The principle of perm

It is the ammonium iron acid (alkaline) in the special perm solution that enters the cortex through the hair scales on the surface of the hair, changing the protein chain structure of the hair to form curls. Perming usually starts with using reducing chemical solutions to break up the small springs of cysteine, breaking the sulphur-sulfur bridge bond of cysteine ​​and becoming 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.

In the process of perming

The alkaline ingredients and oxidation in the potion will damage the scales on the surface of the hair. 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, and should not exceed four times a year.

The dangers of hair perm

Chemical substances are the most worrying among them. The hidden and serious harm of perming is the chronic damage to the human body which may lead to various cancers after many years. The scalp has the most densely packed hair follicles in the human body. Chemical toxins can be absorbed into the body through the scalp hair follicles. With long-term use, chemical toxins accumulate in the body and enter the human blood. If the dye concentration is too high or dyeing and perming are too frequent, it will damage blood cells. It may cause leukemia or lymphoma, and may also cause intractable diseases such as bladder cancer, breast cancer, and aplastic anemia.
