This is a great product from a great line. i have to say i worship the kpak line, but this product in paticuler. i swear by this product! If you have dry hair, split ends, or use heat products that cause breakage u need this!! it seals the cuticule and helps to mend the ends. my hair had gotten really bad at one point, there was so much breakage it was breaking up the cuticule- this product saved my hair! It is a little pricey but if u love your long hair and hate having to get more then u want cut off due to split ends its worth it!!
