Researchers say that several chemicals found in hair straighteners, such as parabens, bisphenol A, metals and formaldehyde, may increase the risk of uterine cancer. "It is estimated that 1.64% of women who have never used hair straightening products before the age of 70 will suffer from uterine cancer; But for people who use it frequently, this risk is as high as 4.05%. " Alexandra White, the lead author of the study and head of the NIEHS Environmental and Cancer Epidemiology Group, said. The research team previously found that the use of permanent hair dyes and straightening agents may also increase the risk of breast cancer and ovarian cancer.
In this study, frequent use of splint straightener is not recommended. Yang, chief physician of dermatology department of Peking University First Hospital, told Global Times Health Client reporter: "The correlation between hair straightener products and the incidence of uterine cancer can be used as a reference. Although it may not cause cancer after use, everyone should pay attention. Because too many chemical products with straight hair are improperly used, it may cause some harm to the body. "
Yang introduced that the main component of straight hair products was ammonia water, which was abandoned because it was too harmful to hair. At present, the chemical products of hair straightening in barbershops are mainly ionic hair straightening dew and hair straightening cream, which soften the hair by chemical action on the hair, and then achieve the purpose of straightness and fullness. The chemical components contained in it will destroy the skin barrier after contact with the skin, making it easier for harmful substances to enter the human body and endanger health.
In addition to using potions, many beauty lovers often use straight clips to straighten their hair in a short time by high-temperature heating, which is also harmful to their hair. The temperature of hair straightener is very high. If used repeatedly, it will increase the brittleness of hair, not only lose luster, but also easily lead to hair breakage.
Reduce the damage to the hair and try not to apply it to the scalp. As a chemical preparation, hair dyeing/hair straightening cream may be harmful to human body only after it is absorbed by the skin, so be careful when using it and try not to apply it to the scalp.
Do a skin test before doing it. Chemical components in hair dye/hair straightening cream may cause skin allergy, so it is best to apply it behind the ear and try it on a small area before use.
Follow the packing instructions. Barber shop staff are relatively professional and skilled, but if they use it by themselves, they should strictly follow the instructions on the package, especially pay attention to all warning statements to avoid problems caused by operational errors.
Control frequency. It is convenient to dye or straighten hair at home, so some beauty lovers often change their hair styles and colors, but frequent operations may make their hair more fragile, easy to break and damage, and become dull and rough. So be sure to control the frequency, and don't use it if you can.
