Is there a way that I can get my hair back?

I was born with pretty mixed hair and when I was 4 years old my grandmother mistaken perm for grease and she greased my hair with the perm and didnt wash it out. My mother ( who was very mad) she notice my hair droppin so she carried me to get my hair cut. And from tht day on she has been perming my hair and i am now 15. Is there a way that i can get my mixed hair back? my mother permed my hair so much that it changed color( not entirely) PS: I am black
