Hair Pull Test: A Clinical Update for Patients with Asian- and Afro-Textured Hair

This study updated the hair-pull test guidelines to include individuals with Afro- and Asian-textured hair, involving 198 participants. It confirmed that pulling 2 or fewer hairs is considered normal across all hair textures, aligning with previous guidelines primarily based on Caucasian hair. The study found no significant impact of hair-care practices, such as washing or brushing, on the test results. Afro-textured hair showed more breakage due to its structural characteristics, but chemical treatments did not significantly alter the number of hairs removed. The study emphasized the need for consistent interpretation of the hair-pull test across different hair types.
