The purpose of this article is to better understand, through the study of this micro-dynasty’s trajectory, the elements that structured the Parisian haute coiffure market in the middle of the 19th century. Hair implantation devices or dyeing brushes, the products patented by the Croisats were intimately integrated with the process of designing hairstyles on the one hand and their commercial strategy on the other hand. Their intense pedagogical activity, both in the newspapers and their academy, responded in an original way to the contradictions between the artist’s need for visibility and the defense of the patentee’s requirement for secrecy. Through the dissemination of models and crafts, the entrepreneur-innovator thus participates in the construction of a market for the products they imagine.}}
