Is this an infected cut or scalp psoriasis? (Photo)
I've had this for about 2 years now. I believe it came from a cut I received back then from my then barber who used a razor blade while cutting my hair the cut was not very big. It has a white scab/dry skin that builds up on it and I do occasionally pick at it since it's very frustrating. It does not hurt unless I peel off all the scab and then it'll bleed a little bit in some parts. Please any help is appreciated!!
