The color is so beautiful, and the machine makes it so easy to apply. Usually I leave dye in 45 minutes for resistant hair but I followed the directions and did 30 minutes with perfect results. The dye even covered some brassiness that was left from the last box dye I used. I did not even need to use toner or blue shampoo afterwards! It did come out a little light in my opinion, but it looks so good I don’t care!

Color is fire. Love it.

okay sooo - i love fresh color and i swapped to box coloring my hair during covid. i always go a true black, but my hair is dark brown, so every few months i get that clear line at my roots where my hair is growing out. this device makes it SOOO much easier!! i love that i just plug in the cartridge and i don’t have to mix anything any more. i used to leave a huge mess in my bathroom and would have to spend a while cleaning up. i used the 2AA cartridge and my hair looks very deep black, just the way i like it. 2 weeks later and it still feels true black, with some other brands it looks red in the sun, which i can’t stand. its super quick & comes with this blue cartridge in the box which you use to clean the device after, i just left it in the sink to run through, was easier than i thought it would be. excited to use it again

Wow. Easy to use and looks great. No missed spots on the back of my head.

I likes it. It was fast and easy. Suggestion- Please produce the L’oreal Hi-Color for dark hair cartridges. Please. Thank you.

Don't miss this ! I colored my hair in 5minutes and even my friends commented how gorgeous my hair looked. No mess, no drips, easy and with great gray coverage . I did not needed to part my hair before coloring... I just brushed before coloring and I was ready to go. I loved how easy it is to apply and that I can save whatever is left inside the cartridge to retouch my roots - great value for the money. I can apply and re-apply multiple times with the same cartridge. You know that bad ammonia fragrance we get with some other colors?? Well! Forget it with this one. True game changer! Loved in all ways and I recommend to all. Don't get fooled by some reviews.... thank you L'Oréal !

I loved how easy and mess free is to color my hair now. I applied in less than 5minutes and i still have half of a cartridge left! It has been 3 weeks and my color is lasting so well.... so brilliant and with great gray coverage. I loved the little box it comes with... it fits perfectly under my sink. I will for sure get another cartridge soon!

I was hesitant, but so happy I tried this. I used shade 7, the color is GORGEOUS and shiny. The device made it easy to apply just to my roots and color blended nicely with the rest of my hair

Easy to use. Happy with the results and many compliments about my hair color and shinny appearance. Covered my gray hair.
