THERE ARE TWO WAYS TO PROCESS SPARKS COLORS
OPTION 1: For maximum color vibrancy and durability, you must pre-lighten hair as described below. Pre-Lighten hair with SPARKS HidraColor Powder Lightener and SPARKS HidraColor Creme Developer.
OPTION 2: SPARKS colors may also be applied to virgin hair or to hair that has been previously colored but not lightened, however, the color will not be nearly as vibrant nor will it last as long in the hair.
APPLICATION AND PROCESSING1) Before applying SPARKS, hair must be freshly shampooed and thoroughly dried.
2) Do not mix SPARKS with any developer or peroxide. Apply the desired color directly to the hair.
3) Process for 20 minutes at room temperature.
4) Thoroughly shampoo and rinse from the hair until the rinse water runs clear.
