Human head hair follicles have their own life cycle, it can be said that the cells have been in the metabolism, the hair follicles have been in the replacement, so in fact, everyone will have hair loss, and can not be stopped every moment, just everyone's hair renewal rate is different. Because of this, it is still normal to keep the hair that falls out only inside a limit, generally the number of hairs that fall out of a normal person every day is around 50 - 100, more than this number there is a hair crisis.

The total amount of hair loss of a normal person a day is not counted, or no time and energy to count, so there are two tricks to judge the hair loss, the first is to pull, gently combing back from the root of the hair with your hand and repeat two or three times, if two or three hairs fall out every time, it is likely to be a pathologic hair loss. The second trick is being checked that is to go to the hospital or find a professional inspection organization to check the state of the hair and hair follicles to eliminate the lesions.

This is an important step in determining whether your hair loss is real or normal. Many people get caught up in fantasizing about baldness and causing anxiety due to observing a large amount of hair, which is not advisable.

As mentioned earlier, hair loss is within the normal range and can be regenerated, the name is physiological hair loss, while it is often referred to as pathologic hair loss, which can be broadly categorized as seborrheic alopecia, hereditary alopecia, alopecia due to malnutrition, and alopecia due to mental stress, and whether or not alopecia is treated depends on the specific cause of hair loss.

Seborrheic alopecia, also known as androgenetic alopecia, is mainly concentrated in men and often acts in conjunction with hereditary alopecia, resulting in shiny head, oily skin, facial acne and hirsutism. Hereditary hair loss is determined by genetic factors. Both men and women can be affected by hereditary hair loss, but men are more susceptible to androgenetic alopecia than women. Hereditary alopecia in women usually results in thinning hair, while men tend to go bald.

Malnutritional deficiencies lead to hair loss, for example. Zinc deficiency, protein, vitamin D, vitamin B, anemia, vitamin A overdose, good water quality, thin and weak, and other key factors can lead to hair loss phenomenon, the specific causes of hair loss lack of each substance of the hair loss principle is different, such as protein, lack of protein. The body may inhibit the protein ration of the hair, which leads to hair loss; and vitamin D can play a role in the growth of new hair follicles, the lack of vitamin D is the same as the inhibition of the growth of new hair; the water quality is often alkaline, while the hair growth environment is acidic and so on. Mental stress causes hair loss. This is a condition in which the patient experiences major life changes and life stresses that result in massive hair loss in a short period of time. The advantage is that this symptom is temporary. In addition to hereditary hair loss, other causes of hair loss can actually be reversed as long as the hair follicles are not permanently damaged.
