A Leave-In Hair Treatment That Strengthens Your Strands
Redken One United, $34, is like a leave-in conditioner on steroids. It makes hair ridiculously soft and manageable, detangles and strengthens, protects against heat and environmental damage and reduces blow-dry time. Oh, and it controls frizz and static. Basically, there's nothing this spray can't do. It even works as a pick-me-up to limp, already-dry hair.
