A Randomized, Double-Blind, Placebo-Controlled Clinical Trial to Assess the Efficacy of a Nutritional Supplement in Female Androgenic Alopecia

Figure 3

Self-assessed hair parameters “hair shedding” and “hair thickness” improved in PPT5α-treated patients. Self-perceived hair attributes were self-assessed by a questionnaire in terms of hair shedding (a), strength of hair (b), hair thickness (c), and amount of hair (d). Each parameter was scored on a 5-point Likert scale (1 = very little, 2 = little, 3 = neutral, 4 = much, and 5 = very much). Results were expressed by means of Box–Whisker plots depicting medians, first and third quartiles, and minimum and maximum values. A value < 0.05 was considered statistically significant.
