A hair growth cap is a specialized device worn on the head to stimulate hair growth. One common type is the laser hair growth cap, which utilizes low-level laser therapy (LLLT) to promote follicle rejuvenation.
Hair growth caps have gained prominence as a non-invasive and convenient method to address hair loss and thinning. LLLT, in particular, has been shown to increase blood flow, reduce inflammation, and stimulate the production of growth factors. Historically, laser therapy has been successfully employed in various medical fields, including dermatology.
