Blondes beware
This ruined my hair and caused so much breakage. It’s a tiny bottle yet somehow caused so much damage. I am so sad, my top layer looks awful, and I’ve never had a product so so much damage!! I have dirty blond hair with blond balayage and I’ve had this done for years. I was shocked how within a few months the of using this product how quickly it destroyed my top layer.

Shockingly little product
I love K18 and the dry shampoo changed my life but I would pass at least on the mini version of this. It’s shocking how little comes in this, I used it four times. It made my hair soft but I’m not happy about the price and the amount.
