Lock in your look with Hair by Sam McKnight Save the Do Heat Protection Spray, the essential foundation for any flawless blowout. This ultra-light styling mist creates a protective shield that guards against heat damage while smoothing frizz and flyaways for a soft, natural finish. Powered by Flexan and Crodasone, it helps protect hair from drying out and dullness during heat styling, while Pro-Vitamin B5, hibiscus and fire tulip extracts deeply condition and boost shine. Delivering invisible hold, it keeps styles polished and long-lasting without weighing hair down. Finished with Sam’s signature fragrance—created in collaboration with Perfumer H—and housed in recyclable packaging, it’s protection with a luxurious touch.
