Abstract: A re-useable haircutting collar that is water resistant to dripping liquids and hair particles to protect a user's clothing and skin. The collar is made from flexible silicone or latex of a shore rating of extra soft to soft, skin adherent, non-toxic, and is a ring-shaped sheet, with an inner edge, mid-section, and outer edge, and with two opposing ends that overlap. The ends are tightly self-adhering to each other; therefore, the collars do not require fasteners to secure the ends together, and can be easily adjusted to fit any neck size to form a tight, but comfortable water seal. The collar is also lightweight and bendable to lay about vertically against the base of a user's neck and angled along their collarbone. Different collars embodiments also comprise differences in the thickness along the collar width at the top surface to provide different levels of collar flexibility.
