Hydrolyzed soy protein is a vegetable-derived source of protein. It is an isolated form of protein extracted from the soy bean. Soy protein has been recognized as a beneficial ingredient in both hair and body products as it improves the ability to absorb moisture. According to sources, soy protein can allay damage done to hair through dying, bleaching, perming, straightening and smoothing with a hot comb. It can also mitigate dry or chapped skin caused by environmental factors. It is known to improve hair manageability and create a healthier body and texture. Soy is also known to contain Isoflavones which are believed to abate signs of hormone-linked aging. Aside from having many beneficial health aspects, soy protein can also be used in formulas as a natural emulsifier to enhance a product's composition.
