Founded in 1997 in Stockholm, Sachajuan crafts its hair-saving products by combining proteins and minerals from sea algae with tailor-made active ingredients. The result? Specialized "recipes" that give hair maximum shine and volume without weighing it down. (Sachajuan calls it ocean silk technology. We call it magic.) This cream protects hair (and hair color) with a built-in UV filter that stays in even after a shower—or a dip in the ocean. It also works as a styling cream, so that's a bonus.
