Must have
After using this product for a couple weeks it kept my hair healthy and shiny and even made it easier to maintain

Sticky and smells bad w heat
Wish I’d waited for the mini to come out to try this, but I got a full size because I was so excited to “upgrade” to K18. I hate it. It tangles my hair. It smells bad when heated, which is the point of a heat protectant.
