“Vellus hair is a fancy term for peach fuzz,” board-certified advanced aesthetics nurse practitioner and founder of Effacè Aesthetics, Roberta Moradfar, tells POPSUGAR. “These are the fine, very light-pigmented hairs that can be found all over the body including the face, ears, and nose. On certain areas of the body, hormonal changes may turn vellus hairs to thick, coarse hairs – for example the pubic area and armpits.”
