I just had blood work done to test Thyroid function, total and free Tess levels, DHT levels and cortisol. All came back normal.
I'm sure I had TE after some events that took place almost 5 years ago. Lost majority of my hair 3-4 months after the event.
Till this day I lose about 200-300 hairs a day. Rogaine hasn't helped one bit after 11 months of continued use. If I rub my head long enough, I'll lose 1,000 hairs. It just won't stop falling out.
There is zero history of MPB on either side of family. In fact, I have uncles between 50's - 70's with full heads of hair, dad had a full head of hair till 60's.
What do you all think can be causing this?
Thanks!
