Brief summary

The purpose of this study is to evaluate the change in terminal hair count at 16 and 26 weeks compared to baseline measurements.

Detailed description

This is randomized, double-blind, control device clinical study across 3 sites, evaluating changes in terminal hair-count in the evaluation zone having evidence of androgenetic alopecia (miniaturized hair). The trial will involve approximately 75 male subjects who have been diagnosed with androgenetic alopecia, who are between 25 and 60 years of age, have Fitzpatrick Skin Types I-IV, with classifications of Norwood-Hamilton IIa to V, have active hair loss within the last 12 months. Subjects will use the device on three non-consecutive days a week as directed per device for 26 weeks treatment duration. Safety analysis will be assessed based on the reports of adverse events during study.

Interventions

Device application 3 times week (non-consecutive days), for 26 weeks

Device is used 3 times a week on non-consecutive days

The active group was compared to the control device using least squares means with a two-sided test at the 5% level of significance.
