The ultimate weatherproof shield against frizz. The amika the shield anti-humidity spray is a high-performance, heat-activated stylist essential designed to insulate your hair from atmospheric moisture. This ultra-lightweight, completely invisible mist coats each strand to guarantee up to 24 hours of entirely frizz-free perfection, no matter what your weather app predicts.

Engineered for all hair types and textures—especially smooth blow-dries, bouncy balayage, or straightened styles—this advanced spray works to extend the longevity of your look. It provides a defensive barrier that repels humidity and damp air, ensuring your style remains pristine, glossy, and untouched by static.

Why You’ll Love It:

• 24-Hour Frizz Defence: Forms an impenetrable, breathable matrix around the cuticle to completely lock out external dampness and humidity.
• Extreme Heat Protection: Shields fragile hair fibres from thermal damage caused by straighteners, curlers, and blow-dryers up to 230°C.
• Invisible Weightless Finish: Delivers heavy-duty style protection without leaving any crunchy residue, stickiness, or heavy product build-up.
• UV Ray Shielding: Guards your expensive salon colour against sun-induced fading and atmospheric degradation.
• Enhances Natural Bounce: Formulated to maintain the natural elasticity and movement of your style while delivering maximum smoothness.

The Ingredient Powerhouse:

• Polyquaternium-59: An advanced conditioning polymer that smooths down lifted cuticles, prevents static transfer, and provides a built-in UV filter.
• Sea Buckthorn (Obliphica): amika's signature super-fruit extract packed with Omega-7 and antioxidants to intensely moisturise the hair shaft and boost elasticity.
• Hydrolysed Keratin: Fills in structural gaps along the hair fibre to improve natural moisture retention, smooth surface texture, and add body.

Pro-Tip: To fully unlock the climate-proofing properties of this formula, it must be activated by heat. Mist the spray evenly through damp hair before blow-drying to build internal humidity resistance. For absolute iron-clad protection on texture-prone hair or fresh balayage, section your dry hair and give each section a light final dust immediately before using your straightener or curling wand—this permanently fuses the protective polymers onto the cuticle surface!
