What kind of shampoo makes an 11 year old have straight hair?

My 11 year old daughter has really curly hair, and she said she wants it really straight. She always uses straightening iron, but I heard it damages your hair. What kind of shampoo and conditioner makes a kid's hair go straight?What kind of shampoo makes an 11 year old have straight hair?
impossible unless you use harsh chemicals( i doubt you want to) And no shampoo and conditioner is going to do that! Tell your daughter to except her curly hair! :DWhat kind of shampoo makes an 11 year old have straight hair?
ive used ';straighten up'; by sunsilk shampoo and conditioner. its purple. then there is a cream that is the same brand/line and you put it in ur hair when its damp then blow dry straight with a really big round brush. maybe run a straightener over it a little on low heat if its still a big poofy. straighteners dont do ur hair any good but as long as you trim it often and don't do it every day its the same or less damaging than a curling iron.
i like the Bed Head products cause they work really well and they have a straight hair one but they are pretty expensive
