Does anyone have diy scalp treatments for picking?

I'm an 18 year old girl and I have struggling with picking at my head every day for 3 or 4 years now. It all started when I took adhd medication but I'm obsessive compulsive as well and haven't been able to kick the habit. I have bald spots on my head and sores everywhere. It hurts and it's depressing to be a young female and have thinning hair because of a compulsion. I was wondering if anyone had treatments to soothe and maybe help get rid of sores? I'm getting black soap shampoo but for now I'm hoping for something I can find or make around the house. I've struggled with impulses and addiction to substances and things all my life but this is just one of the habits that is so hard to kick and it's so depressing. The picking has gotten so bad that it's spread to my face. I never break out but I pick at my face now too and I just want to try to quit already but it's so hard.
