I am in a panic as maybe I have DUPA?

I’m 18 and I’ve had diffuse thinning for the past 3 years. Yes it sucks but it’s slow and still have decent amount of hair. I’ve noticed for the past 3 years that when ever I get a hair cut, my hair is easy to pull out. Same with sides and my back. Is this DUPA? I’m really worried because I hope it isn’t. I took pictures with the flash and it’s still thick. Also when my sides grow out, I try pulling on it and it doesn’t come our. WTF.

I am the doctor who defined DUPA and it is rare. You need to have a microscopic examination of your donor area if you want DUPA eliminated as a diagnostic possibility. Most hair transplanted doctors offer this.
