About a year ago I started getting some scalp problems, primarily an itch. I would scratch the itch so hard I would develop some raw areas on the scalp that would scab over. Yet I continued to scratch and pick at the scabs until I noticed patches of bald areas on the top of my head where I had been scratching and picking. Will these areas grow back hair in time? Have I damaged the roots to the point no hair will re-grow in these areas? It looks horrible. Thanks.
You are clearly developing traction alopecia and these areas may stay bald. This is an obsessive/compulsive disorder and you should see your family doctor about his/her recommendations for treatment.
