The most commonly recommended time to wait before washing your hair after a perm is at least 24 to 48 hours, with some experts advising up to 72 hours (3 days) to allow the perm chemicals to fully set and the curls to establish properly. Washing your hair too soon after a perm can loosen or weaken the curls by interfering with the setting process. Here are key points about washing hair after a perm:
- Wait at least 24 hours before washing as a minimum.
- Waiting 48 to 72 hours is often recommended for the best results.
- Avoid brushing or combing the hair aggressively during the first 48 hours after the perm.
- Use gentle, sulfate-free shampoos designed for chemically treated hair when washing.
- Be gentle while washing and drying to protect the curl pattern.
In summary, it is safest to wait at least 48 hours (2 days) before washing your hair after a perm, with some professionals recommending up to 72 hours to ensure the curls set well and last longer.
