Hair is composed of keratin proteins, and when exposed to high temperatures, these proteins begin to degrade. Water molecules inside the hair expand when heated, creating pressure that causes the cuticle to lift.
The Science of Thermal Defense: How Silicones and Oils Protect Hair from Heat Damage
Silicones and Polymers Dimethicone: Forms a barrier that reflects heat and prevents moisture loss. Effective products are formulated with ingredients that deposit a thermal shield, slowing down the transfer of heat and preserving the integrity of the cortex.
This thermal stress breaks the hydrogen bonds that give hair its shape, leaving it porous and prone to damage. Jojoba Oil: Mimics the natural sebum of the scalp, providing hydration without weight.
How Thermal Defense Science Protects Hair Proteins and Cuticles
Look for products containing dimethicone or cyclomethicone, which create a slick, protective layer on the hair surface. Without the right protection, this cycle of heating and drying leads to brittleness, split ends, and a dull appearance that no amount of styling can fix.
