Living Proof Full Dry Volume Blast is a featherlight styling spray that delivers a surge of instant volume for big body and texture that'll outlast your plans. The perfect storm for flat hair. Full Dry Volume Blast is powered by Living Proof's patented Volumizing + Texturizing Molecule, which creates big volume by increasing the space between strands. The formula is (almost) as light as air for weightless body and texture that defies midday deflation. Plus, it's made for volume without stiffness - for hair that feels as good as it looks.
