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.
