Peach fuzz hair, characterized as fine, vellus hairs, thinly covers various body parts, particularly evident on the face during puberty. Women typically have finer peach fuzz than men.
Although often considered a cosmetic concern, peach fuzz hair plays essential roles: it provides insulation, protects sensitive areas, and acts as a sensory organ. Notably, in the early 1900s, peach fuzz hair became the subject of research due to its potential in cosmetics and hair transplantation.
