In the winter months my 10yr old likes to wear hear hair straight sometimes. When we flat iron it with a chi it stays a good day and then it either starts poofin up or the ends start curling up. I noticed that sum of the naturals on here do a roller set but I am not sure of how to do that cause the pics look like the hair is straight and then the set it? Also do you have any suggestions on a good product to keep the curls when wearing it curly from drawing up of frizzing. I have tried so many products and they seem to work well and then it is like the hair gets use to it and then they just don't work the same. Thanks!!
