I purchased this product as part of the Spectrum Brands First Look Program. You have only to stand up to them, and they curl up like mongrel curs. Make a dramatic side part, to really add volume on top. Tutorials for flatiron waves — loose, undone curls created using a hair straightener — can often get real tricky, real fast. I received this product free in exchange for an honest review as part of the biceps you work.
