Abstract: Apparatus for trichotechnical and aesthetic hair treatments based on the use of a nebulized mixture of air, steam and ozone, which apparatus comprises suitable means for enabling the amount of each component of the mixture, as well as the mixture application temperature--with the latter being anyway designed to be controlled at values similar to, or lower than, user's body temperature--to be independently, either manually or automatically, controlled, securing the obtainment of optimal temperature values and distribution pattern of the treatment mixture inside a bell-shaped headpiece, as well as a controllable ozone production, thanks to the use of electric-brush discharge ozone generators (ozonizers), the magnetic field of which is completely dissipated without neutral conductive connection to earth by virtue of a specific shielding of the containers of the electric-brush generator bulbs with a brass net, with means being furthermore provided in order to feed the mixture into the headpiece, which means are s
