I was surprised!

I brought this little sample on vacay with me (a great way to travel light) and was surprised how clean my hair felt after I used it. I use a lot of product on my curly hair and I felt this was a great reset for my hair. I’ll definitely buy a bottle of this shampoo with my next K18 order!

Easiest Hair Care EVAH!!

One of my favorite things that I love about the K18 hair system is that it is easy! The fact that I don’t have to rinse out the spray, the conditioner, or the oil is a lifesaver because it’s a timesaver. I love this shampoo and the entire K18 collection!!
