Thanks for sharing your useful infos keratin4u!

Well I still doubt if it does what it says. And I don't understand why to flat iron at such a high temp. (230 C). Product is rinsed out, so you flat iron directly the hair with no treatment protection ! Seems horrifying...What's the point?
And why anyway you have to rinse out the product and not flat iron it on hair?

I think I ll go for kerpremium too
