Hair loss can be triggered by illness, stress, or genetics. While home remedies like onion or rosemary oil are popular, tech-based solutions are gaining attention too. One such option is red light therapy, recently endorsed by American tech entrepreneur Bryan Johnson as part of his hair restoration routine.

The 43-year-old, who tends to share health hacks and longevity tips, had written, “Red light cap—six minutes a day, and you can be doing your morning routine as you wear it.”

WHAT IS RED LIGHT THERAPY?

Red light therapy (RLT), also called low-level laser therapy (LLLT) or photobiomodulation (PBM), is a noninvasive treatment used in dermatology for healing, reducing inflammation, and rejuvenation.
