September 2017 in “Lasers in Surgery and Medicine” LED light therapy may help hair growth by activating certain cell pathways.
January 2026 in “Forum Dermatologicum” Light-emitting diode (LED) photobiomodulation (PBM) is a safe and promising treatment in dermatology, showing moderate efficacy for conditions like inflammatory acne, photoaging, and androgenetic alopecia. Red and near-infrared (NIR) light can improve skin texture and reduce wrinkles, while low-level light therapy (LLLT) significantly increases hair density in androgenetic alopecia. However, consumer devices often have lower irradiance and fluence, leading to limited efficacy. The review highlights the need for standardization of device parameters and high-quality trials, especially for consumer devices, to better establish their clinical benefits. LED therapy is generally supportive rather than primary, with a favorable safety profile and mild, transient adverse effects.
