Living Proof Prime Style Extender Review

What We're Sweet On: Hairstyles That Last and Last

Have you ever been astonished by how well primer helps your makeup stay on all day and secretly wished your hair would follow suit? Living Proof has answered that call with its Prime Style Extender ($20), a unique product that you apply before you style. Just like the primer you use under your makeup, Living Proof's primer works alongside whatever styling products are already in your rotation, amplifying their effects. Plus, it saves your hair from your daily heat-blasting blow-dry in two ways: it cuts drying time in half and extends the life of your blowout.

So how does it work? When you heat and dry your hair, hydrogen bonds "set" the style. But environmental factors (read: wind, rain, humidity, and other frizz factories) break down those bonds, causing your hair to fall flat. The Prime Style Extender reinforces those bonds, keeping your hair pristine. I saw it help straight hair hold up against rain, humidity, and hours in a tight topknot; living proof that this stuff works. Pun intended.
