INSTANT GREY BLENDING. Tones down grey for a natural, blended look in 1 use. For guys who want to keep some of their grey, Just For Men® Touch Of Grey® blends away a little grey, but not all of it. With this easy, no mix, comb-in formula, all you need is 5 minutes to instantly have a more balanced, naturally blended salt and pepper look. Lasts up to 8 weeks until the greys grow back. Can't decide between two shades? Try the lighter one first. You can always go darker later.
