The recommended hair cutting angle for long layers is a 90-degree angle. This technique involves cutting the hair straight up from the head, which allows for the creation of long layers while maintaining the overall length. By holding the hair at a 90-degree angle from the scalp, the stylist ensures that the layers are evenly distributed and blend seamlessly with the rest of the hair. This angle promotes movement and a natural look, which are essential characteristics of hairstyles featuring long layers.

Using a different angle, such as 45 or 30 degrees, would typically create shorter layers or a more graduated look rather than maintaining the length associated with long layers. While a 60-degree angle could potentially offer some layering, it does not provide the same fullness and softness that a 90-degree cut would achieve for this particular style. Thus, the 90-degree angle is the most effective for achieving the desired outcome in long layered hairstyles.
