Disadvantages of perm:
1. Ammonium sulfonium in perm solution enters the cortex through the hair scales on the hair surface, changing the protein chain structure of hair and forming curly hair. In the process of perm, the alkaline components and oxidation in the solution will cause the scales on the hair surface to be destroyed.
2. Leaving the internal structure of hair unprotected will lead to the loss of water and nutrients, which is harmful to hair, scalp and hair follicles, and will denature the keratin of hair more or less, making hair easy to turn yellow, brittle, dull and inelastic.
