Causes of Excessive Hair
Heredity
A genetic predisposition can result in excessive hair growth.
Glandular
Sometimes the glands that make up our endocrine system (the system that controls our growth and development) become imbalanced. This imbalance can result in excess hair. There are certain medications which may also contribute to excessive hair growth, such as male hormones and birth control pills.
Normal
Normal growth and development bring about a change in hair growth, i.e. puberty, pregnancy and menopause. Stress and illness may also be a factor.
