Nowadays, dyeing hair has become a fashion. Young people can change the color of their hair according to their mood and fully display their personality with clothing and makeup; Middle-aged people have to dye black frequently because they keep growing white hair. High frequency of dyeing hair is definitely harmful to hair and even health. How to reduce the harm of dyeing hair to the body? The reporter asked Lai Wei, head of the cosmetics human safety and efficacy testing agency of the Ministry of Health, and Jin Li, a senior hair stylist in Su Hao, to talk about how to dye hair scientifically.

Jin Li said that 70%-80% of customers in Su Hao dye their hair. Many people will ask when dyeing their hair, will it damage their hair or even cause cancer? In fact, dyeing hair will definitely affect the health of hair, just like applying makeup and nail polish, which is harmful to human health, but now is an era of loving beauty, and healthy hair is not necessarily beautiful without hairstyle. What we have to do is to minimize the damage caused by dyeing hair.

Although there are many reports abroad that hair dyeing can cause cancer, there is an article in the French magazine "60 million consumers" that the properties of many components in hair dyeing have not been fully understood, and some components may be harmful to health and even cause cancer. Research by the American Cancer Society shows that women who use hair dyes may suffer from lymphoma. Levi said that although some chemicals in hair dyes are harmful to human body, especially skin allergies and dermatitis, there is no definite evidence that hair dyes can cause cancer.

Dyeing your hair will definitely damage your hair.

The biggest concern for ordinary people to dye their hair is the damage of hair dye to their hair. KingLee, who has done a lot of bleaching and highlighting on hair, said that because a large amount of alkaline substances enter the hair during dyeing, the original protein and amino acids are destroyed, and the dyed hair will become dry and lose luster and elasticity, so the damage to the hair is inevitable. Now try to use low alkalinity hair dye cream. When dyeing hair, some hair care ingredients are usually added, which is the popular hair care dyeing at present-hair care and hair dyeing are carried out at the same time.

Levi believes that the biggest harm of hair dye to hair is that it contains hydrogen peroxide, which not only oxidizes but also bleaches. Before, white hair was dyed into black hair without bleaching, as long as the color was formed. It is popular to dye black hair in different colors, such as yellow and burgundy, which requires special substances, such as ammonia water, to bleach black hair first and then add artificial pigments.

Skin test is very important when dyeing hair.

Dyeing your hair is like making up. If the skin is sensitive, pay attention to safety when dyeing hair. Generally, it is necessary to do a skin test and apply the hair dye to the back of the neck or ears to observe whether there are allergic reactions such as redness and swelling. It will be safer to dye your hair after this test. When dyeing hair, the hair dye is not directly applied to the scalp, generally 1-2mm away from the scalp. If some basic dyes are directly applied to the scalp, it may lead to an increase in dandruff, because the PH value of the skin is weak and acidic, and alkaline substances will make the skin desquamate.

Lai Wei once met a man who had dyed his hair for a long time. Because of his white hair, he needs to dye it once a month The scalp itches for a few days after each dyeing. Many doctors say it is seborrheic dermatitis, which can't be cured. Later, it was discovered that the scalp itch was caused by dyeing hair.

Hair dye contains complex chemical components, which can cause skin allergy, hair quality change or shedding if used improperly. There are many brands of hair dyes on the market, so you'd better consult a barber before using them.

Make-up dyeing is needed 1-2 months after dyeing.

About two months after dyeing, the hair is oxidized by air, water and sunlight. And the pigment particles are constantly losing, so they will fade, just like new clothes. If you wear it too many times, it will naturally fade. Jin Li believes that makeup dyeing should be carried out at this time. Generally, dyeing hair can last for 6-8 weeks and keep the color basically unchanged, or you can experience 16-20 shampoos. You need to replenish it in time after dyeing your hair. When the new hair grows 2-3 cm, you should go to a professional hair salon to supplement it. Make-up dyeing is not only a process of consolidating hair color, but also a process of caring for hair.
