You start noticing a bit more scalp in harsh bathroom lighting; a tiny bald spot when you tie your hair up in a ponytail. The shower drain is more clogged than usual. Not long ago, hair-loss treatments meant topical remedies, supplements, or a flight to Turkey. Luckily, red-light therapy brings the potential for hair regrowth into your home—no clinical appointment required.
Beyond skin rejuvenation, clinical studies suggest 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.
To determine the best red-light therapy for hair growth, I tapped five WIRED tech reviewers who've dealt with hair loss themselves. We assessed red-light therapy caps, hands-free helmets with full scalp coverage, and low-level laser therapy (LLLT) or photobiomodulation devices for 16 weeks. Along the way, I reviewed the research, spoke with dermatologists, and tracked ease of use. These are the favorites that produced meaningful results and earned our trust.
