“…For example, black dots, tapering hairs and broken hairs correlated positively with disease activity in the trichoscopic examination. Yellow dots were the sensitive markers for the diagnosis of AA [9,10]. However, yellow dots did not reflect AA activity [13].…”

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.

The diagnosis of alopecia areata is usually based on clinical manifestations. However, there are several hair and scalp disorders that share similar clinical features with alopecia areata, such as tinea capitis, trichotillomania or traction alopecia. Trichoscopy as a fast, non-invasive and easy-to-perform technique may help to identify subtle details and establish the correct diagnosis. The aim of this review is to present the spectrum of trichoscopic findings in alopecia areata. A systematic review of the published work was performed by searching the PubMed, Scopus and EBSCO databases, complemented by a thorough hand search of reference lists. Of 427 articles retrieved, 30 studies were eligible for quantitative analysis. The reported features of alopecia areata were: yellow dots (6-100% patients), short vellus hairs (34-100%), black dots (0-84%), broken hairs (0-71%) and exclamation mark hairs (12-71%). Tapered hairs (5-81%) were reported in few studies, but a relatively high frequency of this finding in alopecia areata may indicate their important role in the differential diagnosis of hair loss. Rarely reported features, which include upright regrowing hairs (11-96%), pigtail (circle) hairs (4-61%) and Pohl-Pinkus constrictions (2-10%), may also be helpful in the diagnosis of alopecia areata. There is no pathognomonic trichoscopic marker for alopecia areata and the most common trichoscopic features are not the most specific. Therefore, the diagnosis should be based on the coexistence of several trichoscopic findings, not on the presence of a single feature.

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.
