"If you have a short , fine and Grey hair front part of hair line, it may not work great.I used 5G and I applied it and it didn't work. I even rub on my hair too. As it show on the video. IT DIDN'T COVERED MY GREY HAIR AT ALL. It is so liquidity it keep running down on my face. Smell is horrendous and if you use it do it on Friday night and don't plan to go out during weekend.I gave 2 stars because it was easy to use.If you buying first time just purchase one cartridge because you going to go through a heck of time to return that cartridge.Last thing is there is a set of glove with this product. I have small hand and it was so hard to fitted into that glove."

I’m genuinely so happy with this product! It made applying hair color so much faster and easier than I expected. The whole process felt more manageable and less messy.For the first time ever, I was able to color my own hair completely by myself! That alone says a lot about how user-friendly and effective this is. If you’re looking for something that simplifies at home hair coloring, I definitely recommend giving this a try. It made such a difference for me!svetlana

I’ve been coloring my hair at home for many years, so I appreciate products that aim to simplify the process. What stands out most to me about the L’Oréal Colorsonic is the convenience factor.Mixing dye and developer has always felt like the most tedious step, especially trying to make sure everything is measured correctly and blended well. The fact that this device handles the mixing automatically is such a smart idea and takes a lot of the guesswork out. I also love that it’s designed to minimize mess and make application more straightforward.What Customers Talk About
