I use to dye my hair a medium brown. After awhile I decided to get a perm. It lightened the hair on top of my head. I used a medium brown demi dye to make it closer to my natural but after a second perm its very light in yop of my head. The demi medium brown no longer does anything to the top of my hair. I then used a dark brown demi. That did nothing either. My hair is very healthy and I am taking very good care for it. Its conditioned often. Do I have to change back to a permanent hair dye? I didnt want to do that. Trying to do the healthier way.
