The difference between protein perm and ordinary perm

The difference between protein perm and ordinary perm lies in the degree of damage to the hair. Protein amino acid perming products can effectively deal with moderately damaged hair or fine hair, and can effectively inhibit the damage to hair scales and ensure the minimum damage to hair. However, ordinary perm has no protective measures, which is very harmful to hair. Perm is a kind of hairdressing method, which can be divided into physical perm and chemical perm. Perm can enrich hair (with curling effect) and change the shape and direction of hair (with little curling effect). The basic process of perm is divided into two steps. The first step is to break the sulfur bond and hydrogen bond in hair through chemical reaction, and the second step is to recombine and stabilize the hair core structure.
