Long long ago, many people wore wigs because they got the alopecia. Wearing wigs was beneficial to treat the alopecia.
So what is alopecia? It refers to hair loss. In the regression and resting stage, the hair usually sheds naturally. Because hair in the regression stage is in dynamic equilibrium with the new growing hair , hair can keep its original looking. The above is normally physiologic alopecia. Pathological alopecia refers to abnormal or excessive hair loss. While there are many reasons causing the hair to shed excessively.
The main symptom of alopecia is greasy hair like being applied oil, or dry and fluffy hair without luster, or itching scales caused by light yellow or gray scales attached on the hair. If the male is suffering from alopecia, they mainly get their hair on the front and top of their heads sparse, yellow and excessively soft . Finally their foreheads become bare or just have some fuzz. And the female usually gets sparse hair on the top of their heads without hair shedding flakily.
Many people think that alopecia is caused by the sick hair root . thus many alopecia-proof drugs are directly used on the head. Actually this kind of practice is wrong. We have to know the correct causes of alopecia.
The main Causes : alopecia appears on surface but the main cause lies inside, that is to say disease in appearance. Heat toxin within blood cannot be expelled , which makes the body appear some symptoms.
Those symptoms expressed on head is follicles withering and hair shedding, easy to be broken, oily and nonelastic. The worse situation is hair largely or completely shedding. Specific causes of alopecia can be divided into the following categories:
1, neurological alopecia: under the overwhelming mental stress, blood heat toxin would be accumulated which often increase the shedding hairs. Under the stress, arrector pili muscle contract and hair erects. Vegetative nerve or nervus centralis disorders and the follicle together with dermal papilla is largely changed to be malnourished which result in hair growth restrained. Thus the hair goes into the resting period and the alopecia appears.
2, endocrine alopecia: hair growth is influenced by blood heat toxin which cause the human body suffering from disordered endocrine. So the endocrine disorder often causes the alopecia. The most common is the alopecia caused by psoriasis, mould and disordered androgen.
3、alopecia leaded by malnutrition: the hair is the external performance of physical condition. Obstruction of Blood heat toxin,malnutrition and metabolic abnormality can cause the hair and its color changed. And the severe malnutrition might cause the hair diffusely shedding.
4、physical alopecia: the common physical factors that causes the alopecia include mechanical stimulus or radioactive substances which cause the blood unable to expel heat toxin.
5、chemical alopecia: chemical factors can lead the hair color changed or even the alopecia.
6,infectious alopecia: blood heat toxin accumulation causing sorts of pathogen infection is the main factor of hair diseases. The infections mainly include bacteria, viruses, fungi, helicoid, parasitic infections etc.
7, symptomatic alopecia: some systemic or localized disease also can cause the alopecia.
8, congenital alopecia: completely absent or sparse hair caused by developmental defect. The patients commonly have sparse and fine hairs ,or get the hair shedding or not growing any more soon after they are born. It can be divided into isolated flaw and other anomalies.
9, immunity alopecia: certain autoimmune or immunodeficiency diseases can cause the alopecia. There are also some local autoimmune diseases without involving the main body and other organizations having this power ,too.
10, seasonal alopecia: generally speaking, in hot summer, hair is easy to shed for the high temperature expanding pores. While in autumn and winter,the pores are closed because of the lower temperature, so hair is not easy to shed.
11, the alopecia in the angle of Chinese medicine:weak kidney causes blood dificiency. Because the hair is supported the nutrition by blood. So the mian method to cure the alopecia is increasing and nourishing blood.
12, alopecia caused by masturbation: excessive masturbation can also lead the alopecia. Masturbation has something to do with the alopecia for it can bring excessive androgens. The androgens are closely related with the hair growth and regulation.
13,alopecia caused by excessive weight loss: a lot of women are doing something to lose weight. Because the main element of hair is a kind of protein called fish protein,including copper, iron, zinc and other microelements. While if those nutritions are not enough absorbed due to excessively lose weight, the hair would be malnourished and shed. So everybody should treat the alopecia in time whenever it appears.
