Efficacy and Safety of a Botanical Topical Serum on Male and Female Androgenetic Alopecia

Abstract

Androgenetic alopecia (AGA) is a common form of hair loss in both men and women, it affects up to 80% of men and 50% of women during their life. The current treatments approved for AGA are limited, inconstantly effective and might be associated with adverse events. The aim of this study was to evaluate the efficacy and safety of a botanical topical serum (SERUM THICKER) applied for 6 months in 14 males and 10 females with mild to moderate androgenetic alopecia. The hair parameters were assessed using trichoscopy images obtained with high resolution camera FotoFinder Leviacam &#174; and analyzed with optimized software from TrichoLAB TM and Vitual tattoo TM technology. Hair loss was assessed using a wash-test procedure, and self-assessments were collected via questionnaires. Both at 28 days and 168 days, a significant increase of the hair density was observed, respectively +4.8% (p = 0.038); +11.7% (p < 0.001) for 1 application per day and +5.2% (p = 0.032); +9% (p < 0.001) for 2 applications/week. Reported to the whole scalp, this represents an estimation of hair gain of 7000 hair in 6 months for subjects applying SERUM THICKER once a day and 5000 hair for subjects applying SERUM THICKER twice then once a week. Although, the analysis of hair shedding during washing did not permit to show a time effect or any effect of the application frequency, the analysis showed a marginal time effect in the group treated once a day (p = 0.0674). Regarding efficacy on hair loss and regrowth, although no statistical analysis were performed, it seems that for all questions and for both groups the positive answers were higher after 6 months of treatment than after 1 month. SERUM THICKER represents an interesting, effective, well-tolerated and safe multitarget treatment to address mild to moderate AGA in male and female. Efficacy was observed from one application per week and seems greater once applied once daily.
