Hair loss is a physiological or pathological process. Pathological hair loss leads to their even thinning, partial or complete absence in limited areas or total baldness. Causes of hair loss are lack of vitamins and trace elements, side effects of drugs, hormonal and infectious diseases, stress, heredity, improper hair care. Often, the elimination of these causes leads to the restoration of hair.

Hair loss
Hair loss is a natural process. Every day a person loses sixty to one hundred hair. Normally, the number of newly grown and lost hair is at the same level, but under certain conditions the number of lost hair increases. If hair loss takes on a total character, then it can lead to baldness.

The average lifespan of a hair is about seven years, then it moves into a phase of active growth that lasts from 2 to 7 years. After that comes the catagen phase, that is, the phase of preparation for a fall of 2-4 weeks. And, finally, the hair loss phase is 3-4 months, depending on the depth of the follicle. Therefore, if there is a loss of hair that exceeds the natural loss, then the cause should be sought three months earlier.

Causes and clinical manifestations of hair loss
The causes of baldness and hair loss are different, although as a result of both conditions a person loses a significant amount of hair. One of the common causes of hair loss is a lack of iron in the body. Intense physical exertion, unbalanced diet, and tight diets can also lead to the development of anemia. In this case, the hair becomes dull, dry and brittle, in the absence of therapy, the process of hair loss only increases.

Stressful situations and disorders of the autonomic nervous system lead to a narrowing of blood vessels on the scalp. With incessant stress, the vessels no longer return to normal, which causes hair loss, as the nutrition of the hair follicle worsens.

Chronic diseases of the body, especially those that occur with endocrine disorders, are often accompanied by hair loss. Diseases of the thyroid gland, polycystic ovary, pneumonia, and syphilis can cause hair loss.

Taking certain medications causes a side effect in the form of hair loss. There are about a hundred drugs with such side effects; they are mainly oral contraceptives, antidepressants, antihypertensives, and steroid drugs.

Means for the correction of the figure, which contain salts of heavy metals and selenium, do not favor the good condition of the hair, and given that the main effect in the application is achieved due to a laxative result, the absorption of vitamins and trace elements is impaired.

Hair coloring, blow-drying can cause hair loss. Frequent wearing of wigs, hairpieces, overhead strands, as well as products for hair and scalp care, if used improperly, lead to various problems with hair.

Neglect of headgear in the cold season and the abuse of caffeine-containing beverages lead to a constant spasm of scalp blood vessels, which can cause loss of part of the hair.

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 between alopecia and simple hair loss is that in the latter case, the pathology of the hair follicle is not observed.

Therefore, the process of hair loss is always reversible, regardless of the stage. On closer examination, a dark pouch can be seen at the tip of the hair - this is an unfavorable sign. If more than five hairs remain in the hands when the hair is strained, this indicates that hair loss is much higher than normal.

To determine the cause of hair loss is necessary consultation trichologist. Conduct a comprehensive survey, which includes a blood test, the study of hormonal levels, spectral analysis of hair and examinations in order to avoid alopecia.

Hair Loss Correction
For the period of treatment, any aggressive procedures are canceled, such as coloring, perming, and blow-drying.

After the hair loss process is complete, the follicles need some time to recover so that the hair begins to grow again. At the stage of hair loss, the correction is aimed at eliminating the root cause, after which various types of hair growth stimulation are used.

Effective methods for correcting hair loss include massage of the scalp, treatment with medications and hardware treatment procedures. Their effect is based on stimulating hair growth and reducing their loss.

With the normalization of the work of the internal organs and proper care of the scalp and hair, their loss stops. Most often, newly grown hair becomes stronger and stronger than those that fell out.
