Calling all scalp scratchers

I'm wondering if any aggressive scalp scratchers can tell me if they've experienced hair loss. If so, does it grow back or was it permanent?

My story is this: My freshman year of high school, I was super stressed and began scratching my scalp in a rake like manner while studying. During this time I was diagnosed with seborrheic dermatitis. I don't know if the scalp scratching caused the SD or the other way around. I would often feel my scalp ooze after a scratching session, and would also have sebum under my nails. I don't think my scalp ever really bled. (As an example, I currently do not have SD and it would be difficult for me to scratch my scalp without it really hurting me.)

I *think* (but I am unsure) that I lost clumps of hair during this period. The scratching was very bad for a year and basically continued off and on for another 5 or 6 years. Sometimes it was more rubbing than scratching.

At some point in my junior year of high school (so 3 years after this began) I caught a glimpse of the top of my wet head and realized that my hair was thin. I attributed the hair thinning to scratching.

I'm now in my 30s. I think my hair is basically the same as it was when I saw it in that mirror. However, I have now been to 2 dermatologists that have diagnosed me with female androgenetic alopecia. Now I'm confused. Did I just have a hair loss disorder all along and the scalp scratching didn't affect anything or are the doctors wrong and my hair loss was a result of constant scratching? (I don't think it's impossible that they might be wrong since "scalp scratching" doesn't exactly seem extensively studied.)

Anyway, if anyone has any kind of similar scratching/rubbing experience and can tell me "yes I lost hair" or "no, I didn't" it would be super helpful for me.

Thanks in advance
