Just For Men haircolour blends shades of your natural colour into your grey so subtly, no one can tell where the grey was! This thick, no-drip haircolour is easy to shampoo-in. It stays put. No mess. Grey is gone in five minutes - the time it takes to shave or shower. Just For Men haircolour won't change your natural hair colour. It actually targets grey and blends in several close, but slightly different shades that match the rest of your hair. Fortified with vitamin-enriched conditioners, proteins, chamomile and aloe, Just for Men gives healthier looking hair that's easier to control and looks great. One application lasts up to six weeks. It won't fade or wash out but lasts until the grey grows back. To use: Apply, wait five minutes and rinse out. Full instructions included.
