The most unique feature of this hair color product is the ability for the package to mix the colorant and developer as the product is being applied. The consumer simply exchanges the flat shipping cap on the bottle for the mixing/dispensing cap. Depending on the length of the hair to be colored, enough product remains for a second full application or touch-up. The video on the manufacturer’s website is very informative and demonstrates how to use the product in great details. This column will attempt to review the ingredient listing for functionality and claims substantiation.
