BLIND, HAIR LOSS
Hair loss is a common problem that affects up to 50 percent of men and women.Some limitations should be considered in evaluating our results. First, the two arms of the study were slightly unbalanced (48 subjects in group A and 35 subjects in group B). This could be explained by the randomization conducted using a block of six. Although the two groups are slightly unbalanced in term of participants, demographics and baseline characteristic were similar between groups. A second limitation of this study was the trial design which was not double blind. In order to increase the internal validity of our trial, we adopted an assessor‐blinded primary outcome evaluation. Another limitation of this study was related to the relatively short duration of the treatments. However, it was adequate to observe the role of oral supplementation in improving the efficacy of the anti‐hair loss treatments generally employed.
