Los Angeles:- Reality TV personality Kylie Jenner first dyed her hair when she was a mere nine years old. The 18-year-old, who has a huge stash of fake hair, believes her fascination with collecting wigs began after she started to experiment with hair colouring, reports femalefirst.co.uk. Taking to her Twitter account, Jenner posted a photograph of her younger self with a thick blonde highlight streaked through her dark locks. She accompanied the shot with the caption: "I begged my mother for a year to dye my hair and finally at nine-year-old she let me do this and only this! Changed everything." Meanwhile, the “Keeping Up With the Kardashians” star, who recently became the face of the sportswear brand Puma, is constantly experimenting with her tresses but she has admitted there is one trusty hair piece she always turns to. "My favourite is the plain black one with bangs. When my hair's been braided or it just doesn't look good. I'll wear it for the day, which is so easy. “I've never been shy about the fact that I wear wigs, so I thought it would be really fun to show everybody my whole collection. I've got 15 altogether,” she said.
