female beard causes of female excessive hair growth hirsutism hirsut

All females grow body hair! No news there! However, the vast majority of ladies have normal quantities of body hair. However, many ladies will suffer from female excessive hair growth.  Excessive hair growth is otherwise known as hirsutism. 

People of all genders will start to grow body hair from puberty. Sometimes there is no obvious underlying cause of female excessive hair growth. However, there are several relatively common medical conditions that may cause facial hair or body hair to grow.  This hair may be removed by cosmetic laser hair removal for aesthetic benefit. It may be important to learn the exact cause of the unusual hair growth.

Medical Causes of Female Excessive Hair Growth

Polycystic Ovary Syndrome (PCOS)

Polycystic Ovarian Syndrome (PCOS) causes a creation and release of an high level of androgens. What are some common signs of PCOS? Symptoms include hirsutism (excess hair growth), acne, irregular periods or absent periods (amenorrhea).  PCOS is the most prevalent cause of excessive body hair in people born female. It is estimated that in excess of two thirds of all cases of hirsutism PCOS is the primary cause. 

You’re also more likely to develop hirsutism if you’re of a Mediterranean, Hispanic, South Asian or Middle Eastern background.

Hirsutism rarely affects children. If it does, it’s typically a sign of early onset puberty.

Issues with your Thyroid Gland

Your thyroid gland produces hormones that help to control your body temperature and metabolism. Hyperthyroidism (over active thyroid) and hypothyroidism (under active thyroid) are the two most prevalent thyroid disorders.

The thyroid gland produces hormones that regulate the body’s metabolic rate controlling heart, muscle and digestive function, brain development and bone maintenance.

It is quite rare, but an issue with your thyroid gland can result in excessive body hair growth.


In rare instances, a thyroid disorder may result in a hormonal imbalance that promotes the growth of excessive body hair.

Medicine as a Cause of  Excess Hair Growth

Some prescription medicine may increase hair growth. After starting a new prescription medicine, you should notify your doctor if you see unusual, or excessive, hair growth.

Among the types of prescription medicine that has been linked to development of hirsutism as a side effect are:

  • some antipsychotic medications

  • glucocorticosteroids

  • some anti-seizure drugs

  • some immunosuppressive drugs

  • hormone treatments, including testosterone, as well as certain medications that alter natural hormone production in your body.

Congenital Adrenal Hyperplasia

Congenital adrenal hyperplasia may damage the adrenal glands and can result in severe symptoms.

When the adrenal glands are not functioning properly, the female body may produce an excessive amount of androgens. Girls may demonstrate symptoms including abnormal or absent periods, a deep voice, early puberty and facial hair.

Adrenal hyperplasia-causing disorders must be screened for by medical doctors. However, it can often take till puberty to diagnose minor cases.

Laser Hair Removal to treat Hirsutism

During laser hair removal treatment heat from a cosmetic laser destroys cells that have a lot of pigment (color). Dark hair has a lot of pigment, so it absorbs the most heat. Hair transfers heat to the hair follicles and destroys them, so hair can’t grow. The only hair colour that cannot benefit from laser hair removal is auburn hair (redheads or ginger hair) or those people with naturally very light blonde hair.

Uncommon side effects may include blisters, burns, scars, dark areas of skin and light areas of skin.  However, whilst we always explain this before every treatment, these side effects are very rare. If they were not rare we would not be as busy as we are with very hapy clients!
