Sometimes you turn your hair oil bottle over and can't even pronounce the first ingredient. If it's a hair oil, shouldn't the first ingredient be . . . oil? With the PhytoSpecific Baobab Oil ($40), you don't have to worry. Castor oil, shea butter, and sunflower oil all make the list. However, the star ingredient is something you've likely never heard of: African baobab oil. It quickly hydrates a dry scalp (which is a primary Winter worry) and gets rid of the itch. I like to use it before I shampoo as a hot oil treatment. Then, I apply one drop to my scalp and ends every night to keep flakes away. It's so light, you don't have to worry about having greasy strands at the end of the week.
