Jennifer Aniston’s Hair Care RoutineCredit : mrchrismcmillan/Instagram

Jennifer Aniston has long been a hair icon. Ten seasons of the beloved TV show Friends have shown fans and viewers Aniston's numerous hair transformations. The "Rachel" haircut was so iconic in the '90s. Aniston's character, Rachel, even made a joke about it in the show. Until now, any change in Aniston's hair makes the news and makes beauty editors perk up. Aniston just debuted blonde hair for her return to "The Morning Show." That Instagram post garnered over four million likes. In honor of her 52nd birthday, her longtime hairstylist, Chris McMillan, and colorist of nearly 30 years, Michael Canalé, share Jennifer Aniston's care routine with Vogue.

Bronde before blonde.

Canalé says Aniston is the "original bronde." In case you're wondering, bronde is the blend of brown and blond. It took years of gradually lightening Aniston's brunette locks to her signature beachy highlights and now to a full golden blonde. If you want to blonder, Canalé suggests going bronde first, especially if your skin is warm like Aniston's. To preserve your new hair color and bring out the blonde tones, Aniston's go-to gloss treatment is Canalé Midnight Blue Signature Gloss.

Double cleanse your hair.

Like many, Aniston doesn't wash her hair daily. When she does, she alternates between Drunk Elephant Cocomino Glossing Shampoo and Living Proof No Frizz Shampoo. She lathers, rinses, and repeats the process. McMillan recommends double cleansing to keep the scalp clean for a longer time. Next, McMillan says they condition from roots to tips with either Drunk Elephant Cocomino Marula Cream Conditioner or Canalé Soften Conditioner. McMillan assures that this practice doesn't make hair look flat. Spread conditioner over hair evenly with a wide-toothed comb.

Deep condition weekly.

McMillan reveals that Aniston makes time every Sunday for hair and scalp treatments. She uses The Living Proof Restore Mask and does a monthly "scientific brushing" treatment with McMillan to remove dead skin and buildup from the scalp. This brushing technique also boosts blood flow and promotes hair growth. For that they use Drunk Elephant T.L.C. Happi Scalp Scrub.

Commit to regular trims.

According to McMillan, Aniston is very consistent with her beauty routine. This includes getting regular trims every four weeks. Even a "baby trim," which means taking an eighth of an inch off your hair, will eliminate split ends.

Skip the curling iron and use fewer products.

As McMillan explains, Aniston doesn't like "manufactured" curls and prefers looser and more natural-looking twists. Instead of a curling iron, McMillan uses a blow dryer with round brushes of different sizes to achieve Aniston's trademark beachy waves. Less is also more when it comes to styling products. He mentions that Aniston hates hairspray but relents to McMillan when he needs it. McMillan's go-to hairsprays are Shu Uemura's Sheer Lacquer Micro Fine Finishing Spray and Oribe Superfine Hairspray. Fine hairsprays are key. As he points out, "Jen's hair always looks like you can touch it, it's not sprayed into place." To add some grit and body, he combines Shu Uemura Ishi Sculpt Texturizing & Sculpting Hair Paste with Kérastase Discipline Oleo Relax Anti-Frizz Oil Serum. He also uses small Velcro rollers at the crown on Aniston's hair to add volume and height.
