Anonymous: I'm in cosmetology school, and my friend wants to me to do her hair. She is naturally a level 4, with some red tint. She has about two inches of roots. She has been coloring her hair a 7cc and since the color is so bright it fades quickly.. She is asking to to coloring her whole head so it's bright again. Any specific way I should apply the color, as in mid strand, ends, roots. And should I use a different type of developer for her roots and the hair that just needs the color brightened.
I would do her roots first like you were doing a root touch up with a 20 developer. When you’re done with that start doing mid strand to end. & once her roots are done you can wash it out
