A perm is a chemical treatment that permanently changes the shape of the hair. After getting a perm, it is important to wait 24 hours before washing the hair. This allows the chemicals to set and the hair to adjust to its new shape. Washing the hair too soon can cause the perm to fail.
Waiting 24 hours after a perm has many benefits. It allows the chemicals to fully penetrate the hair shaft, resulting in a longer-lasting perm. It also gives the hair time to adjust to its new shape, reducing the risk of breakage. Additionally, waiting 24 hours helps to minimize scalp irritation and dryness that can be caused by the perm chemicals.
