INSTRUCTIONS:
1 Apply generously to freshly shampooed, towel dried hair (for strongest results apply to clean, dry hair)
2 Saturate hair thoroughly (goop it on there!)
3 Leave on for 5-30 minutes depending on desired color intensity. The longer it's left on, the darker the results. Color will never be as dark as the color of the product.
4 Rinse hair in cool water away from face and body.
