ok thanks everyone, I'll get it from sally's website. I can't find "curl remover" in any shop, I don't live in the US, I've never seen this product over here in Europe.
Yes Debbie, my units are always too curly for me, I've got very straight hair and even if I wet them,wash them, etc., etc., they're always too curly.
I've been having this same problem ever since I started wearing about 2 years ago, even if I order straight hair, it's never straight enough...
Anyway, I'll try this product and see how it works.
