Visit the L'anza website here Tortuga carries the entire L'anza collection. L’ANZA was introduced to the professional Haircare industry in 1985. It was the first major brand of Haircare to address individual hair needs through collections of formulas designed to treat hair and achieve therapeutic results. The proprietary formulations were designed around a revolutionary breakthrough – the Keratin Bond System (KBS). This protein delivery system uses an exact ratio of hydrolyzed keratin amino acids from human hair, vital minerals and herbal extracts, giving the hair unprecedented luster and manageability. With Keratin Bond technology, the inner structure of the hair was dramatically strengthened to make it look and feel stronger, softer, and remarkably healthy. L’ANZA pioneered a whole new category of Healing Haircare. Hair is under constant attack from the environment and more people are chemically processing their hair. These new stress factors began affecting the hair. The hair needs to be strengthened and fortified to defend itself from the harsh aggressors it’s exposed to on a daily basis. L’ANZA therapeutic formulas target the causes of hair damage… not just the symptoms. The Keratin Bond System was enhanced, and emerged as the Keratin Bond System 2 (KB2). Using the same base of Keratin Amino Acids found in KBS, KB2 includes the Meadowfoam Flower Seed Complex and Moisture Retain Complex to work synergistically with KBS, adding extra moisture to the hair. The products containing KB2 can be now be found within the L’ANZA Healing Collection KB2. L’ANZA uses the latest technology available to deliver the strongest, healthiest hair. While many haircare lines claim they repair the hair, L’ANZA is the only brand able to heal the hair. Through the Keratin Healing System, Triple UV protection, Nano Science 10² delivery, sulfate-free and sodium chloride-free Shampoos, and the Flower Shield Complex, L’ANZA Heals, Seals and Protects all types of hair, delivering maximum shine and color that lasts!
