Does anyone use Bumble & Bumble Surf Spray? It's a spray that's supposed to give you the "beach hair" loook - natural, wavy, and kinda windblown - you know, the way your hair looks after you get out of the salt water and it dries. Anyway, all I've seen online were RAVE reviews of it. I went to my salon and bought it ($18 for 4 oz. - I was pleasantly surprised, though, since online they said it was between $23-$27), and it looks GREAT while my hair is drying, but later in the day, my hair just kinda looks lumpy. I'm not sure if I'm doing it right, or how to really use it. Any tips from anyone who has it?
