Why shouldn’t I wash my hair for 48 hours?

During the treatment, we have taken your hairs’ pH level to a low level and then neutralised it, bringing the pH level back. After, we just want to let your hair rest. You can get it wet, you can style it and do everything you would normally do. We only ask that you do not shampoo for 48 hours as this could once again alter the pH level, which we want to avoid for two days following your nice and smooth treatment.
