Hair loss is a physiological or pathological process of hair loss. Pathological hair loss leads to their uniform deterioration, partial or complete absence in limited areas or total alopecia. The causes of hair loss can be a lack of vitamins and trace elements, side effects of drugs, hormonal and infectious diseases, stress, heredity, improper hair care. Often, eliminating these causes leads to the restoration of the hairline.
Each person loses 50 to 100 hairs each day. Hair lives on the head from 3 to 7 years. 90% of the hair on the head is actively growing, the remaining 10% are at rest. This phase lasts from 2 to 6 months, after which the hair falls out. Usually, with age, hair does not become thinner, but sometimes new hair does not grow on the spot of the fallen hair. This process can begin already in early adulthood. Hair loss can be caused by various diseases, hormonal imbalance, head trauma or head skin damage, stress or the administration of certain drugs. Often the hair starts to grow again when eliminating the cause of the fallout.
Causes of hair loss
The causes of hair loss and hair loss are different, although as a result of both conditions a person loses a significant amount of hair.
- the aging process;
- heredity (bald men and women in the genus);
- hormonal imbalance (for example, in women after childbirth or during menopause);
- damage to hair (staining, drying, chemical perm);
- head injury;
- damage to the scalp;
- bacterial and fungal infections, autoimmune diseases;
- Some medications can cause reversible hair loss (pressure medications, anticoagulants, antidepressants, remedies for arthritis and gout). Radiation and chemotherapy for oncological diseases in 90% of patients causes hair loss.
- birth control pills can also cause more intense hair loss during admission.
- stress: physical, emotional and neuro-psychic.
Other causes of alopecia include:
- Thyroid gland diseases;
- infections, surgical operations, severe fever;
- systemic lupus erythematosus;
- fungal infections (dermatomycosis, ringworm);
- wrong hair (tight braids and tails).
Diagnosis of hair loss
Hair loss does not remain unnoticed. And, if alopecia is observed mainly in men, then problems with hair loss are more often observed in women. An important difference of alopecia from simple hair loss is that in the latter case, the pathology of the hair follicle is not observed.
