Hypertrichosis is excessive local or widespread hair growth in those areas of the skin where hair should not be. In the special literature one can find synonyms Hypertrichosis (hypertrichosis) - polytrichia, virile syndrome, although many doctors attribute these diseases to different types of one category.
Hypertrichosis is abnormal hair growth in women, in men, and even in children, and virilism can be affected only by female representatives, when the embryo is one of the symptoms, but not the only one.
Hypertrichosis as an androgen dependent phenomenon has various forms and can be caused by several causes, its official classification is as follows:
ICD-10 L68, Hypertrichosis:
- L 68.0 - Hirsutism L 86.1 - Hypertrichosis by cannulated hair acquired
- L 86.2 - Localized hypertrichosis
- L 68.3 - Political Science
- L 68.8 - Other hypertrichosis
- L 68.9 - Hypertrichosis, unspecified
Causes of hypertrichosis
The causes of hypertrichosis depend on its form, which are etiologically defined as follows:
- Congenital hypertrichosis:
- Congenital universal - embryonic.
- Congenital local.
- Acquired hypertrichosis:
- Interblade.
- The pubertal.
- Climacteric.
Generally, the causes of hypertrichosis are caused by genetic factors. As a result of the mutation of epithelial cells, their structure changes, which acquires the properties of the epidermis. In turn, a genetic mutation can be associated with an abnormal process of bearing a fetus, when pregnancy is difficult, and infectious diseases in the first trimester can also cause the transformation of the epithelium. In a newborn, the symptoms of excessive hair loss may not appear, but the potential, latent danger remains: the child can be the bearer of a mutated genome, and hypertrichosis will manifest itself in the next generation.
Unlike the congenital pathological growth of the hairline, acquired hypertrichosis provokes other causes, for example, the constant effect of irritation on the skin, such as shaving, the harmful habit of pulling the hairs, mechanical friction and so on. In addition, hair follicle develops as a consequence of the intake of certain medicinal groups - glucocorticosteroids, both in tablet form and in the external (ointments, creams).
We list the most common factors and causes that trigger hypertrichosis: •
- Congenital genetic pathologies, including anomalies in the development of the bone or mental system, when the embryo is one of the clinical signs of the disease.
- Endocrine pathologies - pituitary, adrenal, ovarian, thyroid.
- Imbalance of the hormonal system (pregnancy).
- Changes in the hormonal system associated with menopause.
- Tumor of the brain, breast, ovary.
- Epilepsy.
- Drug factors - the use of corticosteroids, streptomycin, androgen drugs.
- Metabolic disorders as a result of fasting (anorexia).
- Mechanical irritation - shaving, plucking hair.

How is hypertrichosis inherited?
To date, geneticists have established many congenital types of hypertrichosis, which manifest themselves immediately after the baby's birth. Pushkovoy devotion to the newborn is associated with inheritance, both parents or someone one of them already has a similar problem. Unlike the normal cannon cover of babies, the hypertrichosis is characterized by a thicker, more visible, pigmented hairline. Localized congenital hypertrichosis on the neck, trunk, sometimes on the face (forehead). The pathological congenital hypertrichosis of fetalis lanuginosa is often accompanied by adentia (dystrophy of the teeth), diseases of the nervous system and malformations (oligophrenia, microcephaly). There is also a congenital kind of gun thrush - hypertrichosis congenita, inherited in an autosomal dominant type with a high level of penetrance (the indicator of the genotype).
How is hypertrichosis inherited in an autosomal dominant type?
Types of inheritance can be different. Autosomal dominant is characterized by the fact that the altered (mutant) gene is transformed into an active feature even in a heterozygous form, so the child inherits the altered form of the gene (allele) even during conception from one of its parents. The inheritance of hypertrichosis in the autosomal dominant variant suggests that the likelihood of haemophilia is equal for both newborn boys and girls. Unlike the hypertrichosis of foetalis lanuginosa, this pushkin hypertrichosis does not entail serious consequences for the health of the newborn, and does not affect its mental, physical and reproductive development. The disease associated with excessive hair growth can occur in every generation, the possibility of the situation that a child of "hairy" parents will inherit their feature is equal to 50%. There are other variants of inheritance, when the level of penetrance is low, then the pathological growth of hair may not appear in a newborn. It is also possible to "debut" hair at a later age, for example, in puberty or in menopause in women.
Currently, more than 20 forms of hereditary hypertrichosis are known, local and total, including those with defective genes HTS2, HCG, CGH, X, when the embryo is combined with congenital anomalies of development - fibromatosis of the gums, skeletal dysplasia.
When and how is hypertrichosis inherited, what is the probability of inheritance?
- If the genus has a sufficient number of offspring with inherited hair, hypertrichosis occurs in each generation.
- Women and men inherit hypertrichosis in equal proportions.
- Hereditary hypertrichosis can be transmitted by both mother and father.
- The probability that a child will inherit hypertrichosis, if passed through a generation, is 50%.
Hirsutism and hypertrichosis
Although hirsutism and hypertrichosis belong to the same class in ICD-10, these are different types of hair. The first thing that distinguishes these two anomalies is that only women can suffer from hirsutism, and in most cases it is associated with androgenic factors (male-type haemorrhage), whereas hypertrichosis is polyethiologic and does not know sexual or age barriers. How to distinguish hirsutism from hypertrichosis? First, you need to distinguish between canine and terminal hair. Puff is soft, almost imperceptible hairs, terminal ones are usually dark, hard, long. Briefly, the growth of gun and terminal simultaneously in large numbers in atypical places of the body, as well as in places where it seems to grow, but they grow excessively active - polytrichia (hypertrichosis). Hirsutism often manifests itself in the growth of terminal hair in androgen-sensitive, diagnosed 9 zones.

Thus, hirsutism is a purely female problem of excess hair growth, and hypertrichosis can affect any person, regardless of gender and age, although it should also be differentiated from the national characteristics of some genotypes for which increased hairiness is characteristic.
Symptoms of hypertrichosis
Signs of hairiness do not need a specific and detailed description, the symptoms of hypertrichosis, as they say, are visible to the naked eye. They can manifest themselves in both men and women, but if for the first the excessive hairiness is to some extent a certain symbol of muscularity, then for beautiful ladies it is a problem, if not a tragedy of all life.
Symptoms of hypertrichosis in women:
- Increased hair growth on the chin.
- Hemophilia nasolabial folds.
- The growth of the hair on the chest, in the area of the mammary glands - the pre-intestinal (anteroplegia) in combination with the dented, sagging sternum. Symptom may indicate neurofibromatosis.
- Excessive hairiness of the legs and hands.
- The growth of the hair in the lumbar region in combination with the spinal cord (spinal pathology). The hair in the region of the sacrum grows in the form of a bundle, which is also called the "bundle of the faun".
- Hewing of the buttocks.
- Haemorrhage pubis by the male type.
- Excessive hair growth can be accompanied by weakness of the limbs, loss of sensitivity.
- Excessive growth of the eyebrows (fusion).
- Birthmarks with tufts of hair, nevi's hair, including Becker's giant melanosis. Pigmentary giant nevus in 80% is accompanied by congenital anomalies - adentia, hip dislocation (spina bifida).
In turn, hypertrichosis can also be a signal of dangerous diseases. Haemorrhage, appearing in adulthood in 90% of cases indicates a hidden oncological processes, dermatomycosis, undiagnosed craniocerebral trauma.
It should be noted that Hypertrichosis can be classified into the following categories:
- Heterochronia is a pituitary abnormality, when secondary sexual signs in the form of excessive hair growth (beard, mustache, pubic hair and so on) appear prematurely in children.
- Heterotopy is a rare congenital syndrome caused by intrauterine diseases, developmental anomalies. When heterotopy in the child, the hairiness acquires a total character, often combined with a congenital dislocation of the thigh, adentia.
- Heterogeny is a male-type hair that belongs to hirsutism. Although hirsutism is considered an independent pathology, it is classified as a type of hypertrichosis.
Hypertrichosis in women
Hypertrichosis in women is most often associated with the hormonal factor and age periods:
- Excessive hair growth can "start" in the puberty period. Hypertrichosis in women is most often manifested for the first time at this age, the age boundaries are quite wide from 7 to 15 years. Hair is localized in the area of the mammary glands, on the neck, back, on the face, in the region of the sacrum, waist. The so-called hypertrichosis pubertalis verginum is a sign of hormonal adjustment, but it can also be a signal of a more serious condition - tuberculosis, diseases of the ovaries, adrenal glands. The diagnosis is rather difficult due to the nonspecificity of hypertrichosis as a secondary symptom.
- Hypertrichosis of young women in the age of 16 to 22-24 years, when increased activity is manifested specifically in gun, rather than terminal hair. They are localized on the legs (shin), abdomen, hips, less often in the chest area. This may be due to abnormal work of the adrenal gland, thyroid or ovaries.
- Hypertrichosis climacteria is a fairly common phenomenon that accompanies the climacteric period. Hypertrichosis in women aged 45 years is most often manifested on the face - the hair grows on the chin, above the upper lip (antennae). After the end of menopause, hair salad can survive and even intensify, which serves as a symptom of insufficient function of the endocrine system.
In addition, it is worth mentioning androgen-dependent syndrome - virilism. The disease clearly corresponds to its name - virilis means masculine. Masculinization of beautiful women can be associated with various reasons, but it is obvious that the main role in them is imbalance of hormones. Excessive production of testosterone as an androgen hormone leads to a syndrome of hyperandrogenism. In this process, the ovaries and adrenal glands are directly involved, less often virilism is provoked by metabolic imbalance when taking steroid drugs (anabolic drugs). Hyperandrogenic syndrome can be of a functional nature, and also be associated with a tumor process. Functional virilism is a violation of the adrenal cortex, as a rule, in the case of Itenko-Cushing's disease (hypercorticism). One of the symptoms of this pathology is hypertrichosis. In addition to hairiness, the woman's voice changes, the body type gradually changes (according to the male type), the monthly cycle stops, the size of the mammary glands changes to the smaller side.
Also excessive hair growth can be triggered by pathological fasting, anorexia. Against the backdrop of an extreme degree of exhaustion, a woman can develop a pulmonary embolism, which gradually disappears during the therapeutic period as she recovers.
Hypertrichosis in children
In childhood, hair is usually congenital. Abnormal hypertrichosis in children is very rare - only one child per billion newborns. Pushkin hair, which should have disappeared in the womb of the mother, remain, they can be seen literally from the first minute of birth. The hair is rather dark, thick, dense, which is not typical for infant hair follicles - lanugo. Generalized hypertrichosis in children is an unpleasant sight, the whole body of the baby is covered with hair. Often hypertrichosis fetalis is one of the symptoms of severe congenital malformations - adentia, abnormal structure of the cranium (microcephaly), a violation of mental functions. It is believed that primary pathological hypertrichosis in children is genetically conditioned in 100% of cases.
Also, atypical hairiness can be inherited, but not abnormal, this happens when both parents of a child suffer from hypertrichosis, or someone is one of them. For example, supercilia confluentia - thick, almost fused eyebrows, however, this sign can signal a dementia, a delay in mental development.
In addition, hair can develop on nevuses (verruk, cellulary, pigmented), with pathological syndromes - Scheffer, Recklinghausen.
The pathological hairiness of a child can be provoked by a negligent mother, an extensive hypertrichosis in 10-15% is found in children born to women suffering from chronic alcoholism. In addition to hair growth, these babies also have defects in skeletal formation and 8-10% have mental retardation.
Hypertrichosis in men
According to statistics, hypertrichosis is a typical female disease, among seven women there is only one man with pathological hair. As a rule, hypertrichosis in men manifests itself at the age of 10 to 14 years, if not a congenital form.
Hypertrichosis in men calls excessive hair in zones where hair in principle grows and should, but not in such quantity, even taking into account age and nationality. For example, the growth of hair on the male breast should not cause surprise, it is considered normal, but if the hairline is more like a wool and provokes the surrounding issues, and the owner of the head of hair complexes, it's time to go to a doctor or a cosmetologist.
Increased hair growth can be both congenital and acquired, this applies not only to men, but also to women. Congenital hypertrichosis is seen from the first days of birth and is likely to be a hereditary trait. Acquired hair can be associated with craniocerebral trauma, the use of anabolic steroid drugs, mechanical or medicamental factors (shaving, rubbing hormonal ointments, taking certain medications). In addition, excessive hair growth is often associated with the national genotype, it is known that in Caucasians, Arab countries, Jews, Italians, hair growth is much faster than the "hairiness" of representatives of other countries and is not considered an anomaly.
In addition to the above reasons, hypertrichosis in men can provoke hypergonadism, that is, earlier puberty caused by an elevated level of androgens. Secondary sexual characteristics begin to appear in boys aged 8-10 years, including hairiness, more typical for adolescents aged 14-16 years.
Also, excessive hair growth causes such diseases, which are worth knowing about and paying attention to hypertrichosis, if it develops in adulthood for the first time:
- Tumor process.
- Diabetes mellitus (hypertrichosis diabetica) - hair on the back in the area of scapula and on the abdomen near the navel.
- Encephalopathy.
- Tuberculosis.
- Alcoholism.
- Hidden undiagnosed craniocerebral injury.
Congenital hypertrichosis
True congenital hypertrichosis is rare, the symptoms of gun fluence are visible right after birth and do not disappear on their own throughout their lives. One of the types of congenital hypertrichosis is lanuginous hair, from lanugo it is a hair. Lanugo normally covers the entire fetus, starting from the 27-28th week of pregnancy, to 40-1 weeks of hair disappear. In case of a genetic abnormality, a child is born with excess cannon hair, often accompanied by concomitant congenital pathologies. Congenital hypertrichosis can be local, that is, the hairs grow on certain parts of the body - the back, waist, face, forehead, and also the hair can be generalized, that is, cover the entire body. A bunch of hair in the area of the sacrum (fascian bundle) is a sign of a spinal pathology - the non-vertebral arches (bifid spin).
Congenital hypertrichosis is classified as follows:
- hypertrichosis congenita is a universal congenital hypertrichosis in an autosomal dominant type.
- hypertrichosis fetalis - embryonic hypertrichosis, which is combined with other congenital pathologies.
- hypertrichosis congenita localisata - local lumbosacral hypertrichosis or pigmentary hair nevus (fascian bundle).
The most favorable in terms of predicting the future development and quality of life - a universal congenital hypertrichosis.

Pushkin hypertrichosis
Hypertrichosis lanuginosa is an inherited or acquired disease. The genetic factor provoking pulmonary embolism is a rather rare clinical case, more often the pushrokinic hypertrichosis is caused by external or internal causes, that is, this form of acquired hair.
The congenital form of gun hypertrichosis is so rare that it is more known from historical documents than from real documents. Since the first description of the "werewolf" 400 years ago, only about 50 diseases have been diagnosed so far. The genetic anomaly has territorial preferences - northern Romania (Transylvania), Indian states, South America.
Hitherto, the process of dominating a mutant gene is a mystery, its expressiveness can not be studied due to the small number of clinical observations and their length over time. In all likelihood, the true gun congenital Hypertrichosis is the echoes of atavistic mutations, which are less and less common every century.
Acquired hypertrichosis has been studied fairly well and extensively. It should be noted that the syndrome of cannula hair, which begins to grow suddenly, in a person who previously did not suffer from excessive hair growth, in 80-90% is a sign of latent oncopathology. 98% of all detected tumors are malignant, it can be oncology in the lungs, in the bladder, in the gastrointestinal tract, and breast cancer, uterus, is often determined.
Diagnosis of pulmonary embolism is difficult enough, the diagnosis should be differential. Difficulties are associated with nonspecific symptom in contrast to hirsutism, where there are clear diagnostic criteria. Preventing Pushkin hypertrichosis is impossible, the only thing that can be done in the case of a universal hairlessness that does not have pathological factors, is the correct hair removal. Treatment of hypertrichosis in this case should be carefully thought out, since any cicatricial changes after epilation procedures, trauma to the skin, can activate hair growth.
Werewolf Syndrome and Hypertrichosis
Legends of Transylvanian werewolves, vampires and other evil spirits, generated a lot of rumors and superstitions. Today, what was previously apparently thought to be the product of Dracula, is called either generalized hypertrichosis, or erotopoietic porphyria, which is also accompanied by excessive hairiness. Along with such rare diseases as progeria, Alice's syndrome and other curiosities, werewolf syndrome, hypertrichosis is still among the ten most strange and unique diseases. According to statistics, true pathological hairiness occurs in the ratio of 1 case per billion. More recently, geneticists have identified one possible cause of the mutation of the autosomal gene. Scientists have tracked a whole generation of the Mexican family, beginning in 1995, and determined that the responsibility for hypertrichosis bears the X chromosome, there was an excessive number of genes (alleles SOX3). And in the men of this family, the hair grew on the face and in the eye area, and the women got more unpleasant symptoms, the hair was grown all over the body. This discovery does not help those who suffer from werewolf syndrome, but in the foreseeable future it is possible to solve the problems of alopecia and alopecia.
Hypertrichosis of the auricle
Hairizing the edge of the auricle is not a pathology in principle, it is quite common in men with an elevated level of androgens. Such vegetation appears in the nostrils, so the problem is solved simply - depilation or hair removal for the choice of the owner of hair. Hypertrichosis of the auricle is usually due to a genetic factor and is inherited as a sign attached to the Y chromosome. Auricle can develop from the age of 16-18 when the pubertal period ends and the hormonal system returns to normal, but more often hypertrichosis in this zone "starts" after 35-40 years or later. Often, when hereditary alopecia accompanied by compensatory hair growth in the nostrils and in the ears, it is also associated with a genetic factor, and not pathology. In women, the auricles remain normal, hair growth in this zone practically does not occur, in single cases, there may be male-type hair in the viral syndrome. Other causes of genetics and biologists have not yet been found, because in normal microscopic hairs, the fluff covers the ears of all people without exception.
Treatment of hypertrichosis
Before determining tactics and strategy of actions, hypertrichosis is diagnosed and classified, and this will determine its treatment. The examination should be carried out by an endocrinologist, urologist or gynecologist, possibly a dermatologist. First of all, they exclude a possible menacing pathology, since often pulmonary hypertrichosis is a sign of oncological processes in the body.
Treatment of hypertrichosis is carried out according to diagnostic findings, but most often the first stage is the elimination of a cosmetic, visible defect. This is especially effective in the congenital form of the disease, which, except as a symptomatic, is not treated differently. In addition, if a hormonal cause is identified, adequate hormone replacement therapy is performed. If hypertrichosis is caused by a medicamental factor, the provoking hair is excluded, if the course of therapy is necessary, the medicine is replaced with a more sparing and without side effects.
Modern dermatocosmetology has many tools and methods that help to solve the problem of hypertrichosis, of course, provided that it is not a sign of a serious pathology. Perhaps in the near future, geneticists will still find the true cause of gene mutations and will be able to offer a truly effective way to get rid of pathological hair loss.
How to treat hypertrichosis?
In order to answer the question of how to treat hypertrichosis, it is necessary to find out its true cause, which is sometimes difficult to do.
If abnormal hair is diagnosed in a child having parents with excessive hair growth, treatment can only be symptomatic, since no gene mutations have so far been able to become or even neutralize anyone in the world.
If hypertrichosis is caused by dysfunction of the endocrine glands, treatment is adequately diagnosed, that is, therapy should be directed at curing the condition of the ovaries, adrenal glands, thyroid gland and so on. How to treat hypertrichosis in this case is decided by a gynecologist-endocrinologist or a urologist-andrologist for men.
In addition, it is important to stabilize the patient's neuropsychiatric condition, since the embryos are sometimes a whole tragedy, especially for women.
Localized hair can be given to the physiotherapeutic method - electrocoagulation, it is possible to depilate, but it must be performed with the help of a dermatologist, and not in a beauty salon. Depilation done alone can only do harm, since traumatic skin damage is unavoidable, and even small doses can provoke and activate new hair growth. Strangely enough, but the old and traditional way - shaving, in this sense, the safest method of self-removal of excess hair, especially if you do it with an electric shaver.
Treatment of hypertrichosis by alternative means
There are many so-called alternative methods of hair removal. Perhaps they are effective when it comes to simple epilation. In the case of pathological hair, this is fraught with complications, so treatment of hypertrichosis by alternative methods should be done only with the consent and on the recommendation of the attending physician. This particularly applies to the facial area, as well as hypertrichosis caused by endocrine disorders, adrenal gland pathology or pituitary gland.
In this connection, the only thing that can be recommended is relatively safe vegetable dips and decoctions, which are used inside, with long courses. Such alternative recipes help to adjust the work of the hormonal system, strengthen nerves, improve the overall condition. Other methods used externally as epilating, not only are not given in the framework of this article, but are not recommended in principle.
- Decoction of St. John's Wort for Women. St. John's Wort is recommended for normalizing the hormonal background, treating the nervous system, as a restorative. The course of reception of broth should not exceed 14 days, then a month break is made and the course can be repeated. 1 tablespoon of dry herbs brewed half a liter of boiling water, infused for not more than 5 minutes. The broth is filtered, divided into 2 parts, which are drunk individually in the morning after breakfast in 40 minutes and before going to bed.
- Decoction of licorice for men. Lakrichnik normalizes the work of the hormonal system, acts as a restorative male body. 1 teaspoon brewed a glass of boiled water, insist 15 minutes, filter, drink 1 time a day for 21 days. Then you need a two-week break, after which the course is repeated.
- Infusion of clover. Avicenna also used his patients' decoction of this amazing plant. Clover helps to improve the work of the genitourinary system in men, cleanses the blood, restores strength. 2 tablespoons dry grass (flowers, stems) pour in a liter of boiling water in a thermos. Insists a decoction of 12 hours, it is convenient to do this from the evening. In the morning the broth is filtered and drunk half the glass 3 times a day for half an hour before a meal. The course is a month, then the break and treatment is repeated.
- Etheric little geranium for women. Geranium contributes to the activation of estrogen production, its essential oil has long been used by women in the northern territories of Africa. Pelargonium helps to cope with depression, restores skin turgor, normalizes the nervous system. In warm water add 7-10 drops of essential oil, take a bath for 15-20 minutes, no more. Such procedures are recommended twice a week for 2-3 months.
In addition to decoctions and bath procedures, acupuncture can help as an auxiliary, but it should be decided by a dermatologist, endocrinologist, in a word, a doctor in charge.
Self-treatment with hypertrichosis is fraught with at least increased hair growth, as a maximum - complications of the internal organs.
Treatment of hypertrichosis in women
For women, the problem of pathological hair loss is not just a problem, it is a provoking factor of depressive conditions and other nervous diseases. Therefore, if excess hair growth is not associated with gynecological, endocrine diseases, especially treatment of hypertrichosis in women, this is a careful, correct hair removal. The therapeutic course is selected strictly individually, before treatment is mandatory is an additional consultation with a narrow specialist - dermatologist, endocrinologist, and possibly an oncologist. It's no secret that the gun-derived hypertrichosis in most cases indicates a hidden cancer, so once again think about what is more important - health or hair removal.
That is categorically contraindicated in hypertrichosis:
- Local paraffin applications.
- Wax depilation.
- Ointments and creams containing mercury.
- Scrubs.
- Ultraviolet irradiation
- Massage.
- X-ray irradiation.
- Mechanical methods of epilation - pumice, plucking.
- Hormonal creams, ointments.
What can help?
- Temporary depilation with depilatory cream.
- Bleaching of hair from magnesium carbonate and hydrogen peroxide. 10 grams of magnesium are mixed with 20 ml of peroxide, neutral liquid soap is added, the mixture is applied to the hair and left for 25 minutes.
- Electrophoresis with the addition of lidase.
- Electrolysis.
Hypertrichosis is a complex anomaly, the causes of which can be related both to a hereditary factor and to diseases of internal organs. No matter how thick and thick the hair grows, you need to examine the body, find out the true cause and entrust the treatment to specialists before they are eliminated.
