A preliminary patch test is recommended to ensure no skin irritation occurs during application. 

For patch test: Apply an equal mixture of Parts 1 and 2 on a small cleansed area behind the ear or the fold of the elbow. Wait 24 hours. If irritation occurs at any point, wash the tested area with soap and water immediately and discontinue use. Do NOT proceed with an application if irritation has occurred. 

For application: Ensure hair is dry prior to use. Apply an equal mixture of Color Reverse Parts 1 and 2 to desired areas of hair. Cover hair with a plastic cap and leave Color Reverse in for 20 minutes. Lastly, shampoo hair and rinse thoroughly for 5 minutes. Repeat this step 1-2 more times. For best results, apply Satin Color Care Intensive Conditioner after Step 4. Leave in hair for 10 minutes or 5 minutes if using heat. Warning: Do not use the product on eyebrows or eyelashes. 

For external use only. Do not ingest. Avoid contact with the eyes. If contact occurs, rinse thoroughly with water and contact a physician. Keep out of the reach of children.
