My favourite
My favourite colour. Been using this one for a few years now, it's so exceptionally lovely. The perfect reddish glow in the sunlight, and the colour lasts for many months before fading. I usually only have to colour my hair every 3-4 months, but I'm going to start doing it more regularly bc I'm getting a few greys lol. This colour covers the greys completely by the way! :) This colour does bleed, but it's nothing too dramatic. Just keep a dedicated towel that you use only for drying your hair with. I use a dark brown towel and you can't see any stains on it at all.

Schwarzkopf Keratin Color 4.0 Cappuccino – Nothing Short of a Salon Experience from a Box
I am impressed. This permanent hair dye delivers beautiful, rich color and a true salon-quality experience right at home. The shade 4.0 Cappuccino matched the model photo exactly—no surprises, just the warm, dimensional tone I was hoping for. The scent alone feels elevated; it has that recognizable high-end beauty salon aroma you find in a salon in Beverly Hills. Results exceeded my expectations in every way. Color payoff, coverage, and overall finish were outstanding. Highly recommended if you want professional-looking results without the salon price tag.

Love 💕
Love the product, easy to use, and great turnout. I would say if your hair is two-toned, the lighter parts will take the color more. The overcolor is beautiful, a lot darker than I expected but I know it will wash and fade lighter so I'm not upset! I will be repurchasing when it comes time to dye my hair again! 💕

curls beware only for straight hair - dont chance your curls for color
update: Most unfortunately and Im devastated as the color was great , but ever since this process my natural curls have disappeared… to what is now straightish frizz and bog hair . Even with the best of the best of curl products, im still in shock that only a curling iron will give my hair any definition, and it doesn’t hold for more than an hour.. After 10 years of japanese straightening, I had finally embraced and was loving my curls -and now they are gone.. and it’s not like my hair is pretty straight and pretty.. it’s everything but , apparently in order to reverse the damage , i cant treat or use any hot tools, or all the expensive “fixes” I bought because it never occured to me this color treatment was the culprit- not product buildup, not hormones.. I didn’t need to buy a brand new hair blower with a diffuser, and all of these curl enhancing products by Moroccan oil, no matter what I do until this grows out my hairdresser told me I am stuck in limbo and not the fun kind at a party.. so I won’t erase my review as if you have straight hair and don’t need to worry and this is the color for you, but curls beware!! unfortunately, I’m still going to be on the search. I don’t know what I’m going to do to cover the Gray, in the meantime of trying to revive my curls .It really is upsetting to have your hair ruined with no known timeframe of when it may return to normal. but here is the review for color if and only if you have straight hair. Exact match to not only the color shown on the box , but also to my natural hair color . Silky and shiny for the first time after coloring it in a year . I have been using the Igora product line including permanent, absolute, and vibranceas well as trying different levels of developer. I kept thinking I had picked the wrong color- always dry after ranging from too dark, to orange rather than auburn which apparently is “copper” . Even worse what was supposed to be the golden or highlights or red - always would end up ONLY on the top of my head where regrowth was , not covering the grey I was dying it for in the first place , and no matter how perfectly applied with both technique and time left on would only leave the rest if my hair dry and a drastically different color then the top of my head . My instinct was to try this over and over again, and yet the Reviews would always lead me back to another try . This is absolutely the only color I will be using from now on . Forget about the hundreds of dollars I spent on all of the separate products within the same line not to mention a large price difference for each individual product versus this fantastic all in one. The directions here are clear, concise with no questions left un answered. Down to rinsing it with water and using their conditioner rather than washing it after dying. I can’t believe how soft,shiny and lovely This color is . Not to mention it’s name is actually appropriate to the color as well as the picture. Its not too dark , doesn’t call it blonde when it’s brown and doesn’t call it brown when it’s black . It is miraculously back to my original medium brown color and somehow even has my natural highlights I always loved that glisten in the sun. Basically it feels like I never dyed my hair, which is exactly what I wanted , it covered the gray impeccably. There’s not one grey hair in sight for the first time in so long even after dying it fresh over and over again. Its by the same brand as all the other products I had to get because of it being marketed as “the best” , but blows them away in every aspect important to anyone coloring only because of grey and with the frequency necessary to be done at home vs the salon . Dont hesitate brunette beauties- get this!

Excellent product
It took me a while to find this product, I've tried a lot of the affordable do-it-at-home brands and they were a disaster. The good: This product is affordable, doesn't stain the skin, doesn't stain the tub, easy to use, right consistency, perfect color, covers grays 100%. You get a generous quantity of the product (I have medium-long thick wavy hair and there's enough product to cover everything, and more). The espresso color is very natural, it's the darkest brown before it's black, so it doesn't have the metallic cold sheen that black does The smell isn't deadly, it's tolerable. The pre-treatment for dry ends is my favorite part, and the conditioner smells very good and seems to be a good quality. The bad: The gloves that come with the product are very krappy. They don't provide with eyewear arms protectors (an absolute must for all Home kits). The product (as expected) will stain fabric and plastic eyewear.

The absolute best
I’ve used every brand of ash blonde hair color and this is the best. It’s moisturizing and the color is vibrant and fabulous. My hair feels so healthy after using this. I dye my hair once every four weeks. I probably could go 6 weeks but I like my hair looking good. This brand is wonderful and I will continue to use.

Left Unclean Residue Texture in my Hair
I have always wanted to try this brand hair dye but it’s always been a bit more expensive for me to buy two boxes compared to alternatives. I was so excited to finally try this dye in the color Espresso which is a rich cool toned dark brown to almost black shade that’s exactly what I was looking for. I was hoping this color would offer me more dimension while providing a overall, even color consistency but sadly neither of those are true. This color ended up looking pretty flat and one dimensional on my hair, and there’s areas of my hair where the dye did not absorb as evenly or as dark as other areas leaving my hair looking very ‘at home’ done. I’m a former hair dresser so I’d like to think I did a descent job if thoroughly and evenly covering all my hair consistently the best I could. The worst part about this hair dye though is that ever since I dyed my hair, my hair always feels really dirty and greasy feeling now, which I’ve never had happen before. I washed my hair yesterday for example and it already looks like it has greasy strands in it and needs to be washed. This dye left a very strange texture and unclean feeling to my hair that I can’t seem to get rid of although it’s been several weeks since I dyed it now! Comparing it to other products I use to dye my hair, this one is definitely not it for me, but I’m glad I tried it to see what I’m not missing out on.
