10 Brilliant Tweaks That Suddenly Made Actors Cool As F***

It's not exactly a secret that Friends launched the careers of its six lead actors, but in the case of Jennifer Aniston, she made one particular tweak to her appearance which transformed her from a well-liked actress and sex symbol into an outright style icon.

In the first season's 20th episode, "The One with the Evil Orthodontist," Aniston debuted what would be called "The Rachel" - her iconic layered shoulder-length haircut, as designed by Aniston's hairstylist Chris McMillan.

Almost immediately after the episode aired, the haircut became a major talking point in general culture, with The Rachel becoming the most popular and requested female haircut for the entire decade that followed.

Close to three decades later, The Rachel remains one of the world's most famous 'dos, and one that's enjoyed countless revivals over the years.

Without it, Aniston simply wouldn't be nearly as influential a public figure as she undeniably is, literally shaping how tens of millions of women wore their hair overnight.

Ironically, though, Aniston herself isn't much a fan of The Rachel due to its difficulty to maintain without the assistance of a stylist like McMillan.
