Which is more harmful, dyeing hair or perming hair?

I believe that hair dyeing and perming are what young people are pursuing nowadays. Young people will choose different hair dyeing or perming according to their clothes and makeup, so perming and hair dyeing are very popular nowadays. We all know that changing the hairstyle or the color of the hairstyle can bring us beauty, but do you know that these hair dyeing or perming are very harmful to our hair, and perming is more harmful than hair dyeing, so let us explain it to you below!

1. The ammonium sulfonic acid (alkaline) in the special perm solution enters the cortex through the hair scales on the surface of the hair, changing the protein chain structure of the hair to form curls.

2. Perming hair usually starts with using reducing chemicals to break up the small springs of cysteine, breaking the sulfhydryl bridge of cysteine ​​and forming two cysteines. At this time, the amino acid chain links of the hair loosen and can be manipulated by people, curling into a certain waveform. Then apply fixative to make the cysteines that break the small springs combine in pairs nearby to form new springs and fix the hairstyle. During the perming process, the alkaline components and oxidation in the solution will damage the scales on the surface of the hair.

3. Leaving the internal structure of the hair unprotected will cause the loss of internal moisture and nutrients, which is harmful to the hair, scalp and hair follicles. It will more or less denature the hair's keratin, making the hair prone to yellowing, brittle, dull and inelastic. Experts believe that perming should not be done too frequently, no more than four times a year; perming should not be done for pregnant women as it will affect the health of the fetus; little girls have delicate scalps, and perming can easily break their scalps and cause bacterial infections; people with dry scalp should not perm their hair often.

4. Therefore, perming should be done according to one’s actual situation.

5. Hair dyeing is to use the alkaline ingredients in the dye to open the hair scales on the surface of the hair (the scales on the hair open when they encounter alkali), and the artificial pigment enters the cortex of the hair and combines with part of the natural pigment to form the desired color. When dyeing hair, ammonia in the dye has a strong destructive effect on the hair scales on the surface of the hair. If not properly maintained, it will cause the hair scales to fall off, moisture loss, roughness and brittleness, lack of luster and inelasticity.

6. Many people are troubled by the fact that dyed hair lacks luster or the color is difficult to maintain. Experts warn that no matter what kind of hair dye or its products are used, dyed hair generally contains toxic aromatic chemicals. Long-term use may damage the body's hematopoietic system or cause fetal malformations in pregnant women. In mild cases, it can also cause dermatitis, skin redness, swelling, itching, ulcers, etc. For the sake of health, try to dye your hair less or not at all. Natural beauty is the real beauty. Many people have allergic reactions to chemical solutions used for hair dyeing and perming, such as rashes, dizziness, and even redness and swelling of the skin. Therefore, special attention should be paid to prevent this allergic phenomenon. You can try a little bit on the skin first. If redness, swelling or allergy occurs, do not perm or dye it.

In the above article, we mainly introduced that perming is more harmful than dyeing, because dyeing hair will damage the hair scales and is harmful to the hair, scalp and hair follicles. It will more or less deform the hair keratin, making the hair prone to yellowing, brittle, dull, inelastic, etc. However, dyeing hair will also cause the hair to lose moisture, become rough and brittle, etc., so it is recommended that you try not to dye or perm hair.
