Keratin is a basic component of hair, skin and nails.
This type of protein is also contained in some organs and glands. Keratin is less exposed to scratching or tearing than other cells of human body. They say keratin helps hair become smoother and more manageable. It goes without saying that results can be different as they depend directly on the initial state of hair, its structure and a type of keratin treatment you choose. Keratin smoothes the cells that overlap to make hair locks.
The hair cuticle, the part of the hair shaft, consists of cells that absorb the keratin, which makes hair look healthy and shiny. Keratin also helps to tame frizzy and unruly hair. Due to keratin treatment hair becomes much easier to manage. As it has been mentioned, there are various types of keratin treatments. One of them is Brazilian keratin treatment; it comprises several stages and "wears off" only after 12 weeks.
