  • Alopecia areata

  • Alopecia occurring after a traumatic situation

  • Diffuse alopecia

  • Alopecia, which is based on hereditary factors

Causes of Alopecia

Causes and symptoms of alopecia

The etiology of some forms of diseases is currently not fully known, so alopecia is considered a multifactorial disease.

The cause of focal alopecia can be stressful situations, prolonged intoxication, autoimmune processes. Alopecia can also develop against the background of unfavorable heredity or as a result of a traumatic situation, due to pulling out hair during a fight, game, etc. Alopecia can be caused by pulling (traction) of hair when styling it in a hairstyle. The occurrence of cosmetic alopecia with frequent use of forceps for straightening or twisting hair, the use of hot styling is described.

Alopecia can also be caused by hormonal imbalances. A shift in the balance between androgens and estrogens towards a decrease in the amount of estrogens in the blood can cause the development of the so-called androgenetic alopecia, which, manifesting itself in a mild form in men, is not a cause for concern and is not considered a pathological process. In women, such a violation of the ratio of hormones can be the cause of an increase in the production of androgens by the adrenal glands or ovaries.

Diffuse alopecia can be a consequence of prolonged intoxication, chronic poisoning, and long-term severe infectious diseases. Such a pathology often accompanies the course of pregnancy.

Alopecia can be passed down from generation to generation, in this case they speak of hereditary alopecia. Most often, the type of inheritance is autosomal recessive, but in some cases there is also an autosomal dominant type of transmission of genetic information.

If the cause of alopecia is the destruction of hair follicles due to the appearance of scar tissue on the skin, then such a pathology should be attributed to cicatricial alopecia. Various skin injuries (burns, exposure to radiation), the manifestation of certain infectious diseases – such as syphilis, tuberculosis, leishmaniasis or tumor growth – can cause cicatricial alopecia.

Symptoms of alopecia

Causes and symptoms of alopecia

The main clinical manifestation of alopecia is hair loss. The pathological process can manifest itself in the form of small foci of baldness and in the form of complete baldness. Symptoms of alopecia are directly dependent on the form of the disease.

Alopecia areata is accompanied by focal hair loss, and the foci of alopecia are round or oval in shape. This type of pathology is characterized by an increase in the area of ​​the lesion over time. Hair that is on the border with the focus becomes thinner and dystrophic. Alopecia is often accompanied by vitiligo and onychodystrophy.

After a few weeks or months, new hair may appear in place of the fallen hair, but after a while the grown hair also falls out, after which the foci of the pathological process grow, occupying an even larger area. Alopecia acquires a total character and is accompanied by loss of eyelashes and eyebrows.

Baldness can also begin with a smooth surface of the skin (so-called ophiasis). In this case, the course of the disease is malignant and, as a rule, is accompanied by pathology of the endocrine system, as a result of hypofunction of the thyroid gland or adrenal insufficiency.

Traumatic alopecia also has separate lesions. Areas with a complete absence of hair border on areas of skin covered with whole or damaged (broken) hair; when examining the patient, traces of damage to the skin are also noticeable.

Symptoms of hereditary alopecia are mainly found in children. In this case, the pathology is accompanied by atrophy of the hair follicles in all areas of the skin. The disease may be accompanied by other anomalies and malformations. A characteristic feature of hereditary alopecia is the presence of the disease in several family members.

Androgenetic alopecia has a progressive course. Hair loss in most cases begins with the frontal zone, over time, baldness spreads to the crown of the head.
