Rip off

Did not even touch the dryness of my hair- in in fact, not using conditioner and using this instead made my hair a frizzy mess.

Lives up to the hype

One of those products that, despite being expensive, is worth every penny. I was reluctant at first to wash without using conditioner but K18 makes the hair so silky, you don't even notice you haven't used conditioner.
