American Crew grey blending doesn't require a special visit to the salon, with foils and long waits at the shampoo bowl. Most of the techniques can be performed in less than four minutes. And the colour needs just five minutes to process on the hair.
Precision Blend is a camo colour also known as salt and pepper, it takes some grey and leaves some grey making the colour look more natural. There will be no regrowth which prevents the colour looking artificial and it won't develop to a warm shade.
