I just turned 17 and I can grow sideburns relatively fast, but for some reason my left sideburn always seems to grow faster than my right, which is weird. Its not insanely noticeable unless you compare the two, but I'm wondering how I should go about evening them out? Should I shave my left sideburn and not my right one over the weekend and let my left one fill out or should I shave my right sideburn (knowing that the more you shave it the faster it grows back) over the weekend and hope it catches up with my left?
