I think Bumble+Bumble makes one too(a salt spray) and John Frieda used to as well, I've never used them as I have wavy hair and so am always wanting pin straight, LOL, but friends ahve and it looked really good.
Here is the drugstore.com item. Gotta love it if only for the name! I'm going to try it. Along with continual sleeping in braids.

THANKS EVERYONE!

What is Solarshield?
Solarshield is an innovative sun protection technology developed by Frederic Fekkai that combats the effects of UV rays on hair. Solarshield harnesses the full power of Sunflower Seed Extract and Moringa Seed Extract, which work synergistically to condition and help protect the hair from the effects of UV rays, pollutants and other environmental stressors.
What are the damaging effects of UV exposure?
Fekkai's Solarshield technology is designed to defend against the damaging effects of UV rays.
UV rays...
compromise core strength and elasticity.
can cause photo-oxidation of amino acids, triggering discoloration and fading in both natural and chemical hair colors.
The result? Dry, dull, brittle, lifeless-looking hair.
Tips from Frederic.
During the summer, no matter what type of hair you have, chlorine, sun and salt can wreak havoc on it. Protect your hair to the maximum with my new, expanded Summer Hair Collection, and help fight 3 of the most common summer hair problems:
Problem 1: color fading
Solution: Whenever you plan to be in the sun, and especially before you go in the pool, be sure to apply a generous amount of Sun Bandana throughout the hair to protect your color. Once you're out of the pool, always rinse with fresh water. Then, reapply Sun Bandana.
Problem 2: limp locks
Solution: For sexy, tousled waves, play up the natural texture of your hair with Beach Waves. Locks can also go limp after a long day at the beach. Before you head for dinner, freshen and revive your style without shampooing with Wash & Wear.
Problem 3: dry, frizzy hair
Solution: Start with a trim to get ends back in shape. Opt for a cut with fewer layers to minimize frizziness. When it's really humid and hot outside, spritz Zero-Humidity Frizz Control on clean, damp hair to block out frizz and fly-aways all day. If your hair is feeling parched, give it an instant moisture boost with Quick-Quench Rehydrating Gelee.
