Ultraviolet-Induced Fluorescence Dermoscopy in Detecting Follicular Openings in Alopecia Areata

This study explores the use of ultraviolet-induced fluorescence dermoscopy (UVFD) to improve the detection of follicular openings in alopecia areata (AA), a common form of non-scarring alopecia. Traditional dermoscopy struggles with this task, especially in patients with extensive hair loss or darker skin. UVFD, using a 365-nm UV-LED light, was tested on 25 AA patients, revealing that 20 showed prominent fluorescence in follicular openings, aiding in distinguishing between scarring and non-scarring alopecia. This method enhances the visibility of hair follicles, providing a clearer assessment of AA severity and informing treatment strategies. However, further studies are needed to confirm its predictive value and reliability in clinical practice.
