The ultimate thermal shield and glossy finishing elixir for beautifully protected, high-shine hair. The amika Blockade Heat Defense Serum is a professional-grade, ultra-lightweight thermal protectant engineered to safeguard your strands against aggressive heat styling up to 230°C (450°F). Acting as a weightless, defensive barrier, this multi-tasking serum prevents structural moisture loss and cuticle damage while wrapping your lengths in a luminous, glass-like finish.

Specially optimised for all hair types—and a daily essential for preserving the integrity of fragile, chemically lightened lengths and multi-dimensional balayage—this nutrient-rich serum neutralises frizz and flyaways instantly. It easily combats atmospheric humidity, ensuring your sleek blowouts, beachy waves, and straightened styles stay perfectly aligned, touchably soft, and fiercely protected from daily thermal stress.

Why You’ll Love It:

• 230°C Extreme Thermal Defence: Creates a robust, impenetrable shield that protects delicate hair fibres from the intense, moisture-stripping heat of hair dryers, straighteners, and curling wands.
• Intense Frizz & Humidity Control: Seals the outer hair cuticle completely flat to permanently block out damp air, preventing midday frizz and stubborn static flyaways.
• Mirror-Like Gloss: Illuminates lacklustre lengths with a high-definition, light-reflective shine that enhances the bespoke tones of your balayage or highlights.
• Weightless Hydration: Nourishes the hair matrix deeply without leaving behind a heavy, greasy, or sticky residue that drags down your style.
• Vegan & Clean Formula: Proudly cruelty-free and strictly formulated without harsh sulphates, parabens, phthalates, or artificial colours.

The Ingredient Powerhouse:

• Sea Buckthorn Berry (Obliphica): amika’s signature super-fruit ingredient, naturally packed with Vitamin C, Vitamin A, and vital Omega-7 fatty acids. It deeply nourishes the core, boosts elasticity, and promotes exceptional overall hair health.
• Cyclopentasiloxane: A lightweight, breathable conditioning agent that provides incredible slip, drastically reducing mechanical breakage and snagging during brushing and styling.

Pro-Tip: This serum is a dual-action hero! For foundational thermal protection, apply 2 to 3 pumps through damp, towel-dried hair before blow-drying to lock in internal moisture. To achieve a flawless, salon-grade finish, rub a single drop between your palms and lightly skim it over your fully dried, styled hair to seal down split ends, eliminate flyaways, and amplify brilliant shine!
