The exact mechanism of how LLLT works has not yet been explored, at this current time research has only indicated how it is believed to work. Some studies have shown that the treatment has promoted hair growth.
The treatment has however only highlighted promoted growth on those who has Androgenetic alopecia. The treatment works best on those with thinning hair and pattern baldness caused by a hereditary condition. The treatment will not work on everyone, and it is unlikely to work on those with very little to no hair.
