You can inherit this trait from either your mother’s or your father’s side of the family. And while hair loss or thinning hair is often thought of as something that only affects older people, the condition can start as early as your teens, 20s or 30s.
Most people experience some hair thinning as they age, but not everyone is affected to the same degree.
Men with male pattern baldness usually develop a receding hairline, hair loss at the crown, or both. Over time, men with hereditary hair loss can end up becoming completely bald.
Women with female pattern baldness, on the other hand, tend to develop thinning hair as opposed to total hair loss. This usually sees their hair become thinner across the scalp, especially at the hairline. The crown may be affected, but hereditary hair loss in women rarely proceeds to total baldness.
