Is there a difference between good and bad perm solutions?

In order to make their hair more beautiful, women often go to the barber shop to perm or dye their hair, etc. However, since the types and prices of perm solutions are different, hairdressers in barber shops will ask women whether to use good quality or average quality perm solutions. This question has caused a lot of women to wonder, so is there a difference between good and bad perm solutions?

Second, no matter whether the perm solution is expensive or cheap, as long as it is used on the hair, it will cause damage to the hair. The ethyl mercaptan acid contained in it is highly toxic and can damage the hair. In addition, perming itself can cause irreversible high-temperature damage to the hair. The biggest difference between expensive and cheap perming solutions is probably that the more expensive solutions have a slightly softer and slower effect on the hair, resulting in better perming results and lasting longer. Cheaper solutions cause more direct damage to hair and the perming effect lasts slightly shorter.

2. Look at the softening time. If the perm solution is of good quality, the softening time will not exceed 1 hour, usually 30 to 40 minutes.

3. Scalp irritation. Perm solutions of better quality will cause less irritation to the scalp. If there is obvious stinging or other discomfort, the solution is of very poor quality.
