How can a stylist achieve uniform layers in a haircut?

Achieving uniform layers in a haircut requires cutting each section of hair at the same elevation. This technique ensures that all layers are consistently the same length, giving the hairstyle a balanced and harmonious appearance. When a stylist maintains the same elevation throughout the haircut, it allows for a seamless flow between the layers, preventing any unwanted gaps or unevenness.

Using varying elevations, on the other hand, would create a more textured or graduated look instead of uniform layers. Applying the same amount of pressure while cutting doesn't directly influence the uniformity of layers; it's more about the precision of the cuts made at the same elevation. Not using any tools would make it impossible to achieve any haircut with uniform layers, as the precision required to create layers relies on the use of cutting tools. Thus, maintaining consistent elevation is the key to achieving that desired uniform effect.
