How long should a client wait to wash their hair after getting a perm?

After getting a perm, it is advisable for clients to wait at least 48 hours before washing their hair. This waiting period is crucial because the hair needs time to fully accommodate the new shape and texture created by the perming process. The chemicals used in perming work by breaking down the disulfide bonds in the hair and then reforming them into new curls or waves. Washing the hair too soon can disrupt this process, potentially leading to looser curls or even straightening of the hair.

By allowing a full 48 hours, the hair has a better chance to stabilize, and the perm can hold effectively, ensuring the desired results last longer. This timeframe also helps to minimize any potential frizz or damage that might occur if the hair is manipulated or exposed to water and heat too soon after the chemical application.
