Brazilian Keratin is a family of fibrous structural proteins. Keratin is the key structural material making up the outer layer of human skin. It is also the key structural component of hair and nails.Keratin monomers assemble into bundles to form intermediate filaments, which are tough and insoluble and form strong unmineralized tissues found in reptiles, birds, ambians, and mammals. Studies have shown topical application of hydrolysed keratin gives significant increases in skin elasticity and hydration.Due to its moisturising properties, hydrolysed keratin has also been incorporated into shampoo and conditioner.Larger keratin structures such as those formed by cornification cannot penetrate the skin so cannot be used as moisturisers. However there are other uses, from hair loss concealing products using fine hair fibres to hair thickening accessories like hair extensions.We use the keratin to strenghthen hair,nourish the scalp and the hair as a keratin hair treatment.
