One of the most insidious enemies of hair isdandruff . It causes concern to many. Dandruff is characterized by the appearance of many loose scales on the skin of the scalp, more in the occipito-parietal region. Most often, it is a companion of seborrhea, but may be associated with a violation of metabolic processes in the body, improper hair care. Some scientists view dandruff as an infectious disease.
Skin cells, including the head, are renewed after 28 days, the old ones remain on the skin plane as dead keratinized scales. Usually dandruff is invisible, however, the use of unsuitable and low-quality shampoos, frequent drying and styling with a hair dryer, as well as stress and disease lead to excessive cell renewal and, accordingly, to the appearance of a large amount of dandruff.
Dandruff causes a lot of anxiety not only for women, but also for men. Experts believe that every third person suffers from this scourge. Among the causes of dandruff: nervous strain, lack of vitamins A and group B, improper hair care, overdrying of the scalp, violation of the gastrointestinal tract.
Small flaky flakes of dry dandruff are located along the entire plane of the scalp or mainly in the frontal and parietal regions. Sebum secretion is reduced, itching bothers, gradually the hair becomes dry, brittle and falls out intensively.
If dandruff occurs against the background of increased sebum secretion, characteristic of a disease such as seborrhea, the scales are saturated with the secretion of the sebaceous glands, become layered, yellowish, the hair quickly gets dirty and sticky, becomes greasy, unpleasantly shiny, and itching often occurs. This is due to the fact that fat clogs the ducts of the sebaceous and sweat glands and irritates the nerve endings; this is also facilitated by fatty acids formed as a result of the decomposition and oxidation of fats.
Dandruff is a very disturbing symptom of hair disease and disorder in the body itself, so at the slightest sign of dandruff, do not be too lazy to consult a specialist and immediately begin the fight against this scourge.
