Jennifer Aniston has revealed the secret to her much-envied hairstyle.

In the October issue of Redbook magazine, Aniston says she usually doesn't blow-dry her hair.

"I usually shape the hair around my face with my fingers - just twist it and then refine it with a brush and let it air-dry," she says.

Aniston also reveals that she uses as much hair product as fiancé Justin Theroux, and that she would never try red lips.

"Super bleached blondes - like Gwen Stefani - can get away with it, but it's tough to pull off with my colour," she says.
