Thanks for posting the info on this type of keratin treatment. I have not heard of this particular keratin product before, but I have read similiar methods of that process (for the wash and wear type keratin). I did not realize you needed to wait four days to wash it again though - that seems to defeat the purpose of the wash and wear?? Please post some after pictures - would love to see them.
