Basically it is perm solution. I have seen it sold as kits in drugstores and should straighten your wavy hair without a lot of damage. I think it is made by Olgilve(sp). It is NOT the straightener used on African American super curly hair, so be sure you do not get that type of straightener.
I actually use a straightener on my already straight hair to get it super straight with no heat. I feel that a chemical treatment once is a lot better for my hair than the constant application of heat.
Hope that helps!
