The present disclosure relates to a ready-to-use composition for permanently shaping keratin fibers comprising, as permanent shaping agent, at least one tetramethylguanidine, a kit comprising compartments comprising the contents of the ready-to-use composition, and also to a process for using this composition. The wiping plate includes an essentially plate-shaped support plate with an elastically resilient foam member that can be fixed to the bottom face thereof. The formation of the magnetic field promotes ion extraction, but this magnetic field has no influence on an advancing direction of the extracted ions. The first control signal is applied to the phase and gain adjuster to control the gain of the phase and gain adjuster. Preferably, the resources are dynamically determined by observation of their interactions, such as observing the participation of nodes and links in message flows.
