Aveda is introducing a new styling product designed to add volume. Apply Pure Abundance Style-Prep to damp hair to detangle and add natural, weightless volume. How much volume you ask?  Aveda promises a 20 percent instant, all over increase that lasts all day, thanks to  a 95 percent naturally derived formula (with a fresh, minty aroma). I tried it on a non-shampoo day. Pure Abundance is not a dry shampoo, but it will restore some bounce. Look for Pure Abundance Style Prep in stores and salons in July. It sells for $24.
