Duration of Minoxidil Therapy to Yield Maximum Benefit

The study investigated the duration of minoxidil therapy needed to achieve maximum benefit in hair growth. It noted a decrease in total hair counts between the 12th and 30th month of use, particularly in subjects with average and above-average responses. The study began with 149 subjects, with 102 completing 12 months and 89 completing two years. Only 54 participants (50 men and 4 women) continued into the third year. The findings suggested that while minoxidil was effective, its benefits might diminish over time, highlighting the importance of long-term follow-up to determine the optimal duration of therapy.
