When I fell asleep, I found that the pillow was covered with hair, I combed my hair and found that the comb was covered with hair, after taking a shower, I found a pile of hair gathered at the sewer entrance, dried or blow-dried the hair, and there were several hairs on the towel...Although The total number of human hair is more than 100,000, and about 0.1% of the hair will be replaced every day, that is, a normal person may lose about 100 hairs a day, but according to the actual observation of many people, it seems that the hair lost in one day has long been lost. There are more than 100, and I don’t see any improvement just by looking at it. Every time I touch my head, I will find that my fingers are closer to my scalp.
Medically, this kind of hair loss is more than 50-100 within a period of time, and the new hair is not enough to fill the vacancy. It is called "rest period alopecia", also called "severe hair loss." This phenomenon is common in the following people: excessive weight loss, pregnant women, sudden stress (such as sickness, divorce, unemployment, etc.), high fever (especially fever after high fever), recovery after surgery or serious illness, and withdrawal of contraceptives, etc. .
It can be seen that most people experience telogen alopecia when the above major changes occur in the body. Therefore, patients with telogen alopecia generally can grow back to the original level after a period of time. Under a certain state of stress or stimulation, excessive hair loss will always exist, so try to avoid the aforementioned incentives and learn to decompress yourself.
In addition to telogen hair loss, there are some reasons that cause hair to fall off a lot and cannot regenerate. The total amount of hair continues to decrease. This situation does not stop automatically. Medical students call it "growth-period hair loss." Hair loss during the growth period may eventually cause the patient's hair to fall out completely and cannot grow back. This phenomenon often comes from the following reasons: genetic factors, overreaction of the immune system, certain drugs and therapies, harmful hair care products, and excessive pulling of the hair.
However, hair loss during the growth period is often caused by obvious incentives, so the hair will generally regenerate after the specific incentives are removed. It should be noted that if you suspect that a certain medicine or therapy is the cause of hair loss, please inform your doctor in time, but do not stop the treatment yourself. If hair loss during the growth period is caused by other reasons, it may need to be treated as soon as possible. The earlier the treatment, the better the effect. The hereditary hair loss can also be treated to improve the symptoms. If it is not treated in time, it will only become more and more serious.
For many women who love a variety of hairdressing methods, and at the same time desire a beautiful hair, some of their "hairdressing" behaviors may increase the possibility of "growth-period hair loss".
For example, braided hair is a kind of traction alopecia, which refers to hair loss caused by external force, including ponytail, fine braid, curling, combing, panning, using too tight hairpins, etc. Cause traction alopecia.
For example, to straighten the hair, there are two ways to straighten the hair, one is the hot straightening method, and the other is the chemical straightening method. The perm straightening method uses high heat to shape and straighten the hair, but the effect is easy to rebound and requires repeated perming; the chemical straightening method uses some special ingredients to reshape the hair so that it can be straightened from curls and has a long-lasting effect . Regardless of the method, although it has little effect on the hair follicles and will not cause hair loss, it will make the hair fragile and easy to break. The broken hair is difficult to grow back for a while, so the overall hair appears to be less. .
Another example is using the wrong hair dryer, the wind is too strong, the moisture is lost too quickly, and it hurts the hair; the temperature is too high, the hair is too close, the hair is dry and hot, and it hurts the hair. Therefore, when using a hair dryer, you must do three things: a lower gear, a lower temperature, and a distance away from your hair.
In addition, wearing a hat can also cause traction alopecia, especially when some people have larger heads and they like to wear hats that press the scalp tightly, so that long-term squeezing of the hair roots is also a kind of pulling, and some people I like to tie my hair into a ponytail, and then put on a hat to press the hair on my forehead back. This is a "double pull". Wearing a wig that is too tight is similar.Back
