Well I apply color oops on my black hair, and I was very happy with the results the color black disappeared, my hair was kind of light red or copper color, but it wasn't even, so I went to the beauty salon to dye my hair , the hair stylist said I will apply something lighter than what you really want because the color will turn darker , so she put a very light brown , my hair was a mess the roots were light and the rest was really dark almost black. I got really mad so I went and apply one more time the color oops and now is light brown, but is not even, what can I do ? I'm scared to dye it? Is it going to get dark again?

Please help me... can I use something (like color pulse) will that make my hair all one color?

If your hair color looks uneven, you probably didn't distribute the hair color mixture evenly through your hair. You will need to re-color your hair in order for it to look consistent. However, you don't have to apply hair color all over your hair, you can just re-color the uneven sections of your hair.
