Abstract

Un dispositif de soins capillaires selon la présente invention comprend un boîtier qui présente un trajet de soufflage en son sein et constitue le profil externe du dispositif. Le boîtier comprend : un boîtier de décharge en colonne présentant, sur sa paroi périphérique, un orifice de décharge qui communique avec le trajet de soufflage; et un boîtier de préhension en colonne s'étendant dans une direction perpendiculaire à la ligne normale de l'orifice de décharge. De plus, la ligne centrale du boîtier de décharge et la ligne centrale du boîtier de préhension sont sensiblement les mêmes. Le but de la présente invention est d'obtenir un dispositif de soins capillaires capable de réduire davantage la charge sur un utilisateur.
