Male baldness is not only the decrease of face value, but also the risk of physical function decline in some male baldness. In addition to genetic factors, male baldness is also closely related to personal physique. Although some men are bald, their physical function has not declined, which is a genetic factor, not a physical function. Moreover, some men are bald, and there is no baldness gene in the family, which may be caused by the decline of physical function. No matter what kind of factors, male baldness should be paid attention to, and it is necessary to have an annual physical examination.
