What is the recommended angle for using shears when cutting hair?

The recommended angle when using shears for cutting hair is significant because it influences the outcome of the haircut. A 45-degree angle is typically used for blunt cuts, which creates a clean, straight edge across the hair. This angle allows for maximum weight at the bottom of the hair, providing a strong and defined line.

For layered cuts, a 90-degree angle is used. This angle allows the stylist to remove weight while still maintaining a balanced shape and providing movement throughout the hair. It elevates the hair away from the head, which is essential for adding layers and texture, giving the overall style a more voluminous appearance.

Using either of these angles produces the desired results for the respective cut techniques. Other angles, such as those mentioned in the remaining options, are either less common or not suitable for the standard practices in haircutting that require precision and consistency.
