  • Patent number: 5252074
    Abstract: A magnetic three-dimensional analysis system for use as a tool in the demonstration of hairdressing techniques by an instructor and to aid a student in learning and practicing such techniques. In one form, the system includes four magnetic grid head forms: a left profile grid head form, a right profile grid head form, a front section grid head form, and back section grid head form. The grid head forms have flat backs which are magnetized so they can be attached to a magnetic blackboard or metal sheet. The system also includes numerous flat magnetic or adhesive strips with pointed ends. The strips are cut to certain lengths and color coded to represent different hairdressing techniques. In a preferred embodiment, a grid head form is attached to a magnetic board and the flat magnetic strips are then attached to the board around the grid head form to both define cutting lines and show proper hair length for a plurality of prescribed hair styles.
