hi. i’m only 16 and for a year my hairs been thinning and scalp showing. i usually grow it out very long then shave it. now its shaved and once in a while theres mini hairs no more than 5 millimeters long here and there. i was also on a lot of steroids like protopic and hydro-cortisone for my eczema.
You steroids could be responsible for thinning. You need to discuss this with your doctor. There’s not much more I can offer without knowing more of your history and examining your scalp.
