Rob i might be wrong, but here is one possibility. I went to a stylist that was recommended on this forum numerous times. They also used a razor to cut the unit in. They didnt even cut it in that short, and the hairs were all spiking up weirdly all over the place. The person blamed the unit and the hair ventilation. But then when i went home after a day the hair started to settle and i finished the cut in myself with a wahl clipper and it was fine and not sticking up weirdly. Perhaps its the razor? the razor seemed to make the hairs stick out into spikey and unruly for some reason. Id ont know why exactly. but it seemed to be the case for me. Especially when u cut it short
