This week in SPF You Didn't Know You Needed—or perhaps just SPF Emily Didn't Know She Needed—is hair sun protection. Being a hair color virgin might be the stem of my ignorance. That, and the fact that I'm consistently begging the sun to bleach my hair so that I don't have to pay a colorist to do it. Anyway, I've been told that protecting my skin but not my hair is a generally terrible idea, and I really should be doing both. Hence, this post and the following three products. Each suit a slightly different need, so read carefully:

Sachajuan Hair In The Sun

First off, great name. Secondly, great packaging. Gotta hand it to the Swedes. But more importantly, it's a UV shield for your hair (so you can only fry it when you want to). This should be of particular interest if you're someone who colors their hair—it'll prevent any brassiness or fading. If your propensity for fantastic product names has not been fulfilled, there's Hair After The Sun to re-moisturize and smooth frizz...after the sun.

Philip Kingsley Swimcap

UV protection is important; chlorine protection is probably more so. Philip Kingsley developed Swimcap for the US Olympic Synchronized Swimming Team for obvious reasons. Now the cream is amped up with sun protection to safeguard against any color damage you might otherwise run into while working at or lounging near the pool. Works on wet hair, too!

** Fekkai Pré-Soleil Hair Mist

**And for a little shake-up, here's a mist. Again, it does the whole spectrum of UV torture defense and adds moisture to prevent frizz—just shake up the festive orange bottle to mix and have at it. But there's a bonus—this one adds shine! So, really, it's something you'd want to do anyway. It's almost too much.
