It consists of a body 1 with elastic tabs 2 equipped with discs 3 between which is mounted a rotary roller 6, which discs engage in recesses 7, allowing the oscillation of the head which has a ramp 12 oriented towards the opening of the reservoir containing the wax. The head may be separated from the opening of the container, so that it can be replaced by another one, preventing possible cross-contamination of micro- organisms between persons to whom the head is applied. <IMAGE>
