Those still doubting the magical powers of hair oil might be convinced by Alterna’s Bamboo Smooth Kendi Pure Treatment Oil. Derived from the kendi nut (not harvested, but picked from the ground—hello, sustainability!), it’s packed with essential fatty acids, and just one drop in damp hair can truly transform a dull mane. $24; sephora.com.
