I have been dying my hair for four years but between each dying (semi-permanent) I let my natural color come back. The last few times I have done it have been at a salon, my hair dresser since I was three years old just retired and I had a new person dye my hair, he died it way to dark and it has not been coming out properly. What can I do to get my natural hair color back after a botched semi-permanent dye job?;)
