I had (still hope to have once it recovers from pregnancy lol) thick hair with a curl. I found as a kid the cheap ones did nothing but frizz my hair more.
I have ghd...way to expensive but I plan on getting cloud9 ones next. Australian made and are WAY better.

For my first ones I went into price attack and spoke to the girls there and the recommended a good pair for my hair type. Might be worth a shot. Just don't want to damage your dd's hair . Remington sound like a good deal though too
