First of all excessive hair growth in females is mainly due to Polycystic Ovarian Syndrome (PCOS).

Most of the doctors have evaluated the common cause of “Hirsutism” in women is Polycystic Ovarian Syndrome (PCOS) which we will discuss in detail further.

Before heading towards the main Hirsutism causes, we should consider some various important aspects of Hirsutism which can lead to some important assumptions and conclusions.

Hirsutism can be divided into two parts that is:

  • Extreme Hirsute:  Some women who are suffering from hairiness problem come into this category. They usually have normal level of male hormones and are also called Idiopathic Hirsutism.
  • Light Hirsute: The women having very less hairs on their body falls into this category which is very common among most of the women.


1. Polycystic Ovary Syndrome/PCOS

Polycystic Ovary Syndrome is the most common Hirsutism cause. It is defined as a hyperandrogenism in association with irregular menstruation. PCOS may begin shortly after the puberty age then teen and early age of adulthood.

In this women hormone becomes imbalance and causes unwanted changes into their appearance. Facial hair is the symptom of this hormone change. 

As a result of PCOS hormones start imbalance which causes Hirsutism in women.

It is often associates with the obesity and acne. If it is not treated timely then it can also cause diseases like diabetes and heart disease. PCOS women are at particular risk for hypertension, hyperlipidemia, diabetes, and possibly coronary artery disease.

Other than Hirsutism PCOS can also cause:

  • Weight gain/obesity
  • Fatigue
  •  Thinning hair on the head.
  • Infertility
  •  Acne
  •  Mood changes
  •  Pelvic pain
  • Headaches
  • Sleep problems


2. Defects in the enzymes

Enzymes are very essential element of human life. It is this which is responsible for all the activities that happen in our body. The enzymatic defect produced by adrenal glands causes the more male sex hormones (testosterone) are produced in girls/women.



Women start gaining the various characteristics of male hormones. One of the most common enzyme defects in adrenal disorders is Congenital Adrenal Hyperplasia. 

As a result of defects in enzymes women starts gaining excessive hair growth on face and body.


3. Ovarian and Adrenal tumor

In contrast to PCOS, the rare group of ovarian and adrenal tumours function independently LH and FSH levels are often suppressed to or below the lower limit of normal.

While circulating androgen levels may be twice the upper limit of normal or higher. Onset of hirsutism or virilization is often unexpected and substantial.


4. Cushing’s Syndrome

Cushing syndrome is a sign of very long exposure of cortisol. Cortisol is a steroid hormone. It liberate in counter of high level of stress and low blood glucose concentration.

It basically falls in the glucocorticoid class of hormones. Cushing syndrome may include high blood pressure. Some of signs are abdominal obesity having big stomach but thin arms and legs.

It may also include reddish stretch marks, a fat lump between the shoulders. It can also lead to abnormal weak muscles, weak bones, breakouts, and sensitive skin.

Women may have more facial hair and irregular menstruation. Sometimes mood swings, headaches, and a chronic persistent feeling of tiredness.

While many women know Cushing’s syndrome at very late stage, at a result gains excessive hair growth. 


5. Idiopathic Hirsutism

Hirsutism is found with regular periods and also has normal androgen levels is known as Idiopathic HirsutismIdiopathic Hirsutism may be due to increased sensitivity to androgens in the pilosebaceous unit.

Due to increased sensitivity to androgen hormone many women have this problem of “Idiopathic Hirsutism”.

A genetic increase in 5α-reductase activity leads to increased synthesis of the potent intracellular androgen di-hydrotestosterone.

A typical example is the familial Hirsutism that often affects women of Mediterranean or East Indian origin. It is usually persistent and may be a temperate variation of PCOS. A gradual increased growth of rough facial hair is typically the only symptom in women with this condition. Menstrual cycles are normal in women with Idiopathic Hirsutism.


6. Increased Sensitivity

Just under a quarter of premenopausal women with Hirsutismhave normal androgen levels. It is thought that if your androgen levels are normal.

There are chances that Hirsutism may be or can be caused by increased level of androgens.

This means that although you have the same amount of these hormones, you are extra sensitive to them and they have a more effect on your body.


7. Ethnic and Racial

Hirsutism can also be genetic and passed from parent to child. There is no extra any hormones changes in the body.

There is no underlying medical condition causing the excess hair, and this term is known as ethnic hypertrichosis.


8. Certain Drugs

  • Minoxidil
  •  Cyclosporine
  •  Phenytoin
  •  Anabolicsteroids
  •  Diazoxide
  •  Progestin-containing medications


In Conclusion – Hirsutism Causes (Top 8 reasons of Excessive Hair Growth in Women)

Hence we concluded that Hirsutism is mainly caused by hormonal disorders like Polycystic Ovary Syndrome (PCOS) which causes Hirsutism. So, these are main “Hirsutism causes” which are responsible for Hirstusim.
