Abstract: The adjustable mannequin head is configured with a postiche. The postiche mounts on the adjustable mannequin head. The adjustable mannequin head comprises a cranial structure further comprising independently adjustable sections that correspond to the cranial bones of a human skull. The independently adjustable sections adjust such that the exterior surfaces of the adjustable mannequin head can be adjusted to resemble the shape of the head of a client. The adjustable mannequin head comprises the cranial structure, a plurality of bolts, an anchor structure, and an orientation structure. The cranial structure supports the postiche during the hairdressing activities. The plurality of bolts adjusts the shape of the exterior surfaces of the cranial structure. The anchor structure secures the plurality of bolts into position. The orientation structure provides a hairdresser with cues that allow the hairdresser to envision better how the postiche will look.
