Amika Blockade Heat Defense Serum 1.7 fl oz

What It Is
A lightweight, nutrient-rich serum that provides powerful heat protection while enhancing softness and shine.

What It Does
This multitasking serum defends strands against damage from blow dryers, flat irons, and curling tools—protecting hair from heat styling without weighing it down. Just a few drops create an invisible shield around the cuticle to smooth frizz, reduce breakage, and lock in moisture. The result: a silky, polished finish with renewed softness and healthy-looking shine.
