Long Layers or Short Layers
A: One hairstyle can have many different lengths of layers. The potential length of layers is determined by how long the hair is before the hair is cut. Thus, a long hairstyle can have a combination of long and short layers, whereas short hair is limited to short layers, because of the physical short length of the hair.
This being said, the hairdresser will most likely ask you to show him/her an example of which kind of long layers you have in mind, as “long layers” is a very broad type of hairstyle, and misunderstanding can easily result between the client and stylist.
“Emo,” “scene” or “rocker” hairstyles often have a combination of very long and very short hair. In these cases, the hair on the crown area and bangs may be quite short, while the tips of the hair may hang to the middle of the back. These long and short layers are often disconnected and thinned out/razored for maximum movement and texture.
