Since I started coloring my hair more than 20 years ago, it’s become less soft, and my highlights can get a bit brassy. But I’ve found some help with the violet pigment in Sachajuan Silver Shampoo ($28, sachajuan.com), which keeps the blonde (left) from venturing into orange territory. Pantene AgeDefy Conditioner ($9, pantene.com), meanwhile, smooths pesky split ends as well as unruly grays. And once a week I bring a magazine into the bathtub after I slather NeuMoisture Intensive Masque ($35, neumabeauty.com for stores) all over my head. The treatment smells divine, and it’s packed with plant extracts and essential oils—which is why I let it stay on much longer than the recommended two to three minutes.
