The current study aims to show efficacy of twice daily application of 5% Minoxidil Topical Foam (MTF) formulation compared to placebo in the temple region of male patients with androgenetic alopecia after 24 weeks as well as to gain long-term data on the efficacy and safety of 5% MTF in male subjects with AGA in temple and vertex region, over a period of 2 years. Objective and subjective efficacy measures will be compared to baseline. Moreover, all patients will get the equal treatment and measurements in the vertex region to enable comparison of the efficacy of 5% Minoxidil Topical Foam in the temples not only to baseline but also to vertex region. Additionally safety assessments will be performed throughout the whole study.
