Engineered as a canvas strengthener, the K18 Pro Mist is the pre-service step made to strengthen hair so it can withstand the chemical damage that will occur during color. This allows the color to go further, last longer, and leave clients with the strength, softness, smoothness, and bounce like new. We recommend following-up with the mask to maintain the integrity of hair as you continue to style it. Damage is ongoing so use of K18 should be too.
