Les parties de fixation comportent une pluralité de poils (20, 21, 22, 41, 41β, 42, 52) s'étendant à partir des surfaces des parties de fixation (40, 50, 80). Les centres de sections transversales des poils à la surface des parties de fixation sont disposés géométriquement sur la première surface. L'agencement géométrique est le long d'une partie d'une spirale sur la première surface. Au moins deux des poils de la pluralité de poils sont des premiers poils qui sont composés d'un conducteur de chaleur qui conduit de la chaleur vers les cheveux.
