Formulation & Technique
Mastering Texture, Timing and Placement
The Physics of Thermal Denaturation & 'Bubble Hair'
When hot irons exceed 300°F on unprotected damp hair, trapped water within the hair cortex instantly vaporizes, creating microscopic gas bubbles that fracture the hair shaft from the inside out (clinically known as 'bubble hair').
Advanced heat protectant polymers have lower thermal conductivity than water. They form a sacrificial thermal sheath around each strand, diffusing heat evenly and slowing temperature rise so moisture evaporates safely without boiling.
The Dry-Before-Iron Rule
Never touch a flat iron or curling wand to hair that is visibly damp from heat protectant mist. Hearing a 'sizzle' is the sound of hair cuticles burning.
Mist your protectant evenly, wait 60 seconds or run a quick blast of cool air with a blow dryer to evaporate the water carrier, and only iron dry strands.
