Types of haircuts and short hair Haircuts and haircuts can be divided into different types based on the angle of hair cutting and cutting, each of which must be performed according to certain principles and steps. In order to cut the hair in the bob model or the models with straight ends, a zero degree angle must be used. In order to make the hairstyle triangular, a 45-degree angle is used, and to give a layered shape to the hair in short, a 90-degree angle will be set. Also, if we want to arrange and dress straight hair, we will consider a short hair angle of 180 degrees.
