Can you reuse a used perm?

Reusing a perm on hair that has already been permed is generally not recommended, as it can lead to damage and overly processed hair. The chemicals used in perming can weaken the hair structure, making it more prone to breakage. It's best to wait until the hair has grown out or is in a healthier condition before attempting another perm. Always consult with a professional stylist for personalized advice.
