Malattie che causano la perdita di capelli

Hair diseases are common in men and women. The problem is prevalent throughout the world. There are several factors responsible for hair loss. The causes of hair loss diseases may vary from person to person.

The factors that cause hair loss is genetic disorder, malnutrition, stress, certain medications and hormonal imbalance. One of the causes of hair loss is hormonal imbalance and can cause baldness, a major illness causing hair loss of hair.

Common diseases of hair

Common diseases causing hair hair loss include the following:

Baldness -also known as pattern baldness, hair loss/model is a problem of hair common in males and females in the world. The medical term for the problem is the androgenetic alopecia.

Among men, the disease causes hair loss in a well-defined pattern. Begins above both temples, and ultimately the hairline recedes to form a characteristic "M" shape. Hair loss is also assisted by the Crown (near the top of the head).

Among women, the disease causes thinning hair all over his head. However, the hair will not recede. Total baldness caused by androgenetic alopecia is rare among women.

The disease is likely to be caused by a number of genetic and environmental factors. A particular group of hormones called androgens is linked to this problem. Especially a particular androgen hormone called dihydrotestosterone (DHT) is the main cause of this problem. Increasing the concentration of DHT causes changes in dynamics of growth of hair and scalp and baldness.

Hypotrichosis -refers to the condition where there was never any hair growth. It differs from the situation where there is loss of hair in a place once you have hair. In the affected area is hypotrichosis completely bald for the right to life from birth.

The General causes of hypotrichosis are genetic or chromosomal defects in embryonic development. Common forms of hypotrichosis are aplasia cutis congenita, triangular alopecia and congenital atrichia.

Alopecia areata -Alopecia areata is another prominent member of the hair loss diseases. This autoimmune skin disease is highly unpredictable in nature and affects not only the scalp, but also other hair growing areas of the body. All without distinction as to sex and age is vulnerable to this disease.

In alopecia areata the person's immune system (white blood cells), erroneously, affected hair follicles. The result and the end of the hair growth phase. The problem starts with one or more small, round, smooth bald patches on the scalp. Then slowly affects the scalp.

The problem is called alopecia totalis when covers the entire scalp and it is called alopecia universalis when it affects the whole body.

Seborrhoeic dermatitis -is basically a problem of skin. However, it can also cause temporary hair loss. The problem is defined as ' cup cradle of the infant. But it is only during puberty that the condition becomes apparent.

The problem is usually found among young people. It is rare in middle age. But once again became common among 50 more people.

It is more common in men than in women. It is known that Seborrheic Dermatitis is unusually high among AIDS patients. Apparently, the problem is caused by a genetic component. A cause of contention is the yeast Malassezia species. Changes in humidity or seasonal changes also commonly worsen the disease.

Telogen effluvium (TE) -this condition of abnormal hair loss is caused by alteration of hair growth cycle. The alteration can be caused by various factors. The disease causes a higher proportion of hairs entering resting phase of the cycle and the shedding of hair is more than normal.

The person concerned is suffering from diffuse thinning of hair on the scalp. Thinning is not uniform. Rather it is more serious in some areas than others. Usually the scalp hair thins more than it does to the sides and back. Usually the hair back, except in some rare cases of chronic telogen effluvium.

Chronic telogen effluvium affects other hair bearing areas of the body as the eyebrows and pubic hair. Regardless of the pattern of hair loss, telogen efflivium is fully reversible, as hair follicles are not interested in permanently.

General causes of hair loss include vaccinations, physical trauma, recruitment of medicine and surgery. This problem may also cause hormonal imbalance. Inadequate diet can also activate telogen effluvium. For example, a reduced intake of red meat (source iron key) should be a cause of this disease.

Stress also plays a crucial role in stress. In some cases, sudden intense depression and anxiety can also cause hair loss.
