How keratin effects on your hair?

Keratin is the type of protein that makes up your hair, skin, and nails. Keratin can also be found in your internal organs. Keratin is a protective protein.

Keratin can be derived from the feathers, horns, and wool of different animals and used as an ingredient in hair cosmetics. Since keratin is the structural building block of your hair, some people believe that keratin supplements, products, and treatments can help strengthen your hair and make it look healthier. People who use keratin on their hair report that their hair is smoother and easier to manage as a result.

The effects vary greatly depending on whether your hair is healthy to begin with, what the natural thickness of your hair is, and what kind of keratin treatment you use. Keratin works by smoothing down the cells that overlap to form your hair strands. The layers of cells, called the hair cuticle, theoretically absorb the keratin, resulting in hair that looks full and glossy. It helps to repair cracked and weak points, because it is rich in protein and vitamins, and revitalizes seals split ends.

It is excellent for hair that has been painted with dye, since its effects repair the damaged fibers, hold the dye color and grant it an enviable brightness.
