Amika Blockade Heat Defense Serum

A light nourishing oil used prior to using heat tools on hair.

Key benefits:
• Protects against heat
• Prevents moisture loss
• Adds shine

Blockade heat defense serum shields hair from heat styling and blow-drying, protecting against overheating and damage to the delicate hair fiber. The nutrient-packed elixir forms a protective, humidity-proof layer around each hair which prevents moisture loss and ensures a frizz-free, smooth, and shiny finish. The lightweight formulation contains dimethicone to protect against thermal treatments, prevent moisture loss, and form a barrier on the hair that smooths down the cuticle, as well as vitamin-rich sea buckthorn berry to keep hair healthy-looking.
