Keratin Root Permanent Hair Color Kit, 4.0 Dark Brown, 1-Application Root Touch-Up with Collagen & Vitamin B6, Complete Gray Coverage, Precision Brush, All Hair Types & Textures

I loved this root touch-up hair dye! It’s super easy to apply and gives 100% gray coverage. The best part is that it only takes 10 minutes—perfect when you’re short on time. It leaves my hair soft, shiny, and healthy thanks to the keratin and collagen. The black color looks natural and lasts a long time. I’ll definitely buy it again!

As a recent DIY hair colorist, I have been trying out my various options. I ordered, and was impressed by, this product. As usual, I preread the instructions to ensure that my application process progressed smoothly. Here are some of the positives: 1. Keratin pre-treatment seemed to seal in the hair color and ensure against possible hair damage; 2. I used clips to separate and treat each strand -- the color applied smoothly and disseminated well using the application brush; 3. I applied extra color for those stubborn greys, and was glad that I did when the final unveiling occurred; and 4. The gloves were more sturdy and substantial than many other packaged products. It has only been three days since I applied the color, but it seems to have taken well. Further, my hair is smooth, shiny, and less tangled in the after-care process. I am glad that I ordered several boxes, as this may be the winner in my selection process.

This company has developed a wonderful product. It leaves my hair feeling great and the coverage is wonderful....much better than other top named products. I took a chance on this company and it is a winner. The problem tho, to get the regular dye, is hard to get. They don't make a lot of shades, unless you are a blond then you are all set. But I will keep trying to find my shade. The color is just perfect, without leaving different shades to your hair. And it lasts thru more shampoos than another name brand.......LOVE IT.

I’ve tried several root touch-up products, and this one from Schwarzkopf is definitely one of the best. The Keratin Color Root covers grays quickly and blends seamlessly with my natural hair color. The formula is gentle, doesn’t leave my hair feeling dry, and adds a nice shine after use. I also love that it lasts well until my next full coloring. Very easy to apply, with no mess, and it gives a natural result every time. Highly recommend for anyone looking for reliable root coverage at home!

I'm impressed with the Schwarzkopf Keratin Color Root Permanent Hair Color Kit! The application was easy, and the results are amazing. The color is rich and vibrant, and it covered my gray hairs perfectly. I love that it's formulated with keratin to help strengthen and nourish my hair. The scent is pleasant, and I didn't experience any irritation. The color has lasted well, and my hair feels soft and healthy. Overall, I'd definitely recommend this product to anyone looking for a reliable and long-lasting hair color solution.

Like it the issue is it say keep it only for 10 mins . I have a stubborn gray thats why it didnt cover my grays.

I really liked the color. Matched perfectly. It was so easy to use too. No mess. The price was right. I should have purchased 4 or 5 boxes at the $6.00 price. I'll continue to look for another sale on it
