Question: can you dye your hair before a perm?
Answer: Perm first to ensure that the perming process will not interfere with your newly applied color. ... Some Semi-Permanent (lasts though 8-12 shampoos) and Demi-Permanent hair color (lasts through 28 shampoos) can be used the same day as your perm—as long as your scalp is not irritated and is in good condition.
