Our Boldplex 6 Hair Serum (B09NDRBTKF) works on a molecular level by repairing hair proteins — penetrating deep into each strand of hair, rebuilding, repairing, and protecting the hair against signs of dryness and damage. Though it protects - it is not made specifically for thermal protection.
However, the BoldUniq Heat Protectant Spray (B094RDG6Q8) does the job they are eyeing! The advanced thermal technology wraps each follicle of hair in a weightless but effective protective layer. This formula shields hair from the effects of heat styling up to 230°C/446°F minimizing the effects of damage and breakages to reveal healthy, strong, and shiny hair.
