My 10 year old daughter has long curly kinky hair that she can't stand. I can empathize as she inherited my hair. But on her it looks cute! But when I saw this infomercial, I thought I should give it (model # SS9) a try, even though styling hair is not my thing. I can honestly say that it is as easy as it shows on TV and does a really nice job. My 15 year old who has beautiful thick wavy hair also uses it, and she says its way better than any straightener she's ever owned and she's owned plenty. The straight hair lasts until it's washed. This is a great product.
