[Haskell-beginners] homogeneous value list

Hi. I know, this is a very basic question but I've had some trouble with it. I've a list and I want to write a function isHomogeneous :: [String] -> Bool returning True is all the elements of the list are equals and False otherwise. In my first ugly test I've used a list-comprehension method, but I'm sure that exists a more elegant/short way to obtain the same result. Thanks in advance for any answer.
