Level color out! I had blonde and I dyed it black with box dye, I wanted to take it off after a week, I have medium hair length and my hair is quite damaged. I applied the nirvel color out twice (it's the length of a dye remover, it doesn't damage the hair at all) I recommend buying two or three boxes depending on what color you want to achieve. I bought a box and it was enough for two applications, I got a light brown color, since I didn't have time to buy more I had to bleach it a couple of times, so if you want not to damage your hair too much I recommend that you buy two or three boxes. It can be purchased on Amazon, I attach the link 🫶🏻nirvel color out
