Abstract

Dans différents modes de réalisation illustratifs, l'invention concerne un procédé de conseil en traitement capillaire assisté par ordinateur. Ce procédé peut comprendre les étapes consistant à enregistrer au moins trois images numériques des cheveux d'un utilisateur au moyen d'un appareil photo, à former un modèle 3D d'une coiffure des cheveux pris en photo, à déterminer un volume de zone capillaire, dans lequel les cheveux sont représentés, dans le modèle 3D, à déterminer une nouvelle couleur de cheveux et/ou une nouvelle coiffure, et à afficher le volume de zone capillaire en tant que volume de zone capillaire traité dans la nouvelle couleur et/ou avec la nouvelle coiffure.
