Abstract: A teaching and training head model for haircutting and hairdressing includes a soft and flexible synthetic resin casing, a shape keeping arrangement mounted in the casing to keep the shape of the casing and a support stand for supporting the shape keeping arrangement. The support stand includes: a base board; and a guiding bar, a pushing cylinder for lifting plates and a pressing cylinder which are centered about the center of the base board and sequentially positioned on the base board from inside to outside. A fixing ring for fixing the casing is provided at the periphery of the pressing cylinder. The shape keeping arrangement includes components fitted with the support stand and umbrella-shaped supporting components for supporting the casing. The shape keeping arrangement has a simple structure, and it will expand to keep the shape of the casing when the shape keeping arrangement mounted in the casing is inserted into the supporting stand. The shape keeping arrangement is simple to assemble.
