I've been headblading for a little over a year and a half now, and still give myself the occasional nick/cut. Best bet to avoid a nasty looking mark, is to get one of those styptic pens they sell in the shaving isles. They stop the bleeding right away ( a little sting here and there, but bearable). I always have one standing by, plus a little neosporin as well to prevent scarring. Usually, if and when I do slip and slice, I jump on it right way, and the results are pretty good. Healing time depends on the depth of the cut...if it's bad, it can take about 4-5 days to heal. My advice is to all headbladers is to go slow, and do NOT apply pressure to the blade. Good luck, and keep it sly!
