The professional scissors from KYONE are ‘conditioned’. This process is many times more refined than the ordinary sharpening of hairdressing scissors. Some scissors are more than 12 years old! How is this possible? Through good and regular maintenance! This is of course a fairly broad concept and that is why we are happy to explain when it is necessary to have your scissors conditioned in the Kyone Service Center. We recommend having your scissors conditioned every year and a half to maintain and guarantee a perfect cutting quality. As soon as you notice that your scissors don't cut properly or when you have to put more force than normal, your scissors are probably damaged. We advise you not to continue cutting with the scissors, but to have your scissors conditioned in our Kyone Service Center. Our specialists ensure you that your scissors will cut like new after that! If you want to have your scissors conditioned in our Kyone Service Center, we advise you to send it back to the wholesaler where you bought it. They will then ensure that it ends up in the Kyone Service Center.
