Cortisol, a biomarker of stress, is slowly deposited into the growing hair strands on the head. Meyer, Novak, Hamel, and Rosenberg (2014) established a method for hair cortisol extraction and analysis, and showed that hair cortisol can serve as an integrated measure of psychophysiological stress activity during the period of hormone incorporation into the hair. The hair sample collection methods offered, however, (ie, cutting as close to the scalp as possible with scissors) is inefficient when collecting samples among participants with Afro‐textured and extremely short‐length hair types. In this article, we propose an alternative method for collecting hair among this group.
