“…Yellow dots are uncommon, as empty follicles appear white instead of yellow [26,29]. Although some researchers (Bapu et al [31], Mane et al [32], and Guttikonda et al [33]) reported yellow dots as the most common dermoscopic feature of alopecia areata in dark-skinned Indian patients, their pictures document white rather than yellow dots.…”

Trichoscopy (dermoscopy of the hair and scalp) is a technique that improves diagnostic accuracy and follow-up with hair and scalp disorders. Although several studies of trichoscopy have been made in Caucasian and Asian populations, little has been published regarding trichoscopy findings in skin of color, despite the great prevalence of hair diseases in populations with this kind of skin. The aim of this review was to describe the trichoscopic features of normal scalp and of hair disorders in patients with dark skin phototypes. This will help dermatologists to distinguish between unique trichoscopic features of dark skin, and allow them to provide more accurate diagnoses and treatments for these patients.

Background: No scoring systems to evaluate overall hair loss activity in alopecia areata (AA) have been established. Objective: We sought to develop a measurement tool (Alopecia Areata Progression Index, AAPI) for the evaluation of overall hair loss activity in AA patients with pigmented hair. Methods: The scalp surface area was divided into 4 quadrants. In each quadrant, hair loss activity was scored on the basis of the percentage of alopecic area, clinical findings associated with hair loss. The AAPI was measured in 17 patients with different severities of AA. Results: Interobserver and intraobserver reliabilities were assessed by 4 investigators. A significant correlation of the total AAPI was found among the 4 investigators. In addition, intraobserver reliability was excellent, and interobserver reliability was statistically reliable. Conclusion: The AAPI seems to represent a system capable of truly quantifying overall hair loss activity in AA patients with different severity, demonstrating trustworthy interobserver and intraobserver reliability.

“…[1][2][3] Dermoscopy of scalp disorders has been performed in our Hair Diseases Clinic with a handheld dermoscope (DermLite II ProHR 3Gen [3Gen; San Juan Capistrano, CA] attached to a Sony Cybershot digital camera [DSC-W55; Sony; Tokyo, Japan; 310-30 magnification]).We have observed small pinpoint white dots regularly distributed on the scalp of patients with Fitzpatrick skin phototypes V and VI and in sunexposed areas of patients with phototypes III and IV. These structures were seen in normal scalps and in patients with frontal fibrosing alopecia (FFA; Fig 1), lichen planopilaris (LPP), alopecia areata, androgenetic alopecia (AGA), and central centrifugal cicatricial alopecia (CCCA).…”
