keratin treatment and review
The keratin treatment is considered safe for hair sinceit uses the natural protein found in the hair shafts and is suitable for most hair conditions. The treatment straightens the hair, reduces frizz and adds a shine. The results last approximately 6 months and gradually returns to the original texture.
Keratin is one of a family of structural fibrousproteins also known as scleroproteins. Alphakeratin (αkeratin) is a type of keratin found in vertebrates. It is the main structural material thatmakes up the scales, hair, claws, feathers, horns, claws, hooves, and outer layers of the skin of vertebrates. Keratin also protects epithelial cells from damage and stress.
Keratin is very insoluble in water and organic solvents. Keratin monomers bundle and aggregate to form intermediate filaments that form thetough, non-mineralized epidermal appendages found in reptiles,birds, amphibians, and mammals. Excessive keratinization contributes to the strengthening of certain tissues, including B. bovine and rhinoceros horns, and dermal bones of armadillo. Keratin comes in two types,the primitive, softer forms found in all vertebrates and harder, derived forms found only among sauropsids (reptiles and birds).
lphakeratins are found in all vertebrates. They formthe hair (including wool), the outer layer of skin, horns, nails, claws and hooves of mammals, and the slime threads of hagfish. Keratin filaments are abundant in keratinocytes in the hornified layer of the epidermis; these are proteins which have undergone keratinization. They are also present in epithelial cells in general. For example, mouse thymic epithelial cells react with antibodies for keratin 5, keratin 8, and keratin 14. These antibodies are used as fluorescent markers to distinguish a subset of mouse thymic epithelial cells in thymic genetic studies.Keratin (also known as cytokeratin) is a type I and type II intermediate filament polymer found only in vertebrates (vertebrates, amphioxus, tunicates). Animalsother than nematodes and many other chordates appear to have only type VI intermediatefilaments, the fibers that make up the cell nucleus.
