What It Does

Brown Rice Protein is a plant-derived hydrolyzed protein obtained from Oryza sativa (brown rice), extracted from the bran and endosperm layers that are retained during minimal milling. It is rich in amino acids such as glutamine, arginine, and cysteine, which help strengthen the hair shaft and support skin barrier function by binding to keratin and forming a protective film. Formulators favor it as a vegan and hypoallergenic alternative to animal-derived proteins like hydrolyzed keratin or silk, making it especially appealing in clean beauty and allergen-conscious formulations for both hair care and skincare.
