Mature hairline or Mpb??

[WillAH]

Consulted a derm and he said I show no signs of mpb even though my temples seem to be going slightly thinner. Experienced Telogen Effluvium in the last year and seem to have recovered (I hope). Just wanted your honest thoughts, it would be greatly appreciated! If my hair goes eventually I'd happily wear a lace system, they look pretty good haha. I'm 21 aswell by the way, turn 22 this year.
