A hydrolyzed wheat protein is a whole wheat grain that has been dissolved into its basic amino acid form. In hair products, it acts as a conditioning agent, which repairs hair by hydrating strands and saturating the follicle with protective, revitalizing nutrients from the inside-out. It also improves hair’s ability to hold onto moisture. Not only does added moisture enhance the volume and texture of hair, but it is also known to bestow a healthy shine.
