What Does This Study Tell Us?
A recent analysis of hair count data in four multicenter studies evaluating both Minoxidil Topical Solution 2% and 5% (two studies in females and two in males) has substantiated that hair loss can be stabilized with Minoxidil Topical Solution use. The hair count stabilization data, based on a calculation of increased or unchanged number of non-vellus hairs compared to baseline, showed that for males the stabilization (percent of subjects) was 90% and 77% for MTS 2% users, and 96% and 75% for Minoxidil Topical Solution 5% users.
Study Information and Results:
A post-marketing surveillance study in over 11,000 minoxidil topical solution (MTS) 2% users with androgenetic alopecia demonstrated that 4 out of 5 subjects experienced a slowing or stopping of hair loss with Minoxidil Topical Solution (Rogaine/Regaine).
Although subjects opinion of treatment results were considered to be important, further corroboration of these results was conducted and other data have been generated to support stabilization of hair loss.
For females, the percentages were 87% and 88% for Minoxidil Topical Solution 2% users, and 85% and 89% for Minoxidil Topical Solution 5% users. In addition, using hair count data in subjects treated with MTS 2% and 3% for up to 5 years (Olsen et al [JAAD 1990;22:643-46), it was estimated that hair loss stabilized in 4 out of 5 (80%) subjects.
An evaluation of global photography, carried out by two blinded dermatology experts for a registration trial of Minoxidil Topical Solution 5% in men, further supports stabilization of hair loss. One expert evaluated hair loss stabilization to be 94% in both Minoxidil Topical Solution 2% and 5% Minoxidil Topical Solution groups.
The second expert reported stabilization in 85% of the subjects using MTS 2%, and 83% using Minoxidil Topical Solution 5%. In conclusion, multiple studies support the ability of Minoxidil Topical Solution to stabilize hair loss in 4 out of 5 users.
Conclusions:
Conclusions: 4 out of 5 Minoxidil 2% and Minoxidil 5% users were shown to maintain HAIR COUNT after 5 years of use. This implies an 80% effectiveness rate at maintaining hair count on Minoxidil Those of you who are familiar with the other well established Minoxidil studies will realize that these results differ greatly.
