Efficacy of Local and Whole‐Body Phototherapy for the Treatment of Various Types of Alopecia Areata

Phototherapy is an effective treatment for certain subtypes of AA, especially when initiated early after disease onset. Local irradiation showed comparable effectiveness to whole-body irradiation. These findings support the early initiation of phototherapy as a therapeutic strategy for AA, particularly in older patients and those with limited disease duration.
