Final answer:
The technique where fingers and shears glide along the edge of the hair to remove length is called slide cutting, which is different from razor cutting, texturizing, and point cutting.
Step-by-step explanation:
The method that involves cutting or layering the hair in such a way that the fingers and shears glide along the edge of the hair to remove length is known as slide cutting. In slide cutting, the hair is held between the fingers and the shears are slid along the edge of the hair, creating a soft and blended effect while removing length. This technique is often used to add texture and movement to the hair.
This technique allows for a very smooth transition between lengths, creating a tapered or feathered effect without any harsh lines. Slide cutting is often used to create movement in the hair and to blend layers seamlessly. In contrast, razor cutting employs a razor tool to achieve softness or texturization, texturizing reduces hair density and adds movement without altering the overall shape, and point cutting is used to soften the ends or add texture by cutting into the tips of the hair.
