Maggie Dark Green is a rich and vibrant emerald hue that will leave your hair looking brilliantly bright and bold. All of our hair colors are: • Semi-permanent • Vegan & cruelty-free • Ultra-creamy conditioner based • Without harsh chemicals, such as ammonia or hydrogen peroxide • Mixable & DIY-friendly USING: Apply a thick layer of Maggie Dark Green hair dye on dry, unconditioned hair and leave it in for 60-90 minutes. For longer lasting results leave the color for 2+ hours or even overnight. Our hair colors are conditioner-based, so they nourish your hair like a deep conditioner while you color. Rinse with lukewarm water and enjoy your intense deep emerald green hair color, that will last up to 12 washes (results may vary depending on the base and condition of the hair, duration of the color and hair care products).
