TLDR The Lexington LaserComb helped regrow hair in mice with a condition similar to human hair loss.

In a 2012 study involving 14 C3H/HeJ mice with induced alopecia areata (AA), researchers found that the HairMax LaserComb, a low-level laser therapy device, promoted hair regrowth. The mice were divided into two groups: Group I received actual LaserComb treatment (655 nm wavelength) for 20 seconds daily, three times a week for 6 weeks, while Group II received a sham treatment. Results showed that all mice in Group I exhibited hair regrowth, with histological analysis revealing an increased number of anagen hair follicles, compared to the sham-treated group which had hair follicles in the telogen phase without hair shafts. The study suggests the LaserComb could be an effective AA treatment, pending confirmation from human trials. The study was supported by Locks of Love and NIH/NIAMS, and the LaserCombs were provided by Lexington International, LLC.
