A concentrated heat defense serum that provides intensive thermal protection against heat styling damage — for high-heat tools and colour-treated hair that needs the strongest protection available.
What It Is
Blockade Heat Defense Serum is Amika’s most concentrated heat protection formula. Where the Wizard is a lightweight primer suited for everyday heat styling, Blockade is a serum-format intensive protectant for those using high-heat tools (450°F+), those with colour-treated or damaged hair that can’t afford heat damage, or those who want the strongest thermal barrier available in the Amika range.
