Hair loss isn’t always dramatic. It can be incremental. 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.

Updated June 2026: I’ve added the GroWell Laser Hair Growth Cap, Laduora Duo 4-in-1 Pod-Based Scalp and Hair Care Device, and the Hairmax LaserBand 82 ComfortFlex. I’ve added an FAQ section. I also updated product information, links, and prices.

CurrentBody’s LED Hair Growth Helmet is a wearable, cord-free, Bluetooth-enabled device designed to improve hair density, thickness, and overall condition. After 12 weeks, I didn’t notice a difference in hair length—I did get a haircut halfway through testing—but I did spot new follicles sprouting along my scalp and sideburn area. My hairstylist mentioned that my hair felt thicker, and I noticed less breakage and hair caught in bristles when brushing. My balding roommate also tested the CurrentBody helmet, and he noted that his hair also felt thicker and that there was new growth around the scalp.
