Armpit hair in women, or axillary hair, refers to the growth of hair in the underarm area. It is a natural bodily characteristic that varies in thickness, color, and texture across individuals.
Armpit hair has several biological functions, such as providing insulation and absorbing sweat. It is also thought to have a role in pheromone production, potentially influencing social interactions. Historically, the visibility of armpit hair in women has been subject to cultural and societal norms, with varying levels of acceptability and desirability over time.
