Wearing suitable gloves, apply to wet hair, lather and rinse well. Leave on 3-5 minutes for maximum cooling effect.
Important: In case of contact with eyes, rinse them immediately. Designed for levels 1-4, Dark Envy should not be used on white or grey hair as it can leave a greenish hue. This also includes any hair that has been lightened to level 5 or lighter with colour, lightener or the sun.
