Just for Men Shampoo-In Hair Color, Ash Brown 20, 1 application, (Pack of 3)

I use this color (Ash) for my dark brown/black hair. I can't use the other colors because it turns my hair Red. You just leave this in for 20 minutes. It darkens to the right color. You can call Just for Men and confirm this..they are the ones who told me this if I have the red color issue.

I've now tried several Just For Men colors. They are all good for a few days, but within a week or two the results are always the same.
Copper!
It'd be fine if the dyed hair simply went gradually back to gray, but no such luck. As the color fades, orange is left in its place. It doesn't matter if I use medium brown, dark brown, darkest brown, ash brown... Orange, orange, orange are the results. And each time in between i waited several weeks to grow out the previous copper before i planted a new Just For Men in order to grow a fresh crop of orange.
Haven't you seen men with copper hair color and wonder why they would dye their hair that color! It's not them, it's the product!
This review is for all the men who slink away thinking it must be something wrong with them or how they applied the product. No, no, and no. Should be our response. This product is not the answer for us.

This is a great color - I have a hard time finding it in stores. Only CVS seems to have the Ash Brown. Walgreens, Rite Aide, Target, Safeway -- none of them carry the ash brown - at least none of the stores near me. The price on Amazon was about $1 cheaper per box than what CVS's regular price is. This is a good color - the "ash" in the brown helps make the color look more realistic than the medium or light brown colors. Problem is that within a week, I see gray strands popping up on the sides and top of my head. Ideally, I'd have to use this product every two weeks to stay on top of the gray. I use a shampoo that is formulated for color treated hair, but even still, the color just doesn't last anywhere near what they say it should.
