Alopecia Areata
Yellow Dots and Short Vellus Hairs
Yellow dots and short vellus hairs are the most commonly seen dermatoscopic features of alopecia areata. Both are related with severity of disease being more common in advanced alopecia areata.
Yellow dots are hair follicles that are plugged with keratin. Short vellus hairs in alopecia areata represent hairs that are trying to regrow.
