Just For Men® Touch of Grey is for men who want to look their best but don't want to get rid of all their grey. A little grey shows experience, but not so much that it hides vitality. It's the first no-mix, no-mess system, as easy as combing your hair, and takes just five minutes. Just For Men Touch of Grey works gradually giving you total control: with each application, you control how much grey goes. The formula is gentle and long-lasting with no ammonia and no peroxide. This natural look lasts for up to six long weeks. Touch of Grey comes in a range of natural-looking shades. Can't decide between the two? Try the lighter shade first. You can always go darker later. It blends away some grey but not all. One application reduces grey a little. A second pass will get rid of even more grey. It's pre-mixed, just comb-in, wait 5 minutes, and shampoo out. It will not wash out and lasts up to 8 weeks until the grey grows back.
