If you have thicker or longer hair, use two boxes to ensure full root-to-tip coverage. *Against combing breakage on damaged hair vs. a non-conditioning shampoo

Review: Best hair color ever - 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!
Review: Good colour and feels healthy - I have been using Clairol from Sally's Beauty for years, and in more recent years found it just stopped covering my greys...even when I switched to the grey coverage. So I went looking for another brand, hoping to find something still relatively chemical free and came across Schwarzkopf. Now, this stuff doesn't make my eyes water and tear up near as much as some other brands (I got Revlon once, and have had professional colouring done twice), but you definitely still need to ventilate the bathroom when applying. I purchased two boxes, one in Rich Bordeaux and one in Rich Caviar. The Bordeaux I applied, i've always done reds or some natural henna in the past...and it worked wonderfully on all my whites/greys and all my new hair growth (been a good year or more since last dye used)...but it only coloured some random strands past the new growth. So that may have been previous colours causing an issue or user error for application. So, rather than buying another box, I went ahead and applied the caviar- and my hair looks great now! There's still some more reds throughout from the bordeux, but the caviar got anything that hadn't coloured previously in addition to blending well with any of the bordeux. My hair feels nice, not damaged like the more chemically brands, although I still desperately wished the Clairol worked because that caused no tearing up whatsoever. I am inclined to think regardless of my previous colour and application skills that I just need two boxes given how much hair I have, so user beware if it's more than a touch up- full head coverage- and you have long and fine hair you should have two boxes ready in case.
