As we all know, a perm will definitely hurt your hair, and it must be dry. I think readers must have permed a lot, and their hair is not particularly dry, and there is nothing wrong with it. This is the best perm effect. Proper operation will reduce the damage of perm to hair, which is completely possible.
As long as it is a perm, it will affect the hair quality more or less. The concept of health is to control the softening degree, the temperature during heating and the action time of the second agent more accurately through technical means, so that the perm water and hair can function normally, and not too much, so that the curl of perm can be considered healthy. The measure of this standard is not to use any care styling products after perming, to dry the water with a towel, and to dry the hair with cold air. Hair has good luster, good curl elasticity and good cohesion, which is considered as a healthy perm.
There is another saying about healthy perm, that is, how is the hair quality before perm? After perming, the hair quality does not change much, but it is curly. The method mentioned in the day to test whether it is healthy does not use any styling products, and the hair is dried with cold air, which has elasticity and good gloss, and can also be regarded as a haircut and perm.
After perming, the hair is short-tempered and dry, and the curly hair is inelastic in the wet state. In the dry state, the curly hair becomes bigger and cannot be formed, indicating that the hair is too hot. This is due to the operator's technical level, or incorrect operation process, and insufficient product control ability.
Precautions:
Hair has beautification function, but it doesn't attract people's attention as often as skin. On the contrary, the health of hair is often neglected. In fact, human hair is very delicate. Only by fully understanding the characteristics of hair can we carry out the correct operation and keep the hair in a normal state without losing its luster.
The direct relationship between perm and hair is to soften hair scales and let drugs enter the second layer of hair: cortex, thus changing the molecular structure of cortex. Let's look at the relationship between cortex and our hairdressing. The cortex is composed of salt bond, hydrogen bond, disulfide bond and amino bond.
