Sebastian is the inventor of the crimping iron, first semi-permanent, ammonia-free hair colour Cellophanes, first wet gel, as well as first combined hair care and styling Potion 9. Sebastian Professional was founded by LA stylist Geri Cusenza on the principle of fearlessness. A thirst for innovation and desire to change the game have always been Sebastian’s raison d’être. Sebastian inspires the artist inside every stylist with new techniques, providing new professional styling and hair care products for new-to-the-eye looks.
