PhytoPhyto Phytovolume Actif Volumizing Spray

BUY at Birchbox

If you've ever used a volumizing mousse, we don't need to tell you about the ramen-like crunch it can give hair. But this heat-activated formula doesn't have that effect. It contains a combination of wheat proteins and amino acids that plump the diameter of each strand of hair, creating all-over fullness. At the roots, it works to lift the hair and hold it for extra height. And, the best part: Instead of feeling sticky or stiff, your hair just feels like hair.
