20 Products You Need to Buy the Day You Turn 30

Why: Whether you've been coloring your hair for years or realizing your mane feels a bit drier, you need to have a solid moisture mask on hand. As we age, our skin and scalp produce less oil, which results in coarser strands. It's an easy shower remedy by swapping your daily conditioner for a once-a-week heavier version.

Try: When I tell you the ingredients in Oribe's Gold Lust Transformative Masque ($62), you'll understand why it smells so amazing. White tea leaf extract softens strands, jasmine nourishes, shea butter improves elasticity, and baobab oil (from the African baobab "Tree of Life") offers revitalizing vitamins A, D, E, and F. Basically, it packs in everything that's good for you to deliver lustrous locks.
