Just For Men Shampoo-in Hair Colorant actually blends shades of your natural colour back into the grey - so subtly your can't tell which hair used to be grey. And it works so quickly, so gently, it doesn't strip out or change your natural colour like most leading hair colouring products do. Its unique natural look formula actually targets grey hair and blends in several close, but slightly different shades that match the rest of your hair. Grey is simply blended away. Even you can't tell where the grey was. And now, Just for Men contains extra conditioners for thicker, healthier-looking hair.
As easy as shampooing. Mix, apply, then lather in. Wait 5 minutes. Rinse One application lasts up to 6 weeks.
