Abstract

Selon l'invention, la perte de cheveux est inhibée et occasionnellement un ralentissement de la calvitie ou une amélioration au niveau des cheveux fins (restauration capillaire) est obtenue, par diminution de la tension au niveau du cuir chevelu au sommet de la tête. La périphérie d'une partie tête du corps humain est comprimée avec une distribution de pression de contact inclinée par un élément de presse en forme de ceinture incurvé latéralement, de façon que la circulation sanguine vers le cuir chevelu du sommet de la tête est assurée par l'utilisation de la pression sanguine systolique produite par le coeur de l'utilisateur. En conséquence, pendant le port du dispositif auxiliaire de croissance capillaire, on peut inhiber la chute du cuir chevelu du sommet de la tête dans un état de stase, et la tension du cuir chevelu peut être confortablement réduite avec une force de serrage accrue.
