From www.ncbi.nlm.nih.gov: 🌋🌋🌋⚡️⚡️⚡️ "LLLT was discovered serendipitously in the 1960s when mice irradiated with a low fluence red laser grew hair. Since that time LLLT has demonstrated promise in conditions from wound healing to stroke recovery, from treatment of musculoskeletal pain to prevention of mucositis.
😃😃😃 Animal and human data have slowly accumulated supporting LLLT for hair growth (Table 1). LLLT appears to improve a variety of non-scarring alopecias—AGA, AA, and chemotherapy-induced alopecia. Based on the studies demonstrating LLLT's effects on promoting graft survival, it may be further suggested to have a potential to be used during the immediate period of post-hair transplant surgery to facilitate the healing process and enhance viability and earlier growth of the grafts [60,61]. 😜😜😜 While mechanisms are still emerging, LLLT may increase anagen hairs through release of NO from CCO by photodissociation and LLLT may reduce inflammation in AA. However, more studies are needed to optimize treatment parameters and determine long-term efficacy as well as safety of emerging LLLT technologies. 😎😎😎 Most studies investigating effects of LLLT on hair growth have used wavelengths that range from 635 to 650 nm, but as of today no study has compared the effect of near-infrared wavelengths such as 810 nm, which have deeper penetrating capacities, to red light. Moreover, further studies are required to compare efficacy of different light sources (continuous vs. pulsed) and methods of light delivery (laser vs. LED)."👌👌🙉🙈🙊🙊
