Man hair encompasses the facial and cranial hair that grows on adult males. This body hair, in contrast to female hair, is commonly darker, coarser, and thicker due to higher levels of testosterone. An example of man hair is the beard, which has been a prevalent cultural symbol throughout history.
Besides its cultural significance, man hair plays a role in thermoregulation and provides facial protection. Historically, man hair has been intertwined with masculinity and has been shaped by social norms and fashion trends.
