So since I moved to LA in September, I've definitely been spending much more time in the sun than ever.  Relax, I always wear SPF but I'm still concerned about two things- my hair and my scalp.  I've pretty much always had thin hair and I remember getting some pretty bad scalp burns in high school...which end up looking like dandruff when it heals- very attractive.  Anyway, I recently received Redken's Color Extend Sun Solar Screen SPF 12 ($16 at salons) and I'm obsessed.  It's the perfect spray product to protect my scalp from getting burned in the sun AND it also guards my blonde highlights from fading to that god awful brassy orange color.  Yuck.  It's really a great multi-tasker...Redken's exclusive Interbond Conditioning System and the advanced Hydra-Shield Complex deliver strengthening Ceramide and moisture-rich Mango Oil to dry strands to resurface the cuticle, repair damaged areas and replenish lost moisture in your hair.  I'll be carrying this around me all summer, especially since I've decided to really learn how to surf this year. ;-)  Stay tuned for updates.  I sense this product will get "life changing" status.
