Kiss Colors & Care Permanente Kleurveranderende Shampoo Kleuring - Donkerbruin | Permanente Shampoo Kleuring, Verhelderende Shampoo, Sulfaatvrij,

I’ve tried box dyes for years, but this shampoo form is so much easier—just lather it in like my regular wash and the dark brown came out even and rich. It’s been three weeks and my color still looks fresh, plus my scalp feels cleaner without that drying after-feel I usually get.

Three minutes in the shower and my grays were actually gone—the dark brown came out even and natural, not patchy like I feared. It's been almost four weeks and the color's still holding, though I do have to use it more often than the six-week promise suggests.

I was skeptical that a shampoo could actually color my hair, but after three minutes in the shower, my grays were completely covered and my hair felt softer than with my usual dye. The sulfate-free formula didn't strip my color, and it's been holding up beautifully for over two weeks now.
