Abstract
A hair pulling apparatus includes a frame having a longitudinal axis, a first leg extending from the frame, a movable leg spaced apart from the first leg, the movable leg extending from the frame and movable, linearly, relative to the frame, a control system comprising a processor to execute a plurality of pulling profile instructions stored in memory, a linear actuator operatively coupled to the control system and constructed to move linearly along the longitudinal axis relative to the frame, a gripper coupled to the linear actuator, and a load cell coupled to the linear actuator. When one or more of the plurality of pulling profile instructions stored in memory are executed by the processor, the control system causes the linear actuator to retract along the longitudinal axis, applying a pulling force to a strand of hair gripped by the gripper in order to measure the pulling force.
