What's the easiest way to add body to my hair?

—Renee Henry, Little Valley, N.Y.

Bobbi: I turn my head upside down and add a lifting mousse to my roots while it’s still damp. The key is to not apply it on top; you have to get it underneath, right at the roots. I also find adding loose curls or waves helps give my hair extra body. There are even little pocket-sized curling irons you can throw in your bag or stash at the office if you need to re-curl or add body at the end of the day.

Twirl with: TS-2 Go Curl Mini Curling Iron ($35; amazon.com/beauty)
