It would be easy to blame recent volatile weather for the current epidemic of out-of-control celebrity hair. But extreme winds and heavy precipitation couldn't even begin to explain the middle-school-bangs crimped-locks combo Sharon Stone has been sporting lately.

How else to explain the pompadour atop her noggin? Ashlee Simpson recently dyed her dark locks into a freaky, platinum What Ever Happened to Baby Jane? 'do.

''A lot of times things are done too much on the fly...two hours before a live red carpet,'' says hairstylist Kevin Mancuso, who has worked with Britney Spears and Jennifer Connelly.
