What technique is used to blend hair lengths?

The technique used to blend hair lengths is fading. Fading involves gradually shortening the hair from the top down to the sides and back, creating a seamless transition between varying lengths. This technique is commonly employed in barbershops to achieve a clean look that gradually blends different lengths, particularly in men's haircuts. Fading not only provides a polished appearance but also enhances the overall shape of the haircut.

Layering refers to cutting hair at different lengths to create movement and volume but does not focus specifically on blending lengths in the same way that fading does. Texturizing is a technique used to alter the surface of the hair to create more texture and remove bulk, while thinning is aimed at reducing the volume of thick hair. Both texturizing and thinning can contribute to a finished look but are not primarily about blending hair lengths.
