@Krrygon Insert 'here's the fun part - you don't!' meme here.
But honestly, tying it back in a ponytail if it's going to be a serious issue, trying to tuck the loose parts behind my ears, or wearing a hoodie with the hood pulled up and hair tucked in there a bit.
Alternately, just learning to accept that my diet is going to be partly my own hair (and partly my cats').
