"The term 'invisible layers' refers to removing weight and adding movement into a haircut while creating a finished look with minimal or no layers at all," Omar Antonio, hairstylist and global top artist for Sebastian Professional, told POPSUGAR. That means subtly cutting layers within layers of longer hair for an infinitely more discreet — and therefore, natural-looking — effect.
The cut works across all hair types and textures, but if you have short hair, asking for "pen cutting" can give the style a little more shape. The key, he said, is to take the feather razor and hold it like a pen to add detail to layers. "Pen cutting puts your autograph on the hair."
