Improved trichoscopic assessment of yellow dots using Sub-Ultraviolet Light

Supplementary material Figure S1. Trichoscopy in alopecia areata obtained under conventional non-polarized dermoscopy. Presence of diffuse yellow dots with regular distribution along the lesion. Figure S2. Trichoscopy in scarring alopecia obtained under conventional polarized dermoscopy. Patch of hair loss without visible follicular openings. Figure S3. Trichoscopy in scarring alopecia obtained under 405 nm near-ultraviolet light. Both images were taken using a commercially available DZ-D100 dermoscope (Casio Computer Co., Ltd., Tokyo, Japan).
