21m. Mature hairline or start of MPB?

I have no history of baldness in my family on either side, but I am starting to get concerned whether I have a mature hairline or the start of MPB. My hair is not shedding more than a normal person and it's completely normal in terms of shedding. When I run my hair through my hands I rarely see any hair come out.

I attached some pictures they are going in order starting with Feburary 28th till today, may 3rd. The starting picture (Feb. 28th) has the date on the picture

Bottom line: Should I think about going to a dermatologist to see if my hair has miniaturization or am I fine?

can someone please reply? this is not a joke whatsoever. Just need some opinions so know whether to see dermatologist

My scalp looks similar to yours, I am by no means a professional but my hairline seems to be a little further back than yours and most people so far told me that its fine. Maybe your hair is just fine rather than thin. Thats something iv'e been wondering about my hair. It looks fine imo.
