Hydrolyzed protein is one of the most common ingredients in haircare. Wheat protein, soy protein, oat protein, rice protein, quinoa protein — all hydrolyzed (broken down into smaller fragments) and added to formulas to support hair fiber integrity.
The problem: free hydrolyzed protein rinses off. It provides a temporary smoothing effect, then it’s gone with the next wash. To stay on the hair, the protein needs an anchor to the cuticle.
This is where Hydrolyzed Vegetable Protein PG-Propyl Silanetriol changes the equation.
