I’m 21 and already have crown loss (photo)

There may be a suggestion of hair loss in the crown, but what about elsewhere, hair loss that you can’t see. You can lose hair up to 50% and not see the loss, but then if you start treatment after the 50% loss, what you lost may be gone for good. Get on top of it, get a HAIRCHECK test (https://baldingblog.com/haircheck-test-how-it-is-done-video/) and if you have say 25% loss elsewhere, you can start treatment early with a good doctor who understands the idea of a Personalized Mater Plan for you as you age and lose more hair.
