Natural fiber Keratin is a structural protein located at the hard surfaces in many vertebrates. Keratin has two forms, α-keratin and β-keratin and are used by different classes of animals. The naming convention for proteins follows that for keratin, alpha keratin is helical and beta keratin is sheet like. Alpha keratin is found in mammalian hair, skin, nails, horn and quills, while beta keratin can be found in avian and reptilian species in scales, feathers, and beaks. The two different structures of keratin have dissimilar mechanical properties, as seen in their dissimilar applications. The relative alignment of the keratin fibrils has a
Hair gel punk subculture in the 1980s. Some hair gels include temporary hair coloring, which includes variants in unnatural colors associated with various subcultures, such as the goths, ravers, and greasers. In films and on television, mobsters and government agents are also well-known for using hair gel in similar ways to each other, goths, and greasers. Cationic polymers are among the main functional components of hair gel. The positive charges in the polymers causes them to stretch, making the gel more viscous. Hair gels resist natural protein conformations and allow hair to be styled and textured, because the stretched-out polymer takes up
