Hair is largely made up of the protein keratin. why can a shampoo containing protein not replace the protein in damaged hair?
a. the process of replacement needs more time than we spend on washing our hair.
b. internal cell structures are assembled by living cells and cannot be replaced by molecules applied to the cell surface.
c. the hair's polypeptide is built up from amino acids, so shampoo must contain them instead of proteins.
d. cells synthesize proteins from amino acids, not from whole proteins in food or other sources.
e. proteins from a shampoo are synthetic and not organic as are the proteins of the hair.

What are protein keratin?

Keratin is a type of fibrous protein found in the human and animal body which is commonly found at the scales, hair, nails, feathers, horns, claws, and hooves.

These proteins are generated from amino acids but shampoos made up of keratin are not made for amino acids.

Therefore, the shampoo containing protein can not replace the protein in damaged hair because, the hair's polypeptide is built up from amino acids, so shampoo must contain them instead of proteins.
