Jessie J has revealed that she will always prefer wigs to extensive hair-styling because it saves her locks from falling out.

Although the vocal sensation announced plans to shave her head for charity last year, she explained to Glamour magazine in a new interview that it makes more sense for her to change her look with hair pieces to stop it getting damaged:

"It's tough to explain to people. When you have half an hour to be ready at four o'clock in the morning, you don't have time to get up and glue in extensions or blow-dry your hair." 

"A hairdresser who did my hair said, 'You, my darling, have something that we call 'successful' hair', which is basically battered hair that's split and falling out in the back because you've had to blow-dry it every day. I don't want my hair falling out, so I wear wigs!"

She also admitted that despite being a pop star she doesn't really immerse herself in the stereotypical lifestyle and isn't really a "party person" at all:

"I'm young, and having one drink is [enough]. My [calendar] is just unreal at the moment. I don't have time to be tired!"

"You need to choose when you have your celebration and make it special instead of going out every night and exhausting yourself. I'm not really the party person. I don't 'become myself' once I'm drunk. I don't use alcohol to be happy."
