A friend had this in her Birchbox, and it was THE product that turned me on to Birchbox. I thought to myself, If the samples are at all consistently like this one, I want. For someone with with, difficult-to-style hair (like ME), this is a dream product. It holds like crazy (and YES, does feel a little stiff on the hair, but you have to do the cost-benefit analysis: little cost, big benefit) throughout the night, whether you're doing curls, waves, or going straight. Really, truly good stuff.
