I would say their hair has grown, but it's very thin and straggly as long hair on biological males often is, so E2 is wearing clip in extra rows around the top of the head. The front is probably the real hair which explains why E2 is constantly fiddling with it. And if it's clip ins, they might be worried about the tracks showing or them falling out if they style it.If you zoom in, there's a really obvious line across the top of his head, going almost ear to ear as well... very odd. Don't know why they don't put it in a ponytail or plaits so they don't have to keep pushing it out of their face.
