Amika's most concentrated heat defense serum — intensive thermal protection for high-heat tools and colour-treated hair that needs the strongest thermal barrier in the range. The Moda Team Review Blockade is for clients who use high-heat tools and can't afford heat damage on top of everything else their hair is dealing with. Where the Wizard is a light multipurpose pre-style primer, Blockade is a targeted serum specifically formulated for intensive heat protection. The concentration of thermal barrier actives is significantly higher than any spray-format product. A small amount applied to damp hair before heat styling creates a serious protective film around the shaft. Why Moda Carries This Amika was founded in Brooklyn in 2007 and is B-Corp certified, vegan, and cruelty-free. We carry it because our clients ask for it by name — and because it earns its place on performance. The brand has a fun, young energy and a more accessible price point than our core professional lines, without sacrificing results. Perk Up is the dry shampoo we recommend more than any other. The treatment masks — Soulfood, Hydro Rush, The Kure Intense — consistently over-deliver. B-Corp certification aligns with the values we hold as a team and as parents. Key Ingredients Concentrated Heat Defense Complex: High-concentration thermal barrier actives that form an intensive protective film around the hair shaft against heat damage up to 450°F / 230°C. How To Use Apply a small amount to damp hair before heat styling. Distribute through mid-lengths and ends. Do not rinse. Style as usual.
