All women have hair on their faces and body but it is usually fine and light in colour. There are many reasons why a woman may experience excessive facial hair growth, as well as over other parts of her body. In the majority of cases the cause is changes in hormonal balance which can be experienced during puberty, pregnancy, after the menopause or if a woman suffers with Polycystic Ovary Syndrome (PCOS). Other causes can be:-
Excessive hair growth in areas in which men usually grown hair usually indicates the presence of excessive male hormones (androgens), or an increased sensitivity to them. This condition is called hirsutism. All women produce a small amount of the male hormone testosterone, but higher than normal levels may increase your sex drive, effect your menstrual cycle and produce excessive facial or body hair.
Pregnancy – During pregnancy the levels of testosterone in the blood rise which may lead to increase hair growth. After the baby’s birth, testosterone levels will return to normal and you should notice hair growth returning to normal.
Polycystic Ovary Syndrome (PCOS) – PCOS is the most common cause of hirsutism in younger women. Benign cysts form on the ovaries which can affect hormone production. This will often lead to excessive hair growth as well as irregular peroids, infertility, weight gain and acne.
Tumours – Tumours affecting the adrenal or pituitary glands and some tumours of the lungs, ovaries or digestive tract can increase the production of male hormones. If you are not already aware of suffering with a tumour, but notice a sudden growth of hair, consult your GP.
Medicines – some medicines such as anabolic steroids, minoxidil (for high blood pressure) and the contraceptive pill can affect your hormone levels, resulting in excessive hair growth.
Some cases of hirsutism are genetic with women from certain ethnic groups being more prone to excessive hair growth which starts from puberty and has a slow progression.
If you experience a sudden growth of excess hair, a deepening voice, absence of menstrual periods or are concerned about increased hair growth, make an appointment to see your GP so that any causes, hormonal or otherwise, can be investigated and dealt with.
Your GP is likely to ask you questions about circumstances and extent of excessive hair growth you are experiencing and will examine the areas of concern. You will be asked about the pattern and speed of growth, as well as when you noticed any changes. The GP will run tests to check your hormone levels. If they are high in androgens, they may send you for an ultrasound to check your ovaries or a CT scan to check your adrenal gland. These tests can show if you have any tumours.
There are a number of treatments you may want to consider:-
If any of the above treatments aren’t suitable, don’t work or adequately treat the problem, your GP is likely to refer you to a specialist.
