September 2024 in “Egyptian Journal of Dermatology and Venerology” In this interventional study on female-pattern hair loss, researchers found that fractional CO2 laser therapy alone improved hair growth, as evidenced by increased hair count, thickness, density, and patient satisfaction compared to saline controls. However, the precise mechanisms behind these effects require further investigation.

March 2019 in “Journal of Pure and Applied Microbiology” This study investigated the anti-inflammatory effects of a 940nm diode laser in Wistar rats with carrageenan-induced arthritis and found that a 74J/cm² energy density significantly reduced edema and restored function, whereas 171J/cm² neared thermal exposure limits for the skin.
December 1997 in “Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE” This study concluded that low energy laser therapy may effectively complement classical treatment for scalp alopecia, leading to faster results, although long-term maintenance still requires ongoing classical therapy.
May 2026 in “Skin Appendage Disorders” This study determined that low-level light therapy and fractional lasers are effective and safe treatments for androgenetic alopecia, especially when combined with other agents like minoxidil, PRP, or growth factors.
This study found that low-level light therapy and fractional lasers are effective and safe treatments for androgenetic alopecia, with the greatest improvements in hair density and thickness seen in combination therapies.
