Hair Loss due to Hormonal Imbalance
Androgen, Estrogen, Progesterone are the hormones that vary in one’s lifetime according to age and health of a person. Variation or imbalance in their activity may lead to subsequent hair fall.

Menopause is another condition, which leads to Hair Loss.
The Genetics of Hair Loss
To lose hair at young age may be due to hereditary factors and genetics play a major role in determining the quality and strength of hair. Mainly in Men, baldness is genetic. Baldness mostly happens because of the genes people inherit from both their parents. Studies show that 80% of balding is genetic. People are more likely to be bald if their dad or their maternal grandfather is bald.
Two new studies have found a small region on chromosome 20 called 20p11 which is said to be associated with balding. This shows people are bald even though their maternal grandfather still has a full head of hair. Scientists have no clue on how this DNA is involved, but they concluded the people who are bald tend to have a certain version of 20p111)http://www.nature.com/ng/journal/vaop/ncurrent/abs/ng.228.html.
Another study2)http://www.nature.com/ng/journal/vaop/ncurrent/abs/ng.255.html found a different bit of 20p11, and it was found that the risk of becoming bald was as high as 3 times.
