London, Apr 15 (ANI): Katy Perry has started wearing blue wigs, as her own hair had started getting damaged due to constant colouring.
The 27-year-old has apparently a whole suitcase full of different-coloured blue wigs.
"Katy's own hair began to get damaged because of all the dyeing, so she's started wearing wigs," the Daily Star quoted a source as saying.
However, the pop star doesn't want fans to notice her wig.
"Katy wants the wigs to look as real as possible so they are all cut and styled by her own hairdresser," the source added. (ANI)
