Jennifer Aniston hardly needs an introduction. From her iconic role on Friends to her more recent work on Apple TV’s The Morning Show and her success as the founder of LolaVie, the 55-year-old actress and entrepreneur seems to do it all. Despite her seemingly packed schedule, she recently sat down with InStyle to share her “guilty secret” for growing long, healthy hair, what her ideal self-care Sunday entails, and her go-to nail polish shade for autumn. Ahead, we’re digging into the key takeaways from the interview to take into your Friday.

On what goes into Jennifer Aniston’s ‘wash day’…

“I usually do a little self-care-Sunday situation. I do the [LolaVie] shampoo, meaning the scalp scrub, a conditioner, the leave-in treatment, and then I’ll put that up in a little bun while it’s settling in and doing its magic. And then I’ll do a facial scrub, a mask, and all of that stuff. Top to bottom!”

On how Jennifer Aniston’s hair ‘grew back so quickly’ after a shorter cut…

“Well, here’s my guilty secret. It’s extensions because I had to go back to shoot The Morning Show, and continuity-wise, I had to add a little length back in there. So that’s how fast that grew. [Laughs] The spiritual growth of that is called hair extensions. But I do have to say, my hair is growing at an alarmingly fast rate, and I really do owe it to the scalp scrub of just the overall use of all of the LolaVie line because it’s just changed my hair. I mean, even my hair colorist is like, ‘God, your face frame or whatever.’ If I do my color around my face, I think I’m usually a quarter of an inch or a half inch at four weeks. And now it’s like I’m averaging three-quarters of an inch. I mean, it’s growing fast!”

On how Jennifer Aniston switches up her beauty routine for fall…

“For fall, I usually change my nail colors, going from sheer pinks to deeper Bordeaux colors. But there are no real haircut or color changes. I don’t usually love trends. Whatever looks best on you and however you feel is best is how you should wear your hair.”
