WASH IT! You aren't supposed to wash your hair right after a perm so maybe you will catch it in time (thank you Legally Blonde 2). If not, it will settle just give it time. In the mean time get some heat spray to protect your hair from damage and blow dry your hair straight.
The worst thing you can do is wash your hair 48 hours after a perm, that is what my friend's husband who is a hair dresser said. If you wash the next day you mess things up really bad. Another problem I see is that there are not a lot of people getting perms in the shops and I think hair dressers are not experts in them. There are so many out there. I really hope you don't get that puff cotton hair look, because I had that about 10 years ago from a bad perm and had to get all my hair cut off. Maybe go to a good beauty supply store and see what products they recommend. Good luck, I am dealing with my own hair problem now. (bad cut).
i go to hair school and deal with perms all day! mostly with little elderly ladies....if the perm is too tight or too frizzy using a medium size curling iron after your hair has dried with make you have bigger looser curls, also a heat protectant will eliminate alot of that frizz and keep your hair from curling back up! also if you have time try velcro roller when you hair is wet!
