Red Light Therapy has been studied as a treatment for hair loss, particularly for conditions like androgenetic alopecia (pattern baldness). Research suggests that red light (630-660nm) can stimulate hair follicles, increase blood circulation to the scalp, and encourage hair regrowth.
Key Findings from Multiple Studies:
- A 2014 study found that men and women with androgenetic alopecia experienced significant hair regrowth after 24 weeks of RLT treatments.
- A 2019 review confirmed that red light therapy is a safe and effective treatment for hair loss with minimal side effects.
- A 2021 study suggested that combining RLT with topical treatments like minoxidil may enhance results for hair regrowth.
Implications:
These studies suggest that red light therapy between 630-850nm may help stimulate hair regrowth, strengthen hair follicles, and improve scalp health over time. Regular use (3-4 times per week) may be beneficial for individuals experiencing hair thinning or hair loss.
