To say that Prive Finishing Texture Spray, $22, plays nice with other products is an understatement. It's one of the lightest dry texturizing sprays out there, so you can layer it with anything. If your hair gets flat throughout the day, this is the one you'll want to stash in your desk to amp it up.

Redken Cerafill Texture Effect Hair and Scalp Refresher, $18, is part of Redken's new line of shampoos, conditioners and stylers designed for thinning hair. It's an excellent oil absorber and creates plenty of volume -- so hair appears fuller while the other Cerafill products help hair grow fuller long term.
