HYDROXYPROPYLTRIMONIUM HYDROLYZED WHEY

Hydrolyzed Whey Protein

Safety grade: A

This ingredient is made from whey (a milk protein) that has been broken down into smaller pieces so it can be absorbed by hair and skin. It comes from a natural dairy source but is chemically processed to make it work better in cosmetics.

It helps reduce frizz and static in hair, adds moisture and softness to both hair and skin, and improves the overall feel and appearance of the product.
