The 41-year-old former star of "Friends" says in the February issue of Allure magazine that "The Rachel" was not her best look.
She says: "How do I say this? I think it was the ugliest haircut I've ever seen."
Aniston wore the style on the show's first and second season, and it quickly caught on at salons across America. It was named for her character, Rachel Green.
Aniston's longtime hairstylist Chris McMillan came up with "The Rachel." He still works with her today.
