I used to have tons of hair, huge volume on top. Now I still have lots of hair sides and back but the top and front is and has gradually become flat and thin. I am desperate. I lost a chunk of front center hair about 14 years ago and could never figure out why or what, then dx'd with hashimotos a couple years later which didn't help. Now over time, the volume got less and less. Now I just read that there is something called frontal alpecia or FAA that is auto immune related and the hair never grows back. I have eyebrows still, my loss is the front and temple areas, and now I see it in my side part and flat on top, am definitely losing losing losing my hair. How do I know if it is this? Does anyone know anything about this to help me??????
