Subtle copper highlights! First, comb the hair back before applying the frosting cap tightly onto the head. Use a crochet hook to pull the hair out of the frosting cap hole and comb the hair. Next, mix the bleach powder and developer to a sour cream or batter consistency, and apply it onto the hair that was pulled out of the frosting cap holes. Wait for the hair to lighten and wash the hair with the cap still on the head if you decide to tone it. Tone the hair and wait for color development. Remove the cap and rinse the hair and style. This how to use the frosting cap and highlight the hair is produced by BeautyHealthTravel channel with guest artist M. Lahham, for cosmetologists, beauty school students, hairdressers and salon professionals.
