Mix COS in an applicator bottle or bowl. Equal amounts of part 1 and part 2 must be mixed together for 30 seconds. Secure a cap on both. Apply to dry hair that need hair color removal or correction. Place cap on hair, clip securely and process for 20 minutes. Rinse for 10 minutes with warm water. Shampoo a minimum of 3-4 times after rinsing. Check for color removal.
