Focal Resolution of Alopecia Areata in Response to Potential Smartwatch-Mediated Photobiomodulation

The document discusses a case where a patient with refractory alopecia universalis experienced significant hair regrowth in a specific area beneath a smartwatch. The smartwatch emits green, red, and infrared light, which is used to monitor vital signs. This observation supports the potential use of photobiomodulation, a light therapy traditionally using red and near-infrared light, as a treatment for alopecia areata.
