Is this CTE or AGA? (Photos)

I suggest you see a cosmetic physician who specializes in hair loss to assess your situation and provide options.  Dr. Emer.

It is hard to know before you getting a microscopic hair evaluation. Microscopic hair analysis or miniaturization study tells us whether you have active hair hair loss or that you have lost some hair in past and the process has stopped. 

One can not diagnose AGA and CTE based on the information provided. You need a comprehensive examination with thorough review of your follicular densities, miniaturization patterns and scalp. You also need review of your blood tests.Spironolactone can cause shedding in the first 2-3 months fairly commonly.
