* Moisture Control Shampoo  Hyaluronic acid, a natural moisturizing substance, forms a protective layer on the surface of dry, brittle hair to retain moisturization. Then, ?-cysteine works deep within the hair for resilient styling.  

* Moisture Control Conditioner  Hyaluronic acid, a natural moisturizing substance, and a moisturizing conditioning agent keep hair moisturized and neat.

[What is ?-cysteine?]
* Strengthen keratin that enhances resilience!  Keratin has four types of bonds that strengthen the bonds between molecules.
One of them is a bond between cysteines: an S-S bond that maintains and enhances the elasticity of hair. When cysteine is supplied externally in order to restore keratin damaged due to a lack of cysteine deep within the hair, it is absorbed by the hair and forms bonds to solidify the hair structure and make hair appear more resilient.

* When hair appears weak and limp, suspect a shortage of cysteine!  Keratin is a key component that accounts for about 80-90% of hair and of which 14-18% is made up of cysteine. A kind of amino acid, cysteine forms one of the protein bond structures found in hair.  A cysteine deficiency results in weak protein bonding and causes weak and limp hair that appears dull and brittle, and, in extreme cases, split ends.

* Packed with cysteine from the surface to within! Made up of about six amino acids, cysteine not only adheres to the surface of damaged hair but also penetrates deep within the hair to revive brittle, damaged hair and help restore elasticity and health.
