Hair is usually unwanted on most of the body parts. An increase in the amount of hair is known as Hypertrichosis.
Hirsutism is a condition which manifests due to a hormonal imbalance which leads to an increase in the circulating androgens. This causes excessive hair growth in different parts of the body.
Virilization is a combination of signs and symptoms which include hirsutism (excessive hair growth), acne, androgenetic alopecia (hair loss), menstrual irregularities and other symptoms. An excess of androgens plays an important role in all the manifestations.
The different causes of hormonal imbalance can be due to polycystic ovary syndrome, idiopathic or due to racial or hereditary variations. Excessive hair growth or hirsutism is usually seen in 9 different body areas:
Upper and Lower Back
Upper and Lower Abdomen
The grading is usually done by the modified Ferriman-Gallwey Scoring system. Each part is assigned from 0 (no hair) to 4 (frank growth). A score of 8-15 is usually mild. A score greater than 15 requires medical intervention.
