Very convenient especially when traveling, you can just take one of the package and they are easy to use 😀.

So easy to use anyone can do it just shampoo in leave on recommended time and shampoo out. Grays are gone!

Muy facil de aplicar no mancha la piel y no irrita ni maltrata el cuero cabelludo.

so wonderful to make the hair supple and black for a long time than other dye product. I will come back .

I wanted to love this, as the ease of a shampoo dye is much easier than regular coloring, but it made my hair feel horrible, like straw. I couldn’t get my finders through my hair when i was rinsing it out. And on top of that, it did not cover my greys or color my hair much at all.

This stuff works very well. I was disappointed I had to keep it in as long as regular hair dye but it seemed to have a very strong pigment and covered all my grays very well. It was a but pricey, at $24 so I'm hoping I can get at least 3 uses. I have tons of hair but only use on my roots.

Does not work well. Applied many times but always comes out 70% black. Looks black when applied but some wash away when showering.

Effective, works and is safe
