Living Proof No Frizz Weightless Styling Spray ($37; sephora.com) is a lightweight spray sans silicones and oils that helps block humidity, smooth hair and adds body. Its super lightweight and I use about 2-3 spritzes on damp hair before styling and blow dry as usual. It leaves no residue and adds a lovely, bouncy texture to hair and adds a lot of shine. I have used it while blow drying and air dying and I prefer using it in conjunction with heat since the effects are much nicer and hair feels super sleek and much more manageable. Overall, if you have very fine to normal hair that gets frizzy and need a fabulous heat protectant that is also light weight and won't weight hair down, do give the Living Proof No Frizz Weightless Styling Spray a shot!
