Kim Kardashian shocked onlookers at Charles De Gaulle airport g when she arrived for Paris Fashion Week sporting a large bald spot. The 31-year-old reality star was seen with a thinning patch at the side of her head. It seems that Kim is paying a high price for her frequent use of hair extension. Naomi Campbell, Alexandra Burke and Tamara Beckwith have all suffered from hair loss as a result of over-tight extensions and weaves, and just general hair abuse. Trichologists say that quite often with celebrity hair thinning or loss nowadays, hair extensions are to blame.
