Has My Hairline Matured Or Am I (slowly) Balding? 23 Y/o

[grexx]

Hi, I‘m almost 23 years old and wondering whether my hairline has matured or if it is receding. I‘ve had a high hairline since my childhood and it has moved a little further up like 4 years ago. Would you please help/advice me?

For me you already had signs of hair loss in 2016 - the temples seemed fine but the hair line in the center seemed receeded to me alredy back in 2016- but maybe that was just your specific hair line

Got a picture from 2012, 2013 or 2014?
