The Rachel haircut, also called the Rachel Shag or just The Rachel, is a bouncy, square layered hairstyle introduced by Jennifer Aniston in season 1 of the hit American sitcom Friends and named after her character, Rachel Green. Many women in the 1990s cut their hair in the style.
The style is claimed to have been created by Jennifer Aniston's hairstylist, Chris McMillan. The Rachel haircut became popular among young women and was copied the world over, becoming the 1990s equivalent of Farrah Fawcett's 1970s flip. Aniston only wore that particular hairstyle during the Friends' first and second seasons — at the beginning of the third season, she switched to a more traditional long-haired look — but it has become associated with the character. In the second season episode "The One With the Lesbian Wedding", Rachel Green moans that her mother (Marlo Thomas) is trying to pattern her own life after hers, lamenting, "Couldn't she just copy my haircut?"
