I've used Just for Men dark brown hair dye for years. Always with great results. Not the same. No matter how many times I used the shampoo the results are what my wife calls " mouse brown". I think I'll switch back to the dye.
I purchased a tube and shampooed for several weeks. It worked wonderfully. The shampoo changed gray/white patches black. Does stain shower and nails, use gloves. I recommend the product.
Not working well at all.
Product stains your hands even when just using your palms as recommended, I've had to use nail rush to try and scrub it off, also after 3 weeks, I don't see much of a difference. I don't think this product was ready to be marketed yet.
