Photobiomodulation Therapy for the Management of Chemotherapy-Induced Alopecia: Preliminary Results of a Randomized, Controlled Trial

A randomized controlled trial involving 26 breast cancer patients who underwent chemotherapy was conducted to evaluate the effectiveness of Photobiomodulation (PBM) therapy in accelerating hair regrowth. The patients were divided into two groups: a control group (no intervention) and a PBM group (three PBM sessions each week for 12 weeks, starting the last day of their chemotherapy). The results showed that one month after chemotherapy, the mean change in hair regrowth was significantly higher in the PBM group (12.5%, n=12) compared to the control group (3.9%, n=14). However, no significant difference was observed between the two groups at two and three months post-chemotherapy. These preliminary results suggest that PBM may accelerate hair regrowth after chemotherapy in breast cancer patients, but further research in a larger patient population is necessary.
