What every shampoo should be
I hate washing my hair, absolutely dread it and this shampoo is my new best friend! I only have to wash my hair once a week, it's not too drying, it gives really good volume and I can literally feel how clean my scalp is after use - which is such a weird thing, lol. I'll never be able to not use it. My hair is a little more on the dry side with heavy blonde highlights, I use the K18 Shield conditioner with it on wash days, air dry and use the k18 hair oil everyday. Super simple hair routine to keep my long blond hair healthy and frizz-free.

I AM RAVING ABOUT THIS PRODUCT!!!!!!!!
I’m my hair felt heavy, it was super hard to comb it felt stiff like hay but I haven’t been using heat products so there was no way it was from styling. After a little research, I decided to try this product and I am so glad I did. It makes my hair feel so good compared to other “detox” shampoos. My hair feels like it never felt before. It feels light, airy, and best of all I have my volume back. Will continue to use this habitually I’m so glad I found something that works.
