I have a lot of white hair and use 1.0 Natural Black. It covers it perfectly with one dye application, and my hair is fairly long too. Like all black dyes, after three months without coloring it—as in my case—it’s natural for the roots to show, and black dyes also turn reddish, like black cats that take on a rusty hue. The dye is perfectly good and doesn’t make my hair feel like straw. Now, if you want a dramatic change or a very intense color, put lots of chemicals on your head and fry your hair, or go to a hair salon. These things aren’t done at home. At 43, since I’ve always had intense black hair, I like KORRES’ Natural Black, which doesn’t come out jet black, at this age.

Very good hair dye with an even result and a strong color that doesn’t fade. On natural dark brown hair with a few gray hairs, I use the corresponding dark brown shade and it comes out perfect, vibrant and shiny. For older people with lots of gray hair, dark blonde comes out like light brown; in other words, blonde shades turn out much darker on completely white hair. But once you find the right shade number, it’s perfect—I wouldn’t change it for anything, and it doesn’t damage the hair like other commercial dyes, which tend to dry it out, cause breakage, and make it thinner over the years.

It’s very good for the skin and doesn’t irritate me at all; I have sensitive skin, BUT only shade 4, which is a basic color, covers my hair completely. The dark chocolate shade turned quite a few white hairs copper, while the rest was brown. I wasn’t satisfied with the coverage.

I like these hair dyes because they’re gentle on the hair; they don’t make it rough.
They’re also the only dyes I apply straight from the bottle... No mixing bowl is needed

It makes the hair horribly sticky and stiff. What a crappy conditioner the box contains—it just smells nice but does nothing. Terrible, a waste of money, and they pressured me into buying it; I don’t want it. Better to get €3 Palette dye from the supermarket than this hair-dye rubbish. What a shame after all the advertising. They’re mocking ordinary, poor people, while they become millionaires selling this trash. They don’t say what they put in instead of ammonia, which is essential. That ingredient makes the hair sticky, stiff, and dull

I have been using this dye for years. It covers gray hair. No problem. Bonus is the excellent mask they give with it.

The color is quite natural, but it didn’t cover 100% of white hair. I dont have a lot, but it is noticeable. Also, after 4-5 washes it seemed like it actually revealed more white hair (as if the dye washed off them), and it’s a totally unacceptable result for a dye that claims to cover them?

I don't know if the color will last. But for me, where other dyes caused allergies and itching, with this one I feel nothing! So 5 stars for that!

The shade on the hair is quite different from what the box shows, it comes out darker (of course, it definitely also depends on the base-existing color). Like most herbal dyes, it does not have the same duration/resistance as regular ones. However, it is friendly to the hair, so just for that reason alone I continue to prefer it.

The dye is very good, without having a bad smell or causing me the slightest discomfort! The result is very good, now as for the durability of the color over time, we will see..
