Professional hair cutting shears require regular maintenance and sharpening to perform at their optimal level. Ideally, you should have them sharpened every 700 cuts or so. If you do more than 10 cuts per day, you're looking at getting them sharpened every two months. To extend the life of your shears, you should also take care not to use them in such a way that you will make them dull faster.
