50 Worst Hairstyles of All Time

From the site:

It is said that hair makes the man, and certainly women go to amazing lengths to find a style that will at once enhance their looks and set them apart from other women. Sometimes the pressure and lengths traveled lead to styles and cuts that are just plain terrible. From the old standbys of ugliness like, The Mullet and Comb-Over to new additions to the bad hair lexicon like, The Career Terminator and The Gangsta Pimp- they are all here.

I couldn't have said it any better.
