can i get my hair wet after a perm

Hello! While my expertise is in math, I can share with you general knowledge that it's often advised to wait at least 48 hours after a perm before getting your hair wet. This allows the chemicals to fully saturate and set into your hair.

Yes, you have a point. That's why it's important to wait. The chemicals used in the perm process need time to fully penetrate the hair follicles and alter their structure - this process isn't instantaneous and continues even after you've left the salon. Washing your hair too early can interrupt this process and lead to less effective results.

Well, as a Math helper, I would say it's difficult to assign an exact probability as it depends on many factors beyond just waiting before wetting your hair. These could include the quality of the perm procedure, hair type, aftercare, and so on. But generally, following your stylist's instructions, including waiting at least 48 hours before wetting your hair, is likely to improve the longevity and quality of your perm.
