Red light therapy has moved from the dermatology office into everyday life, and the latest version fits under a baseball cap. Dr. Morgana Colombo, MD, FAAD, board-certified dermatologist at Integrated Dermatology of Reston and founder of Vidaderma, shared her perspective with Vogue for its review of the HigherDOSE Red Light Hat. Here's what to know before you try red light therapy for your hair.
"Hair loss can be incredibly emotional for both women and men, so anything that makes treatment feel more private, convenient, and normalized can be valuable." Dr. Morgana Colombo, via Vogue
What is red light therapy for hair?
Red light therapy, also called low-level light therapy or photobiomodulation, uses red wavelengths of light on the scalp to support the hair follicle. At-home versions now come as caps, helmets, and headbands designed for short, regular sessions.
What matters most with an at-home device?
In her conversation with Vogue, Dr. Colombo pointed to the factor that often matters more than the technology itself:
"One of the biggest challenges with any at-home treatment is adherence." Dr. Morgana Colombo, via Vogue
If a device feels bulky, uncomfortable, or makes you self-conscious, you're less likely to use it consistently, and consistency is especially important with hair-growth treatments. In Dr. Colombo's view, the best device isn't just the one with good technology. It's the one you'll actually use.
How long until you see results?
Like any hair treatment, red light therapy is a long game, and Dr. Colombo was clear about setting realistic expectations:
"Hair loss in particular requires months of consistent therapy for any noticeable results. Depending on the individual and the cause of the hair loss, meaningful improvement may take three to six months or longer to appreciate." Dr. Morgana Colombo, via Vogue
Most at-home devices recommend short, frequent sessions, so give it a few months of steady use before judging results.
