Which is more harmful, dyeing hair or perming hair

The hairdressing industry has become more and more popular now. Many people like to style their hair. At the end of last year, tinfoil perm was very popular. Most people will find that the color of their hair will turn yellow after perming, which will affect the overall complexion. So they will dye their hair after perming. So which one is more harmful, perming or dyeing?

1. Regarding perming, some perming agents sold on the market contain thioglycolic acid substances, which have the risk of allergic and carcinogenicity. Consumers should use them with caution. The principle of perming: the ammonium sulfonic acid in the perm solution enters the cortex through the hair scales on the surface of the hair, changes the protein chain structure of the hair to form curls, and then the fixative is applied to fix the hairstyle. During the perm process, the alkaline components and oxidation in the solution will damage the scales on the surface of the hair, causing the loss of internal moisture and nutrients, which is harmful to the hair, scalp and hair follicles, making the hair prone to yellowing, brittle, dull and inelastic.

2. Hair dyeing. Most ordinary chemical hair dyes contain toxic chemicals such as paraphenylenediamine and heavy metals. Many people have allergic reactions to hair dyeing, such as rashes, dizziness, and even redness and swelling of the skin. Therefore, choosing healthy and safe plant hair dyes is the best choice. Dr. Tao's plant-based hair dye does not contain any harmful chemicals. The coloring principle is to use the natural tannins, tannins and natural green alum in hematoxylin extract, gallnut extract, and witch hazel extract to combine into stable black macromolecular couples for dyeing, which is healthy and safe.

3. Perming and dyeing hair can cause cancer because pigments will penetrate deep into the body through hair and hair follicles. These pigments contain a large amount of inorganic substances and some heavy metals. Once these elements enter the human body, they will react chemically with the chemicals in the body. Under the action of the kidneys and liver, some are excreted, while some remain in the body and circulate. In particular, heavy metals cannot be absorbed by the human body and will eventually remain in the body. If they are mixed into blood cells and become the cell nuclei, the blood will undergo great changes. If they remain in the liver, the liver will become its appendage, and its stem function will be weakened, leading to an imbalance in the body and causing cancer.

4. Once the pigments from hair perming and dyeing flow into the body, they will inevitably meet the liver. The liver is a detoxifying body, but it cannot detoxify heavy metal toxins. If the liver is in a detoxification state for a long time, its liver function will inevitably weaken.

5. The kidneys also have the function of detoxification. Once the pigments meet the kidneys, they will be eliminated. However, the pigments are not so easy to be eliminated. If the kidneys are in conflict with pigments, heavy metals and other substances for a long time, it will inevitably cause nephritis, kidney disease, renal failure, etc.
