Chemical put in your hair to make it dry into waves?


i was wondering what it was. i know its not a perm. i read in a magazine that stars like nicole richie get it done and it makes your hair air dry into waves. i was wondering what its called, how much it costs, and how long it lasts. thanks so much :)What chemical is put into celebrities hair to make it dry into waves?
Maybe it's just a wig, you don't know it.What chemical is put into celebrities hair to make it dry into waves?
You can buy wigs/weaves with waves. you can twist or braid your hair at night while damp then take it down in the morning, or you can buy a deep waver. Revlon makes them.
