Patches of my hairline burnt during a full face session Is there a chance that the hairs might grow back and burns will go away?

I believe patches of my hairline were burnt during a full face session. The hairs were not shaven down like they were supposed to be so I'm wondering how damaged my skin is? I also feel a shooting pain in one of the patches as well and it has lasted throughout the day. Another piece was burnt in the middle of my hairline and it looks like I might end up having a bald spot, I was wondering if there's a chance that the hairs might grow back and burns will go away?
