I got a perm today (finished around 1:30pm). While I was still at the salon my stylish noticed that some of the ends of my hair (the bottom portion) were a bit straight. She told me we might have to perm them again that it might not have taken the perm completely. She did tell me to wait until I could wash my hair (2 days from now) until we made that decision. Is this normal? When I wash my hair will it stay the same or will it all be wavy like the rest of my hair?
