ROSIN HYDROLYZED COLLAGEN

Safety grade: A

This is a combination of rosin (a sticky substance from pine trees) and collagen (a protein that gives skin and hair their structure) that has been broken down into smaller pieces. It works as a film-forming agent that coats hair and skin to provide conditioning and hold.

This ingredient creates a protective coating on hair and skin to improve conditioning, add shine, reduce frizz, provide long-lasting hold, and enhance overall texture and appearance.
