I HATE Frizz-ease. I personally think it's crap. I never works on my hair, except make it greasy.
To make my hair straight I use Tony&Guy. The thing is I don't know if you can get it in North America. I haven't seen it here in Canada, but it might be possible to find it in the US. My mother bought it in England and I think it's fantastic!!!! Either that or Aveda products. I find them great for my hair (and they smal nice too!), but I don't buy them often because they're expensive and I'm a poor student

.
Sometimes I use Citrishine, and that works alright, but Tony & Guy, it's great if you can find it.
edit to correct: whoops, my bad. Tony & Guy products are available in the US. I don't know about Canada though (why are so slow?) The product is No-Kinks Smoothing Balm...fantastic!!!
