The process for permanent shaping of hair including the steps of treating the hair with a hair shaping agent, bringing the hair into a desired shape before and/or after treating the hair with the shaping agent, rinsing with water as needed, subjecting the hair to an oxidative aftertreatment, setting the hair to form a permanent wave and drying. To provide a permanent shaping which does not leave the hair with an unpleasant odor and is safe for the hair, the hair shaping agent consists essentially of an aqueous composition containing from 0.1 to 30% by weight of at least one Bunte-salt and from 0.5 to 30% by weight of at least one sulfite or hydrogen sulfite. The sulfites and hydrogen sulfites are selected from the group consisting of alkali metal and ammonium sulfites and hydrogen sulfites and alkanolamine salts of sulfurous acid. The Bunte-salts include various thiosulfate-containing compounds.

Method for permanently shaping hair

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.
