Pravana ChromaSilk 000 Lightening Booster 3oz

This low-level ammonia formula preserves the integrity of the hair and allows colors to perform both as permanent and demi-permanent simply by using different ChromaSilk developers. PRAVANA's ChromaSilk Creme Haircolor #000 Lightening Booster can be used as a demi-permanent dye or permanent color depending on which developer you use. You also don't have to worry about frying your hair if you do multiple treatments- as this product contains proteins for ultimate protection and shine. How To Use: In a non-metallic bowl- mix one part permanent color with 1.5 parts creme developer 10-40V (1:1½ )- and apply color. Process for 30 minutes -- up to 45 minutes for gray coverage.
