Nowadays, many young people are plagued by hair loss problems. Some knowledge about "hair loss" is also often hotly debated. Recently, topics such as "often pulling hair will become more and more bald" and "men bald for half a month, growing hair without shampoo" have been on the hot search. So, are these claims accurate? How can hair loss be prevented? Today (May 9), the reporter interviewed relevant experts to answer.
If you have white hair, can you pull it out? According to dermatologists at peking university first hospital, pulling out white hair does not curb the production of white hair, but will lead to mild damage to hair follicles. If you pull your hair regularly, it can lead to the permanent disappearance of hair follicles and less and less hair.
Experts from the Dermatology Hospital of the Chinese Academy of Medical Sciences say that it is okay to occasionally pull out one or two hairs, but it is necessary to avoid long-term and frequent hair pulling.
Jiang Yiqun, chief physician of the Pathology Department of the Dermatology Hospital of the Chinese Academy of Medical Sciences, introduced: "Our outpatient clinic will also receive this kind of patient, he has no way to control his hair pulling action, this is a disease called 'trichotillosis', this situation will cause the hair to become thin, it is a disease, this time is in need of treatment." ”
According to the doctor, hair is divided into hair shafts and hair follicles. Frequent perming and hair coloring, excessive cleaning and other behaviors mainly affect the health of the hair shaft, which is manifested as dry hair. So, what behaviors can cause hair loss?
Jiang Yiqun said: "Mood anxiety and other emotions themselves will cause changes in hair follicles in a stressful manner, so that hair advances to the rest period; the other is called androgenic alopecia, the hairline becomes higher, the top becomes bald, more endogenous factors, but also more or less related to people's living habits." ”
Recently, a man in Hangzhou suffered from hair loss, and for half a month, he did not wash his hair with shampoo, and then he found that he had new hair growing on the top of his head. So, does shampoo really cause hair loss?
Jiang Yiqun told reporters: "In a few cases, shampoo contains certain chemical components, such as some desquamation ingredients, which may affect the growth cycle of hair to a certain extent, so that the regressive period or rest period of hair comes early, and there will be temporary hair loss, which does occur in a few cases." But in general, the basic function of shampoo is still clean, and the impact on hair growth is not large. ”
And some shampoos that are nominally "anti-shedding" and "hair growth" are not effective from the perspective of treatment.
Jiang Yiqun introduced: "Hair loss needs more drug treatment, it has a certain concentration requirement for the chemical components that produce action. ”
Experts said that there are two ways to self-test whether hair loss, the first is not to wash the hair for five consecutive days, the sixth day to observe the hair that falls out when washing the hair, about 50 is normal, more than 100 or more than 300, is the clear "telogen period hair loss". The second is to observe the top of the head, compared with the previous hair seam wider, the hairline becomes higher, the hair becomes thinner and softer, etc., may be "androgenic alopecia".
To prevent hair loss, you need to stay up late, sleep well, not over-clean, wash your hair two to three times a week, and the scalp oil can be appropriately increased.
