Secondly, honourable minister, though this haircut looks super low maintenance, regular trims are a must if you want to maintain this style. So provided there's room in the 2021 budget (haha), it's worth investing in a pair of quality clippers to use at home.
Be sure to clean your clippers thoroughly after each use to banish any bacteria which could cause scalp irritations or ingrown hairs. To do so, remove any stray hairs from the blades with a small brush before lightly sprinkling them with methylated spirits. Turn the clippers on for a few seconds to distribute the meths through the blades, then set them aside to dry.
