I trimmed off the fuzz on the back/sides a few days ago, as I usually do every few weeks. As for the rest of it, haven't cut it in at least 3, maybe 4 years now. I'm debating whether to let the undercut grow out and just leave it all long, or if I should just wait for it to get long enough and then re-cut the back/sides, because a period of time where I didn't have a mirror caused some accidents to happen and now the back is uneven/goes up too high for my liking. No one really notices but me, but that's enough. I guess if/when I give in and start letting the rest of my hair grow back in, I'll have plenty of time to decide whether or not I want to go back to an undercut after it's grown out. It'll be at least a year, which is why I haven't bothered to start the process yet. Hair is a pain in the butt.
