What is hypertrichosis?

Hypertrichosis is excessive hair growth. Hair - derivatives of the epidermis of the skin of mammals and man, whose roots lie deep in the skin. In humans, up to 8 months fetal development the body is covered by primary or fetal hair, hair by the time of birth are only on the head, eyebrows, eyelashes. Replacement of primary secondary hair ends, usually after birth. There are three types of human hair: long - it's the hair of the scalp, armpits and genitals, and the mustache and beard for men, bristly hair, short, relatively hard, they are treated hair eyebrows, eyelashes, nostrils and the outer parts of the auditory passes; vellus - usually short, soft, colorless, covering almost the entire skin of a person, except the palms, soles, etc. Sometimes there is a violation of the hair growth. At the same embryonic hair can not be replaced by vellus, and continue to grow, covering the entire body. It is also possible the growth of hair in those places where they are not usually the case, for example, beard growth in women.

Symptoms of hypertrichosis

  • The growth of hair on chest, rump, cheeks, and the irritated areas of skin moles in women.
  • Intensive growth of eyebrows, eyelashes and pubic hair.
  • Beard growth in women.
  • Sometimes the whole body covered with hair like wool.

Causes of hypertrichosis

Causes of hypertrichosis may be different: genetic predisposition, diseases of various organs or glands that produce male sex hormones. Excessive growth of androgen-dependent hair in women is hirsutism. Hypertrichosis - a symptom of the onset of female secondary male sex characteristics. The reason for the appearance of large amounts of hair in the sacral region may be a latent defect of the spine: incomplete closure of the spinal canal. Hypertrichosis may occur due to prolonged irritation of the skin during menopause in women, but also as a result of constant use of androgenic drugs, steroid hormones (eg, hormonal contraceptive pills containing progestogen) or with increasing concentrations of adrenocorticotropic hormone (ACTH) in the blood. Possible causes of hypertrichosis may be anti-epileptic drugs and some antibiotics.

Treatment of hypertrichosis

Hypertrichosis

First of all you must find and eliminate the cause of hypertrichosis (in congenital hypertrichosis is not possible). If the excessive hair growth is caused by drugs and hormones, then after stopping their use of hair growth is usually normal. But mostly, these drugs are appointed in connection with serious illnesses, so rejection of them is impossible. This problem occurs if the hypertrichosis is a consequence of any organic disease. In this case, hair growth can be stopped only by destroying the hair follicle.

Most can be treated only the symptoms of hypertrichosis (getting rid of unwanted hair by waxing them, shaving, etc.).

When the hair is not specific to this body area should see a doctor, it is better to a dermatologist.

The doctor carefully examines the affected area of the patient, find out what drugs and hormones takes patient. In addition, the doctor will ask about the presence of hypertrichosis among close relatives. To determine the cause of hypertrichosis physician examines the performance of hormonal metabolism. If treatment is not possible, the doctor will remove the hair by coagulation, which is used only in severe cases. It is generally recommended to use depilatories.

This is a benign but rather an unpleasant skin disease. It periodically increases, although it may disappear.

In rare cases, a danger to the patient may present complications caused by digestive disorders.
