Scissors come in different sizes. And the sizes between 5” and 7” are most ideal for modern hairstyling, shaping, and cutting methods. But the truth is that comfortability and use will determine your ideal size. Most male barbers prefer longer scissors (6” – 7” long). While female hairstylists find 5” to 6” scissors most ideal. And don’t forget, your hand size will weigh in on this too.
