What is the recommended waiting period before washing hair post-perm?

The recommended waiting period before washing hair after a perm is 48 hours. This duration is crucial because it allows the hair's new chemical bonds, created during the perming process, to fully set. Washing the hair too soon can disrupt this setting process, potentially leading to diminished curl definition and overall effectiveness of the perm.

During the first 48 hours, the hair is in a fragile state, and any manipulation, including washing, could result in unwanted frizz and a loss of curl. It is also advisable to avoid other chemical treatments and heavy styling products during this period to ensure the longevity and integrity of the perm. This guidance is based on standard practices in hair care following a perm to achieve the best results.
