📖 Full Retelling
WIRED tech reviewers tested various red light therapy devices for hair growth over a 16-week period in early 2026, finding visible regrowth results with certain models that could provide at-home alternatives to clinical treatments. The comprehensive review included three different types of devices: wearable helmets, baseball cap-style units, and laser systems, all utilizing photobiomodulation technology to stimulate hair follicles. Red light therapy works by penetrating the scalp at specific wavelengths (typically 620-660nm) to energize hair follicles, increase blood circulation, reduce inflammation, and potentially lower dihydrotestosterone levels—a hormone linked to hair loss. The testing methodology involved daily use for 16 weeks, with dermatologist consultations and careful tracking of results, ease of use, and overall effectiveness. Among the top performers was CurrentBody's LED Hair Growth Helmet ($860), which features 120 red lights across two wavelengths and showed visible results after approximately 12 weeks of consistent use. The HigherDose Red Light Hat ($449) offered a more discreet option that reviewers found comfortable and effective for improving hair density, while the premium iRestore Elite Laser Growth Hair System ($1,899) combined lasers and LED lights for potentially faster results with just 12 minutes of daily use.

Boutayna Chokrane Gear Feb 27, 2026 5:30 AM The Best Red Light Therapy for Hair Growth Don’t fly to Turkey just yet. Our WIRED testers saw visible hair regrowth with these red light therapy devices. Courtesy of CurrentBody Save this story Save this story 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 , research suggests 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 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 three 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 or photobiomodulation devices for 16 weeks. Along the way, we reviewed the research, spoke with dermatologists, and tracked ease of use. These are the favorites that produced meaningful results and earned our trust.
