Blake Lively doesn’t do conditioners. When she played Serena Van der Woodsen on Gossip Girl in the early aughts, she noticed that the show’s hairstylists only used masks after shampooing her hair. “They were like, ‘Oh God, no, we don't use conditioners,’” she told Allure in a previous interview.

Since then, she’s been conditioner-free—and hopes that now, you will be, too. In its place, you’d use her hair-care line’s Blake Brown Beauty Fundamental Nourishing Mask, which is chock-full of glycerin and sunflower seed extract to deeply hydrate and soften hair.

Even after just twisting off the tub’s gold top, it was clear to us that its cozy cardamom and cedarwood scent is worth the switch alone. Can you tell we’re big on fragrance here at Allure?

Like most hair masks, this one was formulated to be used after shampooing and rinsing. Instead of your go-to conditioner, you’d rake a dollop of this thick, butter-like cream into hair, starting from mid-lengths and working down to the ends.

The brand recommends leaving it on for two to five minutes (a good time to shave your legs, wash your body, or just vibe), then rinse it out for smoother, shinier strands come dry time. We found the best, most consistently shiny results after using it once a week. Thanks, Blake!

You can find the Blake Brown Beauty Fundamental Nourishing Mask, along with other editor-loved products, in the January Allure Beauty Box.
