This is my top choice as it doesn't have a noticeable smell and it provides the tousled beach waves I love.
Got2b Beach Trippin Salt Infusion Waving Spray, 6.8 Fluid oz
It does a great job providing the tousled beach waves and you get slightly more in the bottle, but it has a slight vinegar smell. I wouldn't consider it a deal breaker but it does make it my second choice.
My favorite way to use sea salt sprays, apply to hair after shampooing and allow to air dry either scrunching the hair as it dries or putting it up in a twisty bun for even more waves, when I take it down.
