Head massage comprising a housing defining an internal chamber in which a skin aspect is formed when applied to the skin Patient Diseasewhere the aspect referred to is in contact with the lower limbs of the chamber,where this chamber is defined by two side walls (12, 13) and two transverse walls,At least one of the abovementioned transverse walls consists of a section (valve) 10 capable of moving with one rotating motion so as to cause the Approximation and dismantlingtightening of each lower edge (16) of these transverse walls when in contact with the skin aspect. The branch (10) is articulated close to the top of the side walls (12)13). The branch rotation (10) is achieved by means of a torque reducer fixed within the said branch whose output axiscauses rotation in a centre obtained within a centre track fixed to one of the side walls of the inner chamber.
