Change in Hair Count at 16 and 26 Weeks Over Baseline [ Time Frame: Baseline, 16 weeks, 26 weeks ]
The primary analysis of effectiveness was an analysis of covariance, which separately modeled terminal hair count at Week 16 and Week 26 as a function of treatment group (HairMax LaserComb 2009 9 Beam vs.control), study center, age (as a continuous variable), and Fitzpatrick Skin Type classification (as a categorical variable with four levels). The active group was compared to the control device using least squares means with a two-sided test at the 5% level of significance.

Treatment of Androgenetic Alopecia in Females, 12 Beam
A Randomized, Double-Blind Clinical Trial to Evaluate the Safety and Efficacy of the HairMax LaserComb 2009, 12 Beam Model For The Treatment of Androgenetic Alopecia in Females
The purpose of this study is to evaluate the efficacy of the HairMax LaserComb 2009 12 beam model for androgenetic alopecia in females when treatment is applied as directed.

This is a randomized double-blind, sham controlled clinical study, evaluating changes in terminal hair count in the evaluation zone having evidence of androgenetic alopecia (miniaturized hair).

The trial with 63 female 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 Ludwig I-4, II-1, II-2, or frontal, have active hair loss within the last 12 months.

Subjects will use the device on three non-concurring days a week as directed per device for 26 weeks duration.

Initial efficacy endpoint for each subject will be assessed at visit 4 (week 16).

Safety analysis will be assessed based on the reports of adverse events during study.
