20 Products You Need to Buy the Day You Turn 30

Why: At 30, it's time to be comfortable in your own skin — or rather, hair. Make this the decade you embrace your natural curls and air-drying.

Try: I have naturally curly-wavy hair and found that light gels, like Kérastase Curl Fever ($29), give it the best texture. I even use this before I blow-dry, and it's never sticky or crunchy. The lightweight formula gives me just enough grit for natural or hot-tools-styled coils.
