New to Minoxidil? There is a guide in the encyclopedia. Read the guide → Studysummary In this study, minoxidil 2% produced satisfactory esthetical results in about 30% of patients, but placebo-treated subjects experienced increased hair counts without a cosmetic benefit, possibly due to seasonal variations and hair classification issues.

The clinical double-blind trials conducted in 1990 demonstrated that topical minoxidil 2% was effective in producing satisfactory aesthetic results in approximately 30% of treated patients. However, the study noted an unclear increase in hair count among placebo-treated subjects, which was hypothesized to be due to not accounting for seasonal hair density variations and confusion in categorizing hair types. The placebo did not significantly increase terminal hair count, explaining the lack of cosmetic benefit despite an increase in "non-vello" hairs.
