Abstract
Method and apparatus are disclosed for the optimal hair shaping treatment of hair coiled onto rollers, e.g. human hair, whereby the deformations of a roller body resulting during a hair shaping treatment are detected and introduced as deformation measurement values to an arrangement for developing the measured values, which compares at least one pre-determined characteristic measurement value corresponding to an optimal running of the treatment with the measured values and then indicates a concordance.
