Understanding the root cause of frizz with protein science

Our protein science experts identified the root cause of frizz as damage to the outer cuticle protein layer. Heat styling and environmental factors can crack the cuticle, allowing moisture to swell the hair fiber and create frizz. Healthier, intact cuticles result in softer, smoother hair that is easier to manage and style.

ProteinFusion™ blend ingredients, including almond protein and Jasmine Flower, is shown in glass dishes.

Our exclusive ProteinFusion blend

Our innovative ProteinFusion™ Blend is custom-crafted for frizzy hair. It contains almond protein, with moisture-repelling amino acids to block humidity and frizz. It also includes jasmine flower, known for its ultra-light moisturizing properties that nourish the cuticle and help prevent damage.

Our system restores strength from within by filling holes and cracks in the outer cuticle. An invisible, hydrophobic (water-repellent) barrier then weightlessly wraps each strand to provide frizz protection in up to 98% humidity.
