What is the difference between long layers and short layers?
First, the layer is defined by the height of the coating, not the length. The gap between the most extended end and the shorter layer is about 1-2 inches. The texture and density of the hair play an important role in deciding what level to get.
For example, if you have thick hair, you will be more suitable for long-layered hair, while short-layered hair is suitable for fine hair.
