16 Products That Work Wonders on Dry, Damaged Hair

GuruNanda Rosemary Essential Oil ($6)

My hair always feels significantly smoother after a morning wash when I've slept with rosemary oil on my scalp. While you can also use it on your skin, I love the hair growth benefits that come with dripping it onto my scalp and allowing it to work its magic overnight. I'll often apply this quickly before a morning run, too.
