The actress has admitted in previous interviews that her hair-care routine is very minimal for the most part, but there's one product she reaches for the most when she wants to look like she just stepped out of her stylist's chair.
"This is like the only thing I do to my hair, other than wash it: I use a night serum," she said, referring to the Kerastase Nutritive 8H Magic Night Serum ($56) based on her description. "I've been using it for years. I put it on mid-to-end of my hair, and it makes my hair feel like a baby's bottom. That's a weird analogy, but it's so smooth and soft and it feels like freshly-washed, just blow-dried hair every time I use it."
