Teaching aid for hair cutting

The utility model relates to a teaching aid for hair cutting, particularly a teaching aid for hair cutting that a face contour, a tectum and hairs can be assembled. The utility model comprises the hairs, the tectum and the face contour, wherein the tectum is butted with the face contour into a whole. The butting part is provided with the same contour cross section. A piece of soft rubber skin is planted with the hairs, and is arranged on the tectum. The hairs of the utility model can be taken off the tectum. When the first teaching mission is accomplished, another fistful of hairs can be exchanged and thus the whole teaching aid for hair cutting is not discarded.
