The ADF color conditioner is good stuff and does what it claims. You do have some control over the degree of coloring based on how much you apply and how long you leave it on. It's a temporary solution, though--- the color won't really last through more than a couple shampoos. However, you don't have to use that much so it's not that big of a deal to buy a bottle and comb some in and re-do it every week or whatever to maintain an aging piece.
