Men typically start balding due to male pattern baldness, which is largely influenced by genetics and hormone levels. The most common age range when men begin to notice hair loss is between their late teens and early 30s. Specifically:
- According to the National Institute for Health and Care Excellence (NICE), many men who inherit male pattern baldness start losing hair between ages 20 and 25.
- Studies show by age 30, about 25-30% of men have started balding, and by age 50, approximately 50% show noticeable hair loss.
- Early onset male pattern baldness can even begin in the late teens, with about 15% of teenage boys exhibiting early signs.
- Hair loss tends to progress gradually, with the likelihood and severity increasing with age.
- For some men, balding may start later in their 30s or 40s.
In summary, men can start balding as early as their late teens and early 20s, but it is most commonly observed starting in the 20s to early 30s, affecting about half of men by age 40 to 50.
