Hydrolysis is a type of chemical reaction where one reactant will create two or more products. Water is used because hydrolysis literally means reaction with water. Hydrolysis allows the hair to benefit from proteins breaking them down so they can be absorbed and aid the hair. Hydrolyzed soy protein is a water soluable protein derived from soy that strengthen and mend hair fibers. It increases the hair’s ability to hold moisture while adding shine and smoothness. Hydrolyzed soy protein has isoflavones, which have antioxidant effects on arming the scalp and hair from oxidative stress induced by UVB rays. They also enhance the hair’s gloss, texture, moisture retention, manageability and body. Hydrolyzed soy protein has commanded considerable respect as a scalp and hair-conditioning agent capable of reducing flaking, restoring suppleness and the well being of the hair and scalp alike.
