This thick, no-drop hair colour is easy to shampoo-in. It stays put. No mess. Grey is gone in 5 minutes-the time it takes to shave or shower. Just for Men won't change your natural colour. It actually targets grey and blends in several close, but slightly different shades that match the rest of your hair. It looks so natural, even you can't tell where the grey was! Vitamin-enriched conditioners with a unique complex of vitamin E, protein, chamomile and aloe for thicker, healthier-looking hair that's easier to control. On application lasts up to 6 weeks. It won't wash out, won't fade out, no matter how often you shampoo. Lasts until grey grows back.
