question: Hi doctor, I shave my head with a razor blade once in a few days as if shaving my face. I have been doing this for seven years now. Four years ago, my doctor noticed that I had a discoloration on the back of my scalp. He said it was nothing to worry about and had probably always been there like a birthmark. Now, a few years later, it has never actually gone away. It has become bigger, more pronounced and red all the time. It does not itch ever, but it does stay red and feels rougher than the normal skin to touch. It just looks like a bright red rash that never goes away. It does not turn scaly or white and also does not flake off to my knowledge. I do not have a lot of anxiety over it, but it is extremely embarrassing to the point where I do not show my full head a lot in the public. Could it be folliculitis? Could that last for years? Please help.
