What technique is commonly used for layering hair?

Point cutting is a technique commonly used for layering hair, as it effectively creates texture and movement by softening the edges of a haircut. This method involves using the tips of the scissors to cut into the ends of the hair, which can help to reduce bulk and add dimension without altering the overall length significantly. Point cutting allows for more versatility in styling, as it creates a more natural, blended appearance in layers compared to other techniques.

In contrast, slide cutting is often used to remove bulk and create a gradual transition between lengths but is not primarily focused on layering. Thinning typically refers to reducing the density of the hair and can be used in conjunction with layering but is not a layering technique itself. Blunt cutting involves cutting hair straight across the ends, providing a more defined edge and is not associated with layering, which relies on varying lengths to create depth and volume.
