Here's How to Use Red Light Therapy for Fuller Hair at Home

"Red light therapy can help energize hair follicles, increase blood circulation in the scalp, reduce inflammation, and lower dihydrotestosterone levels-a hormone that causes hair loss and thinning. Red light therapy also supports adenosine triphosphate (ATP) production, which helps provide oxygen and blood flow to the scalp and triggers follicles to remain in the hair growth phase."

"Each panel on the helmet has 12 red lights (120 total), which are on a spectrum of 620 to 660 nanometers (nm). The 620-nm red light helps improve scalp health by promoting circulation, and the 660-nm red light penetrates deeper, reaching through the epidermis and dermis to the hypodermis, where it stimulates growth and repair at the follicle root."

Hair loss often develops gradually through increased scalp visibility, bald spots, and excessive shedding. Traditional treatments included topical remedies, supplements, or overseas procedures. Red light therapy provides an accessible home solution for hair regrowth. The therapy works by energizing hair follicles, improving blood circulation to the scalp, reducing inflammation, and lowering dihydrotestosterone levels that cause hair loss. Red light therapy also enhances ATP production, delivering oxygen and blood flow to the scalp while keeping follicles in the growth phase. Reviewers tested red light therapy caps, hands-free helmets with full scalp coverage, and photobiomodulation devices over 16 weeks, consulting dermatologists and tracking results.
