What is the life span of a human body hair?
Hair shedding usually happens after the growth phase (anagen) stops and hair goes to the resting phase (telogen). The longer the growth cycle, the shorter is the resting (telogen) phase, and the the longer is the final length of hair. Scalp hair can grow to become very long because its long growth phase (2 – 6 years) and its relative short resting phase (2 – 6 months) when compared to the growth phase. In contrast, eyebrow or body hair with shorter growth, as a disproportional longer resting phase can never grow to become long. Facial hair in men should follow a similar pattern to the scalp hair (short shedding phase and long growth phase). There isn’t a way to reduce hair growth for any one. Our genes predetermine the amount of hair we have. I know facial hair can be a nuisance. You can use hair creme remover for your face, or you can wax it. If it’s at all possible, you can look into laser hair removal.
