I have a problem that I have been worrying about for quite sometime. About a year ago while I was driving, I brushed my hand through my scalp and noticed that I had time hard little brittle hairs almost like after you get a buzz cut, on my scalp. I had hair that was almost 2-3 inches long at the time so it didn't really make sense to me. I brushed it off and didn't really pay attention to it that much. A few weeks later, I got a haircut and asked my barber to time my hair with thinning shears. She thinned it out a little too much and it looked like I had severely thinning hair under a bright light. Fast forward to now, it's been almost One year so since my hair cut. My hair still looks pretty thin. Also, there are still brittle hard little hairs on my scalp whenever I put my hands through it. It seems like I still have tiny buzz cut length hair where it is thinning but it just doesn't grow back. I am confused and I can't really find out anything about it.
