I'm wearing a man bun/top knot, sides and top are long but I want to cut the sides.
Which option is best? I was thinking about it being an iterative process -start with a straight line like 2 just shorter.
I see a lot of people rocking curves like 3 but personally don't like it at all. Anyone with some experience who can weigh in and recommend the optimal height, orientation and curvature? I got these little 'spikes' on my hairline and my idea was to get a cut like 1 starting from the middle of those peaks.
