Final answer:
A locking tool is used during the process of applying hair extensions to precisely section and hold the client's hair without causing any disturbance to the surrounding hair.
Step-by-step explanation:
A locking tool is a flat leather pad with fine teeth used to sandwich human hair extensions so that a specific amount of hair can be extracted without loosening or disturbing the rest of the hair during the process of braiding. This tool is essential for stylists who work with hair extensions, as it allows for precise sectioning of hair and avoids tangling or pulling on the hair unnecessarily.
When applying hair extensions, a stylist would use the locking tool to grip and isolate a small section of the client's natural hair. The extensions are then attached to the selected strands of natural hair, either through braiding, bonding, or another method of attachment. The use of a locking tool helps ensure that the extensions are evenly distributed and secure, which contributes to a more natural and professional result.
