Hair loss is not always interesting. It can be more. You begin to notice a little skin in the harsh light of the bathroom; a small bald spot when you tie your hair in a ponytail. The shower pan is more clogged than usual. Not so long ago, hair removal treatments meant scalp treatments, extensions, or a flight to Turkey. Fortunately, red light therapy brings the possibility of hair growth in the comfort of your own home—no medical appointments required.
To continue skin rejuvenation, medical studies say Red light therapy can help energize hair follicles, increase blood circulation in the scalp, reduce inflammation, and reduce the level of dihydrotestosterone-a hormone that causes hair loss and thinning. Red light therapy also helps produce adenosine triphosphate (ATP), which helps supply oxygen and blood to the scalp and activates the follicles to stay in the hair growth phase.
To find out the best hair light treatment for hair growth, I enlisted five WIRED hair reviewers who have had their own hair done. We tried red light hats, sleeveless hats with full scalp, and laser therapy (LLLT) or photobiomodulation devices for 16 weeks. Along the way, I looked at the research, talked to dermatologists, and saw how easy it is to use. These are interests that produced meaningful results and made us believe.

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

CurrentBody’s LED Hair Growth Cap is a wearable, wireless, Bluetooth-enabled device designed to improve the density, thickness, and texture of hair. After 12 weeks, I didn’t notice a difference in hair length—I was shaved in the middle of the test—but I did notice new follicles growing on the sides of my head and sides. My hairstylist said that my hair was getting too thick, and I noticed that my hair was prone to breakage and tangles when I washed it. A balding friend of mine also tried the CurrentBody helmet, and noticed that her hair grew back and that her skin was plumper.
