I generally keep it at bay by keeping the side as short as possible at all times
What I know is the opposite way to prevent ingrowing, the sides should not be cut short, growing them as long as possible lined straight. I also didn't know this until I rigorously watched instructions on Youtube.

Probably wise (depending on where you're from).
I'm from Korea and yeah I'm kinda proud you had the surgery done in Korea. These are one of the facts that Korean medical systems are the best in the world. And I can't give up on having benefited from that.

and we'll be coming to them (as many already are like myself)
Well best of lucks with your journey ahead in your home country. Obviously it will be different from an international student's, as most likely you'll be welcomed by family and friends.
