Kylie Jenner has an ''addiction'' to changing her hair.

The 18-year-old reality TV star has admitted she's obsessed with sprucing up her look with different colours and cuts because it makes her feel like a ''new person.''

Writing on her website, she said: ''I first dyed my hair when I was 16. I dyed it blue and I never even asked my mom. After that, I've just had this addiction to changing my hair.''

She added: ''It makes me feel like a new person. I love feeling different and I love leaving the house knowing that nobody has ever seen me this way.''

But the 'Keeping Up With the Kardashians' star believes her love of hair products has damaged her luscious locks, so she now uses wigs to give her a different look every day.

She explained: ''Because I change my hair so much, it's become damaged. I've had to find ways to really try and take care of it and give it a rest. I discovered this amazing wig guy, Tokyo, and together we create wigs.

''Wigs are just SO much easier because I change my mind so much and this way I'm not damaging my hair.''

Meanwhile, Kylie - who is dating rapper Tyga, 25 - recently launched her own hair extension line with Bellami.
