The highest priority at L’ANZA is the safety and welfare of our customers. L’ANZA uses only the safest and highest-quality ingredients in all products. L’ANZA formulas meet rigorous safety standards and are sold in 40 countries around the world. L’ANZA ingredients have been thoroughly tested in salons and proven to be safe for use.


L’ANZA was introduced to the beauty industry as one of the first professional haircare brands specifically designed to address individual hair needs. Using the proprietary Keratin Bond System, L’ANZA is able to target the causes of hair damage, not just the symptoms. L’ANZA built upon this tradition of keratin, incorporating the latest in haircare ingredient technology, as well as wildcrafted and sustainable plant-based ingredients, creating the Keratin Healing System (KHS). With the power of Keratin Amino Acids, Healing Actives, Protective UV Ingredients, Nano Science 10² delivery system, sulfate-free and sodium chloride-free Shampoos, KHS has become the foundation for all L’ANZA products.


UV sun rays have long been recognized as damaging to the skin. But ultraviolet rays are also damaging to hair and a leading contributor to hair color fading. L’ANZA utilizes full-spectrum UV protectors to guard hair color against damaging UV rays, ensuring maximum protection from fading.


L’ANZA’s exclusive healing formulas are not only color-safe, they also help to maintain hair color longer by healing damaged fibers. Hair that is damaged is porous, allowing color pigments to escape outward from inside the hair fiber. When hair is properly healed and sealed, color pigments remain contained within the fiber to provide longer-lasting hair color.



L’ANZA products provide an extra measure of thermal protection. Our exclusive healing formulas protect hair from the most intense heat. Healing action seals the hair to provide an effective shield from thermal trauma. Heat is less likely to penetrate deep into the hair cortex of a healed hair fiber to cause structural damage.



Humidity is atmospheric moisture comprising of fine particles of water droplets suspended in the air. The problem with humidity is that it causes frizz. Even slightly porous hair absorbs atmospheric moisture, much like a sponge absorbing water. When this happens, the hair fibers swell and enlarge, the cuticles are pushed outward and the result is unwanted frizz.

The key to preventing frizz is to reduce porosity and seal out atmospheric moisture. That’s exactly what L’ANZA products do. The Keratin Healing System heals the hair and seals it, protecting hair from humidity intrusion and unwanted frizz. Because of this healing activity, all L’ANZA products provide utmost frizz protection.


As technology has advanced, scientists have discovered new ways to make ingredients smaller – so small they have to be measured in nanometers. The result is outstanding softness and silkiness with exceptional body, even for the finest hair stands.


All shampoos contain surfactants, which supply cleansing action and lathering properties. “Surfactant” is an abbreviation for “surface-active agents” because they help break the surface tension of water, allowing it to better remove oils and debris from the hair. Surfactants are divided into two types: Sulfate and Sulfate-Free.

L’ANZA technology has allowed us to develop blends of non-sulfate surfactants that provide a rich lather in our sulfate-free shampoos. There are also surfactants that are not sulfate-based, but just as effective at gently cleansing the hair. These sulfate-free blends are milder and have been proven to extend the life of hair color.



Gugo Bark has been used by native Polynesians for centuries as a natural surfactant to gently refresh and purify hair. The bark’s extract produces abundant lather that lifts away impurities without removing vital oils or nutrients from the hair. To provide gentle cleansing and abundant lather, L’ANZA uses Gugo Bark in all Advanced Healing Shampoos.



Sodium Chloride, also known as salt, has long been used in shampoos as a thickening agent. However, many smoothing systems recommend their clients not use shampoos that contain Sodium Chloride because it can interfere with the chemicals that smooth the hair. For this reason, L’ANZA has formulated our Advanced Healing Shampoos without Sodium Chloride. Our shampoos are safe and effective to use with smoothing systems.



All L’ANZA Advanced Healing products use Paraben-Free ingredients to protect against a broad range of microorganisms. Additionally, all L’ANZA products are Gluten Free.
