Secondary outcomes
SIDE EFFECT
Global photographic assessment was conducted at baseline, 12 and 24 weeks at the clinic where standardized photographs of the scalp were taken. Then, a panel of 3 blinded dermatologists and the blinded outcome assessor compared baseline with follow-up photographs of each subject and used a 7-point scale to rate the hair growth. The choices ranged from − 3 = greatly decreased to 3 = greatly increased.Treatment safety was evaluated by questioning patients every 6 weeks if they had suffered from any side effects since the last interview. Patients were informed about minoxidil side effects, and if any serious side effect had occurred, patients would have been withdrawn from the study and treated for free.
