Yes, you can wash your hair on Sunday.
When you first get a perm, wait 48 before you wash your hair. After that, you can wash it every day or as needed. I wash mine every day because my hair is very fine. It all depends on your hair type.
Wait about 3-4 full days, Because even though the chemicals are washed out and the hair is now permanently straight, Its still takes a bit for the hair to get used to its new texture

You have to wait about until your color is mostly out. Dieing your hair after it just got died can cause hair loss. I would just wait until it's all out. If you want to get your color out quickly take care of your hair. Take regularly showers, to wash out hair colors, and brush hair very often.
You must wait 24 hours before washing your hair.
