Contributors photograph and film finished haircuts and styling, framed on the hair, faces avoided, in salons, barbershops and homes across a global base strongest in Southeast Asia, the United States and Europe, so textures, cuts and chemical treatments run wider than studio sets, from thick straight hair to tight curls, bleached and relaxed. No style or texture labels; the vocabulary is easy to annotate. Hair is hard to segment, render and edit, and public hair data is dominated by face datasets and small studio captures, mostly of straight hair. For virtual try-on, segmentation and generation, and for beauty-tech products sold worldwide, texture and finish data at a scale studio sets do not reach.
