The L'Anza hair care company claims their products are suited to the 80 percent of salon clients who have damaged hair. This damage stems from chemical and thermal processing and environmental toxins, which L'Anza aims to heal through nourishing, moisturizing and repairing ingredients. L'Anza has produced various dry hair shampoos, all of which have the following ingredients in common.
Jojoba
The wax harvested from jojoba tree seeds is a standard commodity in cosmetic products. Marketed as oil, this wax actually resembles sebum -- moisturizing skin oil that protects your body from infection -- and helps to balance pH in a similar fashion. Acne.org states that jojoba products are typically applied to the scalp, face and hands where sebum is most heavily localized. Unlike water-based moisturizers, the jojoba wax in L'Anza shampoo is designed to add shine and conditioning that doesn't evaporate quickly.
Biotin
MedlinePlus lists biotin as a likely effective treatment for hair thinning. Biotin is a water-soluble vitamin found in food that may affect the quality of your hair, nails and skin. L'Anza shampoos utilize biotin's knack at metabolizing fat and amino acids to create shields for hair follicles and shafts that prevents breakage. A 2008 article in the journal "Expert Review of Endocrinology & Metabolism" reports that biotin-deficient cells create hair loss through oxidative damage.
Keratin
Keratin is a fibrous protein that plays a significant role in the strength and overall quality of your hair, nails, skin and teeth, according to Keratin.com. Most of the keratins you readily come into contact with are remnants of dead cells that have pushed together to form an insulating layer over delicate developing hair follicles. L'Anza shampoos for dry hair employ this protective nature of keratin proteins to prevent hair breakage and boost hair growth.
