Although hair is made of protein, it’s dead. So putting protein on top of the protein in your hair doesn’t make it “healthy.” But the right kind of proteins used at the right levels can act as conditioning agents that form a protective film on the hair. So it’s not that your hair needs protein, it’s that it needs something to form that protective layer.

Proteins will do it to some extent, but there are other ingredients, like fatty quaternium compounds or silicones, that will work even better. So protein conditioners like Mane ‘n Tail are good for your hair, but not necessarily because they contain protein.
