In the midst of some personal problems and erratic behavior in early 2007, Spears checked into a drug rehab clinic in Antigua for less than a day in February. After she checked out, she shaved her head with electric clippers at a Los Angeles hair salon, with the resulting photos going viral. Pictured here is an eBay auction for Spears' locks of shorn hair put up by the hair salon.
