Abstract
INTRODUCTION: Chronic telogen effluvium (TE) and androgenetic alopecia represent two prevalent forms of hair loss that can significantly impact individuals' quality of life. Insufficiency of essential micronutrients has been associated with hair loss. The objective of this study was to evaluate the safety and efficacy of an oral supplement containing l-Cystine, Serenoa repens, Cucurbita pepo, Pygeum africanum, vitamins, and micronutrients in chronic TE (CTE) and androgenetic alopecia (AGA). METHODS: Eighty patients of both sexes aged 18-60 years with CTE or AGA were randomized to receive one capsule daily of the oral supplement or placebo for 6 months. Dermatological evaluations, clinical pictures and phototrichograms were done at baseline, 3 months and 6 months. The overall hair volume and appearance were assessed before and after treatment as well as subject's self-assessment via standardized questionnaire. RESULTS: Hair density increased by 9.9 hairs/cm(2) after 3 months and 12.3 hairs/cm(2) after 6 months in the oral supplement group and it is statistically significant when compared to placebo. Overall hair volume after 1, 3, and 6 months is better in the supplement group than in the placebo group. The oral supplement was well tolerated. No moderate or severe adverse events were reported. CONCLUSION: Oral supplementation can increase hair density, anagen hairs, and overall hair appearance in patients with AGA or CTE.
