This is the hair mask the clean beauty space has been waiting for: an ultraluxurious, salon-level deep conditioner that leaves your hair nourished, healthy, and full of shine. With tsubaki-seed oil for deep hydration and yuzu-fruit extract to smooth the cuticle, it is lightweight and smells amazing—that’s the Crown Affair signature scent of yuzu, lemongrass, and bergamot. To apply it, use a wide-tooth comb (like the one in the Crown Affair set) to distribute evenly. Leave it on for five to fifteen minutes—depending how dry or damaged your hair is—in place of or in addition to your regular conditioner.
