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.
