Little S posted a video and admitted that she no longer dyes her hair. This is because hair dyeing has a certain impact on the human body. With the development of the times, people's aesthetic concepts are gradually changing. Both men and women have never stopped paying attention to hairstyles and hair colors. Especially for women's needs for hair color, from dark and thick to discolored, appropriate hair color can not only bring people different sensory experiences, but also enhance their spiritual temperament.

Many people have seen artists change their hair color from time to time. Young idol artists, especially, usually dye their hair in light colors such as blue, pink, and blonde. The quality of the hair is also very smooth when they look on camera. Many people mistakenly believe that frequent hair coloring only requires proper care to ensure that the hair does not dry out and turn yellow. But in fact, the hair texture of celebrities is no different from that of ordinary people. It just doesn't look damaged on stage or on a nice screen. If you dye your hair a light color, you need to fade it before dyeing so that the color after dyeing will be brighter and the effect will be more obvious. But at the same time, if you bleach and dye your hair many times, although your hair color will be beautiful, the quality of your hair will be greatly damaged, which can easily cause dry hair, hair loss and other problems.

Ammonia, the catalyst used in bleaching, is an alkaline substance that corrodes and irritates skin on contact. It can absorb moisture in skin tissues, denature tissue proteins, saponify tissue fats, destroy cell membrane structures, and cause skin pigmentation or finger ulcers after long-term exposure. ?Ammonia not only comes into contact with the skin, but can also enter the human body through the scalp hair follicles, thereby irritating and corroding the human upper respiratory tract and weakening the human body's resistance to disease. When the concentration is too high, it can also cause cardiac arrest and respiratory arrest through the reflection of trigeminal nerve endings, which is very harmful to the human body. Don’t be superstitious about pure plant hair dyes. Pure natural hair dyes do not exist. So we should try to avoid dyeing our hair. Don't actively dye your hair to protect your hair and body health.
