Abstract
- Low-level laser or light therapy (LLLT) or photobiomodulation therapy has been widely investigated for hair growth and recovery in alopecia. This review investigates the documented effects of LLLT on androgenetic alopecia (AGA) by evaluating articles on the treatment of AGA using LLLT published in the past 10 years in the PubMed database. A total of 11 clinical studies were included in the said online database. Despite various parameters and conditions, the clinical trials reported that compared to the control group, applying LLLT to alopecia significantly increases the density, thickness, and number of hairs. In a recent study, the combination of using existing drugs and other treatments with LLTT significantly improved hair loss.
