A Clinical Comparison of Photobiomodulation Devices for the Treatment of Alopecia in All Skin Types

The document detailed a study evaluating the efficacy of four FDA-cleared photobiomodulation (PBM) devices in treating androgenetic alopecia (AGA) across various skin types. Initially, 14 subjects were enrolled, and 11 underwent treatment with six devices for three months, resulting in 62.50% showing improvements based on physician scalp exams, though 45% were still dissatisfied. The study was then extended to four months, focusing on four devices, with 30 new subjects including those with skin types V and VI. Out of these, 8 subjects with skin types I-IV and 1 with skin type V completed the study, demonstrating variable improvements. The study concluded that further research with more participants, including all skin types, is needed for more definitive results.
