So apparently we need a warning not to use glue on hair. There is a whole section dedicated to hair care products and glue is in a different place in the store.
Gorilla Glue GirlTM may be suing for the glue sticking things together and only warning not to use it on eyes, skin or clothing, but not hair. Scalp is skin, hopefully a judge allows that fact before the price of Gorilla Glue triples to cover the cost of litigation.
