<Keratin amino acids
Molecular weight 90-200: Keratin derived from human hair and most suitable for repair.
By bonding with keratin derived from waterfowl, it becomes a high molecular weight (20,000) and shows excellent hair repair, moisturizing effect, and strength recovery.
<Meadowfoam-lactone
Heating causes bonding (amide bonding) with the amino groups of keratin. The excellent adsorption property allows it to remain in the hair and make it hydrophobic. It is expected to repair, moisturize, prevent static electricity, and improve the hair's combing action.
<Wool-derived hydrolyzed keratin
Molecular weight 30,000: Hydrolyzed polymer keratin derived from wool.
It forms an excellent film, giving the hair elasticity and luster while improving manageability.
