The Common Causes of Hair Losses
Genetics
98 percent of balding in men and 50
percent in women are caused by genetics. We can often
tell by looking at our parents. In more serious cases,
we can already tell the sign of oncoming balding by
the time we are 30.
However, only 7 percent of men fall
into the most severe form of balding which only leaves
3 percent of hair around the side and back of the head.
The pattern of male baldness usually
falls under one of the categories of the Norwood calssification
system below.
In
male pattern baldness, hair almost always remain at
the sides and back of the head.
For
women, hair loss occurs as overall thinning, including
the sides of the head, according to the Ludwig and Savin
Scale below.
