From the picture, it looks like there is hair loss in my opinion, but it is happening all around your scalp in a diffuse
pattern.
Your hair is thick, so it is not easily noticeable. The only reason I say that is from the enlarged picture.
There are other causes of hair loss, such as thyroid, and other issues. You really should get it checked by a professional.
I think you have diffuse balding from androgen alopecia, because the density does not appear to be uniform in the
picture.
The truth is I don't understand sh*t about baldness, despite the fact that I visit these sites often. I guess I just feel I do, but the truth is
I'm not a dermatologist and I can only give my opinion.
That said, I had a friend whose older brother had alopecia from his immunity system. He temporarily lost his hair, including his eyebrows/eyelashes, but it grew back.
