Editor's Pick: If you have fine, soft hair that tends to tangle or get static frizz, this serum has a very lightweight texture that won't leave strands feeling sticky. It works on both dry and wet hair—apply a layer before blow-drying to protect against heat up to 450°F and reduce damage. After application, hair feels smooth and shiny, making it much easier to style in the morning with a sleek, separated look.
