Because of how your selfie camera works! (Also, it's a 15 degree angle)

So here's the thing: your selfie camera is a short-focal-length scanner, not a true camera, and in effect has a fisheye effect on any images it takes. That'll make parts of your body look really weirdly disproportionate in subtle ways that make some parts of your body seem larger or smaller than they really are. Doing a 15 degree angle above your eye level makes that effect hit mostly on your
hair, where it's least apparent, and leaves your other body features in more realistic proportion.
