Artificial hair integrations is a type of synthetic fiber that can withstand heat up to 400 °F (200 °C), and can actually outlast human hair. It is very similar to human hair given it is tangle-free and has a natural sheen. It can be straightened or curled, however, it takes longer to set and futura cannot be colored. It is sometimes sold as a human hair blend. The human hair shaft is made up of dead, hard protein, called keratin, in three layers. The inner layer is called the medulla and may not be present.

Soy protein defatted soy meal/flour. All of these processes result in a product that is 70% protein, 20% carbohydrates (2.7 to 5% crude fiber), 6% ash and about 1% oil, but the solubility may differ. One tonne of defatted soybean flakes will yield about 750 kg of soybean protein concentrate. Processed soy protein appears in foods mainly in three forms: soy flour, soy protein isolates, and soy protein concentrates. Soy protein isolate is a highly refined or purified form of soy protein with a minimum protein content of 90% on a moisture-free basis. It is made from defatted soy flour which has
