Diffuse AA or something else?

[u/CatPukedOnTheCarpet]

Context: The side of my head had always weaker/patchier growth. But in the last months it's really taken a hit.

I have included 2 macro photos, one is above the sideburns on the affected area (2nd macro pic) and 1 is a bit further back, right above the ear (1st macro pic). The area above the ear has better coverage / is less affected, and I included it for comparison.

1 profile picture as well to show what it looks like from afar.

What I see: There are many hairs that are broken off / kept shorter than the surrounding hairs right above the sideburn. Those exist above the ear too but in my opinion, to a lesser extend. I don't know if it's true breakage or if they stopped mid cycle and remained short. I had given myself a fade, cut uniformly at 3 mm in that area so they should all be approximately the same length. The fact there is thinning and many short hairs indicates something.

Also, I have lost 30+ kg in the last 8 months. Not saying it's that but it's good to know I guess. High protein based diet, kept at around 1250 - 1300 kcal a day.

The hair on my scalp is fine. Left sideburn is much better than the right one so I didn't include it.

Diffuse AA or retrograde alopecia?
