Schwarzkopf Keratin Color® 1.8 Ruby Noir Permanent Hair Dye | Up to 100% gray coverage, Bond Enforcing System, Strengthens and softens, Even-toned vibrant result, Deep nourishing effect

I absolutely loved using Schwarzkopf Keratin Permanent Hair Dye Cream in 1.8 Ruby Noir! The color came out rich, vibrant, and multidimensional with the perfect deep ruby tone. My hair felt soft, shiny, and surprisingly healthy after coloring instead of dry or damaged. The application process was easy, and it covered my grays really well. I also noticed the color stayed vibrant for weeks without fading quickly. If you’re looking for a bold color with salon-quality results at home, I definitely recommend this one!

I’ve home-dyed and salon-dyed my hair for 15 years. For box dye, this stuff is as good as it gets. The color is rich and it lasts. It’s hard to find rich, beautiful red tones in box dyes, but I’ve stuck with this brand since I found it. They even adjusted the formulas in the last year or so, such that it no longer leaves any temporary stains in my shower. Even with the old formula that did stain, the stains always rinsed out on their own after a few weeks of just regular shower use. So don’t panic if you see them at first (I rent, so I’m always nervous about accidental damage.)

Quick background on my hair and I'm sorry that my review is very lengthy! :) My virgin hair is black/brown, 3/4th of my hair was virgin, with the last quarter of hair being a slightly reddish brown color from previous colorings. The length is at my mid back, and with semi thick hair. 1 bottle did the trick, did not need two. There was a fragrant pretreatment serum that you can apply to dry ends before applying the color which was very nice; something I don't see in a lot of other box dyes. The leave in conditioner smelled very nice as well and was very effective. My newly colored hair versus my virgin hair feels very similar. The ends are surpringly soft as well! When you mix the applications together, it first was orange, it alarmed me! But rest assured, the color will set into a dark red. If you want to go for a subtle look (dark red/black without light, then rich vibrant red shining during light/sunshine) then apply for 30 mins. If you want the red to show with light and more of it during light/sunshine, then apply the color for 45 mins. I applied it for 30 because that was the amount of time written on the instruction manual, but I wish I went for 45. It came out very red/black, but it did have such a gorgeous red coming through when my hair was exposed to any light source. Overall, I'm very pleased with the subtle look. But that's why it's unfortunately a 4 star and not a 5. It takes a while for the initial application to wash out of your hair, I washed it out for 15 mins and still had some red water coming out. Please be prepared to get at least one towel/rag/unwanted t-shirt stained. I read that this color keeps washing out of your hair so I was prepared for it, and the other reviews regarding that were correct. My old rag/towel was stained from wrapping my body with it when I first came out of the shower with slightly red water still coming out. Once I blow dried my hair, there were no other stains or color rubbing off onto anything. I slept with an old unwanted t-shirt covering my pillow case just as an extra precaution but there were no more stains. If you generally want a more lighter red on your hair, I recommend getting a different box due, or applying this color to naturally light colored hair, or hair previously colored to a lighter tone. My hair is very dark brown, basically black, and although I ended up liking the subtle look, if you are looking for bold colors to apply on Dark/Black Hair, I think this box dye might not be the best choice to provide such results. Again, I love the results, but the Noir part of this Ruby color, couldn't provide the rich red pigment onto my black hair. I wish you the best of luck!

Love the colour! It does bleed a lot, as most reds do.

perfect color and easy application

This color is great on my hair which is very dark brown with red sort of undertone naturally. It looks like a really dark color when in normal light, or in the dark, but in the sun it has a fiery red highlight and I love that. I wash my hair every other day, so no, it doesn’t last long and I have to redo it a lot, but that is because of the frequency of my hair washing. It will last through the amount of washes it claims on the box, I just use them up fast. When it fades a bit the highlight isn’t as red, but it’s still there. I have never seen this color in any other boxed dye. If your hair is drier, condition your hair really well after using. Not just with what’s included, but get a good conditioner. I have very dry hair, all dyes make that worse. If you are sitting in the sun, it will look dark where the sun is not hitting and red where it is. I think that’s awesome. One more thing, when you apply it, it will look pastel pink after you first mix it, it will turn orange on your head while processing, then it will turn dark purple and it rinses red like someone has been slaughtered in your shower, and if no one has, then it’s just the dye has changed completely. but don’t let all this change make you think you were sent the wrong dye or worry you. The first time I mixed it and it was pastel pink I thought I might have bought the incorrect color. But that’s just how it is.

I have found this brand to be pretty intense. I love this color, dark blackish ruby red, and it came out true to what was advertised on the box. It also covered every single grey and never faded. However, I was still wringing the color from my hair 2 months after I initially dyed it. The water from my hair still had a slight red tint to it. I've never experienced anything like it. It's crazy because this dye never left stains on my skin when I applied it and washed it off. I would expect it to with that kind of staying power. After wearing this color for several months, I decided to dye my hair back to a 3 black/brown in a different brand of box dye and could still see the ruby in my hair after a couple of full dye jobs. I decided to use this brand again, but in a dark brown to try and counter it and it seemed to work but since this brand seems to be rough on my hair I won't be using it anymore. 3 stars for a true and beautiful color but minus 2 for the neverending bleeding.

Great!!! Colour and shine, doesn’t damage and was cheap!

Didnt do much for my hair ( dark brown) but it made it really soft. Not a heavy smell and condionner is really good.

Used two packages, I have a lot of hair and it’s long. The color is stunning and even. My go to and it always looks salon beautiful.

It’s a very nice shade of red regardless, but the shade isn’t as dark as it is on the cover of the box so don’t let that fool you. But also don’t let it stop you from buying it either because you can just go over it with some black semi-permanent hair dye to make it as dark as you want like I did a few weeks after taking those pictures. Very nice red, but remember 1) permanent box dye is bad for your hair 2) permanent box dye is hard to get out (ESPECIALLY RED)

I have had a hard time finding this colour anywhere. I just about jumped for joy when I saw it was available again on Amazon and I also finally got to use it and my hair turned out great.
