What are the hazards of perm?

Perm will denature hair keratin and make hair yellow, brittle, dull and inelastic.

One of the most harmful perms is the main potion. Many perms on the market contain alkaline components, which have a certain oxidation effect. Once it touches the scalp, it is very easy to destroy the small skin in the hair, leading to the loss of water in the hair and serious hair loss.

In the process of perming, the alkaline components and oxidation in the liquid medicine will destroy the scales on the hair surface. If the internal structure of hair is not protected, it will cause the loss of water and nutrients inside, which is harmful to hair, scalp and hair follicles.

Extended data:

Generally, perm water is composed of reducing agent and oxidizing agent. The main components of reducing agent are thioglycolic acid and its salts, as well as alkali such as ammonia water, surfactant, stabilizer and so on. Using strong alkaline perming agent to destroy hair tissue and change the links of hair quality can rebuild new structure and shape.

Excessive perm can lead to loose, porous and inelastic hair structure. The oxidant is mainly hydrogen peroxide or sodium bromate to fix the curl. However, excessive use will cause hair to be dry, split, broken and faded.
