Brief summary
The purpose of this study is to evaluate the efficacy of the HairMax LaserComb 2009 9 beam model in promoting hair growth in females diagnosed with androgenetic alopecia when treatment is applied as directed.
Detailed description
This is a randomized double-blind, control device clinical study across 5 sites, evaluating changes in terminal hair count in the evaluation zone having evidence of androgenetic alopecia (miniaturized hair). The trial with 60 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 assess at visit 4 (week 16). Safety analysis will be assessed based on the reports of adverse events during study.

Eligibility
Inclusion criteria
* Diagnosis of androgenetic alopecia * Fitzpatrick Skin Types I-IV * Ludwig I-4, II-1, II-2, or frontal * Active hair loss within last 12 months

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in Terminal Hair Count Week 16 and 26 Weeks Over Baseline | 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. |

Participants by arm
| Arm | Count |
|---|---|
| HairMax LaserComb 2009 9 Beam This arm involves the active LLLT device with 9 laser modules. The device is used 3 times a week for 12 minutes per session for full length of study. This device was distributed to subjects in a blinded randomized manner | 43 |
| Control Device This arm involves the use of an inactive control device that emits white light. The device is used 3 times a week for full length of study. This arm of the study was blinded and dispensed to subjects on a random basis. | 22 |

Outcome results
Changes in Terminal Hair Count Week 16 and 26 Weeks Over Baseline
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.
Time frame: Baseline, 16 weeks, 26 weeks
| Arm | Measure | Group | Value (MEAN) | Dispersion |

| Control Device | Changes in Terminal Hair Count Week 16 and 26 Weeks Over Baseline | Change at 16 weeks | 1.3 hairs per cm^2 | Standard Deviation 14.67 |
| Control Device | Changes in Terminal Hair Count Week 16 and 26 Weeks Over Baseline | Change at 26 weeks | 2.8 hairs per cm^2 | Standard Deviation 16.48 |
