According to the "China Hair Loss Survey" released by the China Association for Health Promotion and Education at the end of 2011, the number of hair loss people in China is about 200 million, which is not a small number. But generally speaking, under the normal metabolism, the hair is in the growth period, the degeneration period and the rest period respectively. It is normal to drop dozens of hairs every day. But if it lasts for one or two months and more than 100 hairs every day, it is necessary to be vigilant. This is likely to be pathological hair loss, which needs to be checked in the hospital. In addition, the causes of hair loss are no longer the same as before. Environment, emotion, life, heredity, etc. may cause a lot of hair loss. Several main causes of hair loss are as follows:

1. Androgenic alopecia

It is basically determined by genes. In this case, hair follicles are particularly sensitive to androgen, and will become smaller under the influence of androgen. The hair grows thinner and shorter, and may fall off before it grows.

2. Nutritional alopecia

Female compatriots who rely on dieting to lose weight have noticed that excessive dieting will cause digestive and absorption dysfunction, and it is difficult to have sufficient protein, iron, zinc and other nutrients to supply hair follicles. After * * *, it may not have lost much weight, and hair lost a lot.

3. Divine alopecia

Under the effect of long-term mental stress, endocrine balance is disturbed, which will also affect the growth of hair. Alopecia areata is often caused by this factor.

4. Pathological alopecia

Hair loss may be caused by acute infectious diseases, fungal infection of head skin, thyroid dysfunction, and some drug courses (such as chemotherapy); Generally, hair will grow again after physical recovery or drug withdrawal.

5. Postpartum alopecia

During pregnancy, estrogen secretion in the body of pregnant women increases, and estrogen may promote hair growth and extend the "retirement time" of hair. After the baby is born, the estrogen content in the maternal body begins to decrease, and the proportion of sex hormones in the body returns to the normal balance state before pregnancy. Although new hair is sprouting at this time, on the whole, more hair is lost than long hair.
