Do I have diffuse hair loss? If yes, can I not do a hair transplant? (photos)

My hair started thinning in 2016 (not genetic). Started minoxidil 5% (not finasteride, for reasons), without much success. Had 2 PRP sessions in 2018, and the second time the doctor told me that the hair density has increased a bit. Two doctors refused to do hair transplant, as I don't have certain distance between 2 hairs in a specific area on my scalp. So my questions are: 1)do I've diffuse hair loss? 2)If yes, is there no chance I can do a transplant in the thinnning areas? Thanks!!!
