I'm not sure if there are specific criteria for starting hair loss treatment.

It’s not like I’m suddenly losing a lot of hair, but it seems like the crown of my head is a little more visible than before.

When I take photos and compare them, I get confused whether my hair has really thinned out or if it's just because of the lighting.

I'm not sure if I should get tested at the hospital in this ambiguous state or if I should wait and see a little longer.
