Moreover, DSC cells in culture were immunocytochemically and morphologically heterogeneous, expressing characteristic factors. Furthermore, live cell imaging showed that DSC cells expressing integrin subunit alpha 6 (ITGA6), an HE subpopulation gene, had markedly higher mobility than those expressing the LE subpopulation genes collagen type IV or CD36. CONCLUSIONS: ITGA6-positive DSC cells, with superior migratory activity, may contribute to cell-based therapy by promoting cell migration into nearby hair follicles.

ABSTRACT

INTRODUCTION: Androgenic alopecia (AGA) is the most common cause of hair loss in women, affecting their quality of life. The present study was conducted with the aim of comparing the combined effect of topical minoxidil and oral spironolactone with the combined effect of topical minoxidil and oral finasteride in women with AGA, female and male hair loss patterns. METHOD: This clinical study was performed on 60 women suffering from AGA. The patients were divided into two groups receiving spironolactone 100 mg/day and finasteride 5 mg/day. In addition, a 2% minoxidil solution was used in all patients in addition to treatment with finasteride or spironolactone. At 2 months after initiation and at the end of treatment, patients were evaluated using the Ludwig/Norwood-Hamilton scale and the degree of physician and patient satisfaction. RESULTS: After 2 months, hair density, hair thickness, and hair loss had improved in both groups; however, statistically, there was no significant difference between the two groups with respect to these parameters (p > 0.05). After 4 months, a significant difference was found between the two groups in terms of treatment response (physician satisfaction), hair density, and hair loss severity. So that, the drugs used were ineffective in 6.7% of cases in the minoxidil-spironolactone group and in 16.7% of cases in the minoxidil-finasteride group. In addition, 43.3% of cases in the minoxidil-spironolactone group and 53% in the minoxidil-finasteride group responded well to treatment. The treatment effect was excellent in 56.7% and 0% of the mentioned groups, respectively, and the mentioned difference was statistically significant (p: 0.01). The response to treatment in female pattern hair loss (FPHL) was not statistically significant (p: 0.52), but there was a significant difference in the response to both treatments in male pattern hair loss (MPHL; p: 0.007). In terms of patient satisfaction, minoxidil-spironolactone treatment was significantly better than minoxidil-finasteride regarding hair density and severity of hair loss (p: 0.01). Finally, in terms of treatment complications, the patients in two groups did not have any serious adverse effects. CONCLUSION: The combination of minoxidil and spironolactone could be considered a more effective treatment than the combination of minoxidil and finasteride in women with AGA, FPHL, and MPHL.

ABSTRACT

It is important to understand that each layer of facial tissue, from the underlying facial skeleton to the overlying skin, undergoes significant changes during the aging process. Bony support is lost along the mandible and maxilla and the orbital aperture widens. Superficial and deep fat pads undergo volume loss and migration and the overlying skin begins to reveal signs of both intrinsic aging with skin laxity and fine rhytids as well as extrinsic aging in the form of coarse, deeper rhytids and dyspigmentation.

ABSTRACT

Procedural management, including fractionated laser therapy, has been increasingly investigated for the management of androgenetic alopecia (AGA). However, no comprehensive resources exist detailing the efficacy of fractionated laser therapies used for the treatment of AGA. A systematic review investigating fractionated laser use for AGA was performed, separated into each distinct fractionated laser modality. A meta-analysis was performed to examine improvement in hair counts and hair shaft diameter. Fourteen studies were included for systematic review, which identified the use of erbium-glass, thulium, erbium-ytrrium:aluminum garnet (YAG), and carbon dioxide (CO2) fractionated laser for the treatment of AGA. In the meta-analysis, fractionated laser combination therapy showed significant improvement in hair shaft diameter (2.51, 95% CI 2.37-2.65, I2 = 90.54). Fractionated laser monotherapy alone significantly improved hair shaft diameter (2.28 95% CI 2.03-2.52, I2 = 91.20%). This effect was durable on subgroup analysis for both erbium-glass (2.36 95% CI 2.01-2.71, I2 = 92.05%) and thulium (1.61 95% CI 1.08-2.15, I2 = < 0.00%). There was no improvement in hair shaft count for any laser modality. Erbium-glass laser is an effective modality as either monotherapy or combination with topical/injectable therapies to improve hair shaft diameter in AGA.

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

Background: Female pattern hair loss (FPHL) is known to present with characteristic pathological conditions, including reduced overall hair density. Female hormones affect hair condition; however, the detailed mechanism is unknown. Furthermore, research on the topic is complicated by the fact that senescent alopecia often occurs concurrently with FPHL. Therefore, we investigated the effect of estradiol, a female hormone, on hair growth by eliminating aging factors and objectively evaluating hair changes caused by female hormone replacement therapy (HRT). Objective: This study was conducted to elucidate the mechanism through which female hormones exert their effects on hair. Methods: The study included 11 female patients undergoing HRT who were evaluated before initiating HRT, 3 months after initiating HRT, and 6 months after initiating HRT. The thinning hair score, hair density, telogen hair rate, telogen plucking strength, hair growth rate, and hair thickness were measured and evaluated. Furthermore, hematological tests were performed to assess the general physical condition of the participants. Results: HRT increased the telogen hair rate (P = .010, paired t test) at 3 months, improved frontal hairline thinning score (P = .008, Wilcoxon test), and increased the plucking strength (P = .013, paired t test) at 6 months. Limitations: The limitation of this study included the relatively small sample size, inability to conduct further long-term tests because of participant burden, and lack of a control group. Conclusion: The results suggested that HRT improved the appearance of the frontal hairline. As few studies have analyzed the effects of female hormones on human hair, a novel finding of this study was the effects of estradiol on the plucking strength after excluding age as a factor. We believe that these findings will contribute to understanding FPHL and developing female hormone-related treatments.

ABSTRACT

Background Hair plays a significant role in physical appearance and hair loss can profoundly affect self-esteem and mental health. Studies show that people with clinically obvious and undetectable hair loss may have dramatically decreased quality of life (QoL). This study investigated the impact of androgenic alopecia on the quality of life of male individuals in the Eastern Province of Saudi Arabia and their willingness to seek treatment. Methods In the eastern province of Saudi Arabia, a cross-sectional study was carried out among men identified with androgenic alopecia (AGA). A self-administered survey was disseminated among the patients through social media sites. The questionnaire includes fundamental demographic factors including age, place of residence, level of education, the severity of androgenic alopecia, treatment method, and Skindex-29 to assess the patient's quality of life. Results Four hundred-two male patients out of 717 participants were selected, and 158 (39.3%) were aged between 20 to 29 years old. Satisfaction with treatment medication was reported by 24 (19.5%) out of those who underwent treatment (n=123). Less effectiveness was the most common reason for treatment dissatisfaction (81, 81.8%). The overall mean Skindex-29 score was 23.2 (SD 19.6) out of 100 points. Younger age, suffering hair loss for a shorter duration, undergoing alopecia treatment, being diagnosed with alopecia by a medical doctor, and having a moderate level of AGA were the factors that greatly affected the patient's QoL. Conclusion Consistent with the literature, this study showed that AGA significantly impaired patients' QoL. Among QoL domains, the symptoms domain had a greater effect on patients than the emotions or functional domains. Younger males who were suffering recently from hair loss and were diagnosed with AGA by the medical doctor demonstrated greater QoL impairment than the rest of the patients. A multicenter study may result in a better representation of the impact of QoL in patients with AGA.
