Smooth frizz, boost shine, and protect against heat-styling damage with this lightweight leave-in serum. Before spritzing through just-washed hair, shake the bottle to blend the biphase formula. It’s a potent cocktail of strengthening peptides, vitamin C, and the brand’s proprietary ferment, which is made from a superfood blend of roots and mushrooms designed to balance and hydrate the scalp and hair. It works for all hair types and textures, from colored and chemically treated to hair that simply needs help after beach and pool season; the serum is pretty miraculous. (Pro tip: If you have oily hair, apply the serum to your hair and not directly onto your scalp.) 1 fl oz / 30 mL
