Silk Protein is an ingredient found in many varieties of shampoo and conditioner. It is a hair conditioning component infused with additional enzymes. A Hydrolyzed Silk Protein is said to be a combination of naturally occurring lipids from palm oil and the protein derived from silk, or amino acids. Silk protein is said to add luster and shine to hair by infusing strands with beneficial amino acids that facilitate hair’s manageability. It is noted to retain 10,000 times its weight in water, aiding in superior moisture absorption. This valuable ingredient possesses no toxicity or threat to health, according to the Environmental Working Group (EWG).
