TLDR Laser and light therapies can help regrow hair but need more research for best results.

The document reviewed various laser and light-based therapies for treating hair loss, focusing on their efficacy and mechanisms. It highlighted studies on different laser types, such as fractional photothermolysis and low-level laser therapy (LLLT), which were shown to stimulate hair growth by enhancing cellular activity and promoting the expression of growth factors like Wnt/beta-catenin. Clinical trials, including those with devices like the HairMax LaserComb, demonstrated positive outcomes in both male and female pattern hair loss. The studies varied in size, with some involving small case series and others being larger, multicenter trials. Overall, these therapies were found to be promising for hair regrowth, though the document noted the need for further research to optimize treatment parameters and confirm long-term efficacy.
