What is the appropriate angle for holding shears during a haircut for layering?

Holding shears at a 45-degree angle during a haircut for layering is appropriate because this angle allows for effective control over the length and texture of the hair. When styling for layers, a 45-degree angle promotes the creation of soft, blended layers rather than blunt cuts, resulting in a more natural look. This angle helps in removing weight from the hair while allowing for movement and volume, creating a visually appealing layered effect.

While other angles, such as 30 degrees or 60 degrees, might be used in specific contexts or for different styles of cutting, they do not offer the same balance of elevation and technique needed to achieve effective layering. A 90-degree angle, on the other hand, typically results in a uniform length and can lead to a more geometric or structured cut rather than the softer, more textured appearance characteristic of layered hairstyles. Therefore, the 45-degree angle is the most appropriate choice for achieving the desired layering effect in haircuts.
