Josie Maran

I vehemently recommend Josie's argan oil for any and every cosmetic ailment ever; massaging it into frazzled lengths and ends is just one of them. The pure oil is suitable for hair, but the model and Earth mother has also created a targeted serum for dry strands. It smells divine and doesn't contain alcohol, so it won't (like many "reparative" serums!) actually do more harm than good. [Argan Oil Hair Serum, $30, Sephora]
