TLDR UVFT helps diagnose hair and scalp diseases by showing different fluorescence patterns.

The study investigates the use of ultraviolet-induced fluorescence trichoscopy (UVFT) in diagnosing hair and scalp diseases, involving 201 patients with various conditions. UVFT helps differentiate between scarring and non-scarring alopecias by revealing distinct fluorescence patterns, such as pink-red or green follicular fluorescence in non-scarring alopecias and white-blue perifollicular fluorescence in scarring alopecias. It also aids in distinguishing psoriasis from seborrheic dermatitis through unique fluorescence characteristics. Despite being limited to Caucasian patients and lacking histopathological correlation, UVFT shows promise in enhancing diagnostic accuracy and selecting biopsy sites by detecting subclinical inflammation. Further research is needed to validate these findings across diverse populations.
