Clare Mackay (@thetrichprof) is a Professor of Neuroscience at the University of Oxford who studies, advocates for, and lives with body-focused repetitive behaviours (BFRBs). She has spent 30 years studying a variety of brain disorders, including epilepsy, psychosis and dementia, primarily using neuroimaging technology, and has led a number of major research and infrastructure projects, In 2023 she began to turn her attention to the disorder that had been with her all along: hair-pulling (trichotillomania). She has subsequently developed several research studies and collaborations, hosted the first ever UK Conference for BFRBs, authored a book (Keep Your Hair On: Understanding urges to pick, pull and bite, Little Brown Book Group, 2026), and uses her platform to educate, raise awareness and reduce stigma for people living with BFRBs.
