Dozens of Ice pick scars on scalp from Acne?

Patient: Hi,I had acne on my scalp for about 6 years on and off and during that time i was pulling my hair through them due to depression and stress. Now i’m paying dearly for it, i have dozens of ice pick scars on my scalp and about 2 or 3 rolling box scar on my back scalp. It’s only noticable when i get a very short haircut. Im a male in my mid 20’s. Very embarassing.Is there any treatment that can fix this? Chemical peel on my scalp? laser treatment? I need a treatment where it won’t effecty my hair growth.
