Abstract

La présente invention concerne la fixation des postiches (401) sur la tête. L'invention concerne plus particulièrement un nouveau type de postiches (401), ainsi qu'un mode de collage de la postiche (401) à même la peau au moyen d'un adhésif, c'est-à-dire un adhésif dermatologique ou de contact. Cet adhésif peut être directement ou indirectement en contact avec la postiche (401). Lorsque l'adhésif est directement en contact avec le postiche (401), l'une des faces de l'adhésif contient en plus une couche thermofusible (404) servant à fixer l'adhésif sur le postiche (401). Selon encore un autre mode de réalisation, l'adhésif, avec ou sans thermofusible (404) peut être protégé par une garniture décollable (206), soit pendant la fixation de l'adhésif sur le postiche (401), soit préalablement à l'utilisation de l'adhésif. Selon un autre mode de réalisation enfin, l'adhésif se présente sous forme d'au moins une bande adhésive (400) servant à fixer le postiche (401) sur le cuir chevelu de l'utilisateur. L'invention concerne également un adhésif qui conserve toutes ses propriétés pendant une longue durée.
