Christophe Robin Cleansing Purifying Scrub With Sea Salt, $52

Apparently, the French were way ahead of us when it comes to taking supergood care of their hair. Parisian brand Christophe Robin is now available on Net-a-Porter, and I'm swooning over the luxe packaging of the Cleansing Purifying Scrub with Sea Salt. It comes out like a paste, making it considerably easy to apply, and lathers right into your scalp. Sea salt exfoliates, soothes and boost circulation. It's also paraben-, silicone- and colorant-free, and designed for sensitive scalps (even those suffering from itchiness post-color appointment).

Since you're making your scalp healthier, you're also making your hair healthier -- just think of all the money you'll save on shine sprays. Like the relationship between your skin and makeup, it's easy to look better with less styling if you have healthy hair to begin with. (Perhaps this is why the French have that whole nonchalant "It"-girl thing down pat).

Aveda Scalp Remedy Dandruff Solution, $28

This spray-on, leave-in treatment contains salicylic acid (yes, the stuff you'd use to treat pimples on your face) to gently get rid of dead skin and other nasty buildup. It also contains clarifying lippia to make sure your scalp is in tip-top, squeaky-clean condition. And, because life is all about balance, it also contains sugar beet extract and rosemary, sage and echinacea to hydrate and soothe the scalp, respectively.
