Or at least see what you look like in a different hair color or style? The girls and I had way too much fun and spent way too long playing on the Clairol site. It will let you upload a face shot of yourself (with hair pulled back) and try a zillion combinations of hair color and style. You do have to register to use it.
We don't intend to go blond, or walk around in Hollywood hairstyles. But, I admit, we especially liked the 'glamorous' hair on us. :)
