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.

Condition or disease Intervention/treatment Phase
Androgenetic Alopecia Hair Loss Male Pattern Baldness Device: HairMax LaserComb Device: Control device Not Applicable

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.

Arm Intervention/treatment
Active Comparator: HairMax LaserComb 2009, 12 Beam
Low Level Laser Medical Device 2009 with 12 laser beams
Device: HairMax LaserComb
Device application 3 times week (non-consecutive days), for 26 weeks

Active Comparator: HairMax LaserComb 2009 9 Beam
Low Level Laser Mecial Device 2009 with 9 laser beams
Device: HairMax LaserComb
Device application 3 times week (non-consecutive days), for 26 weeks

Active Comparator: Control device
The control device appears identical to the active device, but utilizes 9 LED lights instead of laser lights. The randomized devices are blinded to the study investigator and distributed in a blinded manner to the participants.
Device: Control device
Device is used 3 times a week on non-consecutive days

Primary Outcome Measures :
  1. Changes in Terminal Hair Count at 16 and 26 Weeks Compared to Baseline in Men Diagnosed With Androgenetic Alopecia [ Time Frame: baseline, 16 and 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.
