Hair loss is not always thrills. It can be more and more. You begin to notice the scalp a little in the strong light of the bath; a small bald spot where you tie your hair into a ponytail. The shower drain is more clogged than usual. Not so long ago, treating hair loss meant topical remedies, supplements, or a flight to Turkey. Fortunately, red light therapy brings the power of hair regrowth to your home—no clinic appointment necessary.
In addition to skin rejuvenation, clinical studies suggest that red light therapy can help strengthen hair follicles, increase blood circulation in the skin, reduce inflammation, and lower levels of dihydrotestosterone—a hormone that causes hair loss and thinning. Red light therapy also supports the production of adenosine triphosphate (ATP), which helps provide oxygen and blood flow to the scalp and causes follicles to stay in the hair growth phase.
To determine the best treatment for red light hair growth, I contacted five WIRED tech reviewers who have experienced hair loss themselves. We tested 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 research, talked to dermatologists, and tracked down how easy it is to use. These are favorites that have produced meaningful results and earned our trust.

CurrentBody’s LED Hair Growth Helmet is a wearable, wireless, Bluetooth device designed to improve hair density, thickness, and overall condition. After 12 weeks, I didn’t notice a difference in hair length—I cut my hair during the test—but I could see new strands sprouting around my scalp and itch. My hairstylist said my hair felt thicker, and I noticed some split ends and hair getting caught in the bristles when brushing. My balding roommate also tested the CurrentBody helmet, and noted that his hair also felt thicker and that there was new growth on his scalp.
