Medusa is a mythological figure with snakes for hair, but she’s also a Marvel superhero. And wouldn’t it make for a great shampoo commercial to show how Medusa used to be all angry and turned people to stone because her hair was so dry that it turned into vicious snakes out of rage, and they dried out anyone who saw her until they became stone out of vengeance, since she was so embarrassed to have such unsightly hair, and she didn't want them telling anyone? Oh, but once she tried Garnier Fructis shampoo, her hair became so happy, it got super powers! So now she fights for right with her super strong, healthy hair as the Marvel Comics heroine Medusa! (And you can become a superhero too, when you use Garnier Fructis shampoo!*)
