When "Friends" first aired in 1994, everybody fell in love with Jennifer Aniston's hair, and one of the most iconic hairstyles of the decade was born: The Rachel - now, two decades later decades later, the iconic actress talks about her hair secrets!

Of course, when it comes to the actress who played Rachel Green speaking about Jennifer Aniston's hair, the world is going to listen, and in a recent interview she mentioned all she's up for in the area of hairstyles, on things like whether she'd ever get a pixie haircut or go platinum blonde.

According to Entertainment Tonight Online, nobody could have seen the biggest discovery about Jennifer Aniston's hair coming: she actually uses sweat as a hair product! The actress stated that, even after working out, she doesn't necessarily wash her hair in the days between training sessions, as she likes to keep her hair a little sweaty.

The interview about Jennifer Aniston's hair came out in the latest edition of Fashionista, as the actress spoke about her recent photo shoot with her hair stylist, Chris McMillan, the man who created The Rachel and has been the man behind her different hair choices for the past two decades.

During the Jennifer Aniston hair interview, the actress was asked a number of things about her relationship with her stylist and whether she'd like to try different new styles, like getting a pixie cut or go platinum blonde - and she's said that she absolutely would not go for either of those, even though McMillan has told her over and over to try these out.

In other words, she's said that she has no intention of following trends, not even if they're being set by Kim Kardashian!

As Us Weekly reports, besides being a trendsetter herself through the different options of Jennifer Aniston's hair, the actress is the co-owner of a hair care line called Living Proof, in which she works with McMillan.

"I don't like [to wear] my hair up very much. I'm not an undo kind of gal." said the actress about Jennifer Aniston's hair. "I feel like if you're wearing a gown with glitter, you want to have beach, natural hair to kind of go against that. So that's sort of my main thing, being me."
