What is cold laser therapy?
Cold laser therapy, also known as low-level laser therapy (LLLT), is a non-invasive treatment that uses specific wavelengths of light to stimulate hair follicles and improve growth.
It works by enhancing cellular activity and increasing blood flow in the scalp, which can promote hair regrowth in thinning areas.
Red light therapy devices often fall under this category, with clinical studies showing positive outcomes for patients with androgenic alopecia and diffuse thinning.
