HairlustThermal Shield Heat Protectant 150 ml

Silicone-free heat protectant that helps protect against heat damage up to 230°C while fighting frizz and humidity.

Stay on the defensive when it comes to heat. Thermal Shield™ Heat Protectant is a lightweight, silicone-free heat protectant that forms a natural protective film around each strand to help defend against heat styling stress. As a high-performance heat protectant spray, it’s powered by a 100% natural saccharide complex with mushroom extract and hyaluronic acid to help reduce protein loss caused by hot tools and keep your style smooth, glossy and frizz-free.

This silicone-free heat protectant helps protect hair during heat styling up to 230°C and supports long-lasting straight styles, even in humid conditions. If you’re looking for a reliable heat protectant for hair that combines performance and natural ingredients, this formula delivers.

Made with 99.3% natural-origin ingredients and 20.1% organic ingredients. No silicones, drying alcohols, sulfates or parabens.

How it works

Heat styling can weaken the hair fiber by causing protein loss and moisture imbalance. Our advanced heat protection spray for hair forms a lightweight, breathable film on the surface to help absorb part of the heat energy from styling tools, reducing heat accumulation and minimizing damage.

In ingredient testing at 230°C, the active complex showed:

23x more thermal defense vs. placebo

+51% better straightening effect after one flat iron pass

Improved straightening maintenance in 70% humidity for 24 hours

Superior humidity protection compared to silicone benchmarks

This silicone-free heat protectant spray makes styling easier, supports longer-lasting results and reduces the need to repeatedly pass hot tools over your hair. It works as both a daily heat protectant for hair and a protective finishing step before straightening or curling.

Powered by natural performance ingredients, this silicone-free heat protectant combines a mushroom and sugar complex (Polyporus Umbellatus Extract, fructose and sodium hyaluronate) to form a lightweight protective film that helps shield hair from heat stress and humidity. Organic aloe vera and glycerin help maintain moisture balance and softness during styling, while sugar-derived moisturizers support hydration and reduce frizz and flyaways. Organic oat kernel and blueberry extracts help smooth the hair surface and provide antioxidant care. The result is softer, shinier hair with natural movement, without silicone buildup or heaviness.

How to Use:

Shake well and spray root-to-tip onto damp or dry hair before styling. Use Thermal Shield™ Heat Protectant every time before exposing your hair to excessive heat from hair dryers, flat irons or curling irons. This heat protection spray for hair helps ensure even coverage and optimal performance.
