Sham the Pooh

Theres a shampoo which claims to have some ceramic cement in it; another wich claims to have some oil of dubious origin;yet another wich claims to clear ur scalp of everythng; yet another wich claims to add gloss n shine ur hair....just like cherry blossom.....
Am i missing something? thot shampoos were just diluted sodium lauryl salts wich cud b whippd up to a foam
