I use this all the time before using the curling iron. In fact, I spray each section of hair just before I curl it. I don't know whether it protects hair, but I've been doing this for several years, and my somewhat long hair has not experienced any terrible drying side effects like you might expect from using a hairspray that way. Sure when you use a curling iron right after spraying, the curls are stiff until you run your fingers or a brush through, but I don't notice any lasting difference in texture (not like when I overdo it on mousse or gel). It's not strong enough to hold my hair like a hairspray after styling, so when I'm done I still need something more.

I used it before hand, because that is also what it said in the store fixture information, and I was seriously disappointed by the results.
