Answer:1. 0 Degrees (Blunt Cut): Hair is cut straight across without elevation, resulting in a solid, blunt look. This is often used for bob cuts.2. 45 Degrees (Graduated Cut): This elevation creates a layered effect, adding volume and shape. It’s commonly used for bobs and layered hairstyles.3. 90 Degrees (Uniform Layer Cut): Cutting at this angle creates layers that are even throughout the hair, adding movement and texture.4. Over 90 Degrees: This is used for very layered styles, where the stylist lifts the hair higher to create extreme layering and texture.
