* Hair is still fragile: A perm uses chemicals to alter your hair's structure. The cuticle, the outer layer of your hair, is still open and vulnerable for a few weeks after the perm. Dyeing can further irritate the hair, potentially leading to damage, breakage, or uneven color.
* Chemical interactions: The chemicals in the perm solution can interact with the dye, leading to unpredictable color results. This can result in uneven color, unwanted tones, or even color fading faster.
It's best to wait at least 2 weeks after a perm before dyeing your hair. This allows your hair to fully recover and become more resilient.
If you're unsure, consult with your stylist. They can advise you on the best course of action for your hair type and condition.
