System Professional LipidCode™ Complex is a patented smart technology enriched with hair identical lipids that penetrate deep into the core to regenerate your hair and restore lost lipids. When the hair loses its natural lipids (when brushing, styling and washing), it becomes increasingly vulnerable, weak, dull and rough. Our LipidCode™ Complex can be found in a number of our products with the goal of making the hair softer, shinier and more resistant against breakage. You can also discover your personal LipidCode by taking our hair quiz.
