Scalp Picking Hope?

Hello all, I am a 20 year old who has been picking my scalp for some time, but only recently did I realize the damage I was doing to myself. I have been nearly pick free since February but the hair on the top of my head is still largely missing. I have significant flaking in the areas I picked and can't really tell if it's diminishing. Anyone one out there have any stories of hope? Will my hair grow back? -M
