How Often Should Scissors Be Sharpened?

Many hairstylists often ask how often they should get their scissors sharpened as they know if they wait until the scissors do not cut as well then it is already well past time to get it done. The best hair scissors according to many top makers of professional shears will last for approximately 700 haircuts or roughly 90 days for the average user. Of course this number can be higher or lower and there is no absolute easy way to tell but for many stylists this rule of thumb works out fairly well to keep those scissors cutting their best.
