If it's silky hair you're after, here's a double dose of help: Dove Hair Nourishing Oil Care Daily Treatment Conditioner. Each squeeze of the bottle gives you two ribbons of conditioner: The white ribbon contains softeners that repair damage and seal the cuticle to reduce frizz and lock in nutrients; the yellow is infused with a mix of nourishing oils that penetrate hair, leaving it smooth and shiny.

One of the reasons I especially like this sunscreen is that when you shake the container (as directed) before you apply, it makes a satisfying little rattle. There's even a name for it, coined at the Japanese lab where the sunscreens were first produced: "shaka shaka." The sound comes from the small ball bearing that helps emulsify the fluid. Now there's a new "shaka shaka" sunscreen: Anthelios 50 Mineral. It offers broad-spectrum protection in a 100 percent titanium dioxide formula. It's lightweight, there's no residue, it contains no PABA, parabens, or fragrance, and it's water resistant. I tried it (after I got my shaka-shaka thing on, naturally), and though I can't tell you what else I'll be wearing this summer, I know I'll be wearing this. —Valerie Monroe
