Best Red-Light Therapy for Hair Restoration and Regrowth (2026)

Article excerpt

Wired tested red-light therapy devices on hair loss over 16 weeks and observed visible regrowth in participants using the technology daily. Red-light therapy, which uses specific wavelengths to stimulate hair follicles, has gained traction as a non-invasive alternative to pharmaceutical treatments like minoxidil and finasteride. The publication evaluated multiple devices for effectiveness, ease of use, and cost, finding that results varied depending on the device's power output and consistency of application. While the science behind red light's effects on hair growth shows promise in clinical studies, individual outcomes depend on factors like hair loss severity and genetic predisposition. Wired's testing offers practical guidance for consumers considering this treatment option.
