Steps. 1  1. Wait at least 3 days to wash newly permed hair, or your perm would not last as long. 2  2. Use hair care products that are safe for permed hair 3  . 3.

Can you dye your hair 12 days after your perm? Correct time between chemicals is (2 weeks) so I am sure that if your hair is in great condition it shouldn't be a problem. Helpful hint: Always perm 1st, the neutralizer whicâ¦h is the second part of a perm has a little amount of peroxide and can cause the hair to lighten. So, due to this I recommend you to perm 1st.
