Pressure-Sensitive Hair Grooming Device

Abstract

A novel device for hair grooming comprises a flexible guide band and a pressure sensitive adhesive (PSA). The backside of the guide band may include a coating that prevents adhesion with the PSA to allow the device to be rolled up without the need for a liner. The device is configured to reversibly adhere to the hair and skin of a user to act as a guide for hair trimming or grooming. The device can be applied, removed, and reapplied without discomfort or damage to the skin or hair. The guide band is preferably made of silicone rubber and the PSA is preferably a pressure sensitive silicone or acrylic gel. The device may take on a variety of shapes and patterns. In one embodiment, an intermediary bonding layer positioned between the guide band and the PSA allows for the use of a broader range of guide band materials.
