TLDR Coudability hairs are useful markers for alopecia areata activity.
The study assessed the usefulness of "coudability hairs" as a clinical indicator for alopecia areata (AA) using trichoscopy on 100 East Asian patients. The results showed that coudability scores positively correlated with AA disease activity, hair-pull tests, short disease duration, black dots, and exclamation-mark hairs, while negatively correlating with short vellus hairs. The study concluded that coudability hairs are valuable markers for AA disease activity and can serve as a substitute for the hair-pull test.
