Jennifer Aniston quietly revealed a new, considerably shorter hairstyle on Monday, Nov. 4, but people everywhere are buzzing about her dramatic makeover! Aniston's hair colorist, Michael Canale, told reporters more about her transformation.

The 44-year-old star's new style -- a messier version of the bob parted to the side and stopping at her jaw line -- was actually the result of a bad Brazillian blowout, Aniston revealed to Elle in an interview. "My hair did not react really well to it," Justin Theroux's fiancee said of the straightening treatment. She also told Vogue, "I'm always one of those girls who does a big old chop just to get it really healthy, to repair all the [damage from] hair coloring and stuff like that."

Therefore the challenges for Aniston's longtime colorist Canale (who, like stylist Chris McMillan, has been handling the Friends star's hair since her iconic "Rachel" days) were infusing Aniston's already chemically-damaged locks with a color that would revive it back to a healthy and glossy state, and finding an appropriate hue to complement her new cut.

Canale explains: "First, I had to remove the warm colors from the top section of her hair, and I really made a point to emphasize extra blonde around her face and along the sides, about a quarter inch in from the hairline so it blended fluently with the rest of her hair." Then the expert opted for a "baby blonde color as opposed to the sandy blonde color that she came in with" for two reasons: "To maintain felinity and accentuate her natural beauty," he says in the release.

Finally, the celebrity color guru added "paper-thin highlights all-over," which creates "a gorgeous, natural-looking sheen." Canale explains, "It also ensures you aren’t over-bleaching hair that’s already parched." And voila! Hot hair for one of the most high profile stars in the world.

The results seem to be working well for Aniston, who explained to Vogue, "I did it! I feel great. I feel lighter. It's simple, it's really simple, that's for sure."
