Hi a month ago I used a color remover color oops and it took out all of the auburn brown I had in my hair. Yesterday I did a bleach shampoo to lighten my hair and it is now light brown. I want to color my hair to even out the color and cover my roots that are now 3 inches and dark brown. I don't know what color to use I was told since I bleached my hair and it is now porous i should use a dark blonde. I want to use a light ash brown would this be okay on my hair and my roots I don't want uneven color.

You will have to treat the newgrowth with a different tint than the ends. The new growth needs to be lifted to the light brown. (20 or 30 volume developer) The ends need to be toned.( 10 or less volume developer)
