Hi I dyed my hair about a year and a half ago black.Recently about 2 mnths ago I dyed top of my hair brown and bleached bottom half of my hair. It was OK but part of my top hair is brown and the ends are a dark brown to black. My roots have came out a lot some of my tips from the top hair are still dark.I was thinking of dying my hair a light Brown to Auburn color or possibly a nice red color. Need advice on whether using a regular hair dye boxes or going to Sallys and getting color and developer there but Im confused on whether what strength of developer I should use or if I should add anything else. Please advice me on achiving perfect results with detailed instructions and materials needed will be well appreciated. Let me remind you my hair had been previously dyed black and now brown top blonde bottom in the past 2 years. Would like results that won't fade on bleached hair thank you.
