Name Ingredients:
Low-level laser therapy (LLLT) is an FDA-cleared therapy offered at home and in the clinic to those with androgenic alopecia. LLLT leverages near-infrared and infrared light to promote hair growth.
Key insights:
- The ex vivo histological data suggests that LLLT can stimulate the re-entry into anagen (growing phase) from telogen (non-growing phase) and increase the rate of cellular growth (proliferation) in anagen hair follicles.
- It is thought that LLLT activates heat shock proteins, specifically HSP27 (involved in cell proliferation), improves tissue oxygenation, increases blood flow, generates acute tissue inflammation, and inhibits 5-alpha-reductase.
- The in vivo (in animals) data suggests that LLLT can improve hair growth in a chemotherapy-induced alopecia rat model and significantly increase the percentage of anagen hair follicles at 24-hour intervals over five days in Swiss albino mice.
- The clinical data suggests that various strengths and lengths of time of use of LLLT can improve hair counts compared to a placebo and improve tensile strength and hair thickness in both men and women.
- While LLLT appears to be effective from the published results, our members suggest a less significant improvement in hair regrowth.
