Paris Hilton has a simple way of blending in when she wants privacy - she wears a brunette wig. The socialite revealed that she switches to a brown wig to go incognito at places like Disneyland or the mall. Hilton, known for her iconic blonde hair, avoids permanently dyeing it brunette due to potential damage. She recently returned to her signature blonde look for a fashion show, but she and Nicole Richie are planning a new project together after their iconic show, The Simple Life.
