Abstract

Moyen de peignage permettant un repérage de la charge électrostatique d'un ensemble de cheveux. Ce moyen de peignage, peigne ou brosse, comporte dans la zone de peignage un élément électriquement conducteur, qui est relié à un convertisseur tension/fréquence alimentant un compteur d'impulsions, ledit compteur fournissant une valeur numérique fonction de la charge électrostatique de l'ensemble de cheveux peignés. Utilisable pour effectuer des repérages comparatifs de la charge électrostatique conférée à une chevelure par un traitement cosmétique.
