Having a bad hair day? Then buy new locks — from Jessica Simpson. For all her faults (mom jeans, that whole chicken-or-fish debacle), the girl has good hair, thanks in large part to her stylist BFF Ken Paves. So with Simpson's music career waning, the duo decided to open up shop hawking one of her assets that was still selling. Hairdo (get it?) Clip-In hair extensions are sold online and at beauty retailers like Sephora nationwide. They reportedly look fairly real and seem so simple that Simpson herself might be able to figure out how to use them.
