Final answer:
You should not perm hair that has been colored because the combination of the chemicals and processing used in both treatments can cause significant damage to the hair.
Step-by-step explanation:
The question is related to the treatment of colored hair. When you have recently colored your hair, it is not recommended to perm it, as perming involves additional chemicals and heat that can stress and damage colored hair. Coloring changes the hair's structure through a chemical process that involves permanent hair coloring, which removes the natural color and adds synthetic color. Perms, which can be done through thermal or chemical means, use chemicals to change the shape and texture of the hair. Both processes can be quite harsh on the hair, so combining them can lead to over-processing and potential damage to the hair. Therefore, it is advisable to avoid perming colored hair to maintain its health and vibrancy.
