FAQs
1. What is the best heat protectant spray?
The best heat protectant depends on your hair type and styling needs. Look for ingredients like silicones, polymers, or proteins to create an effective heat shield. Brands like Color WOW, Kérastase, GHD and Redken offer top-rated options trusted by professionals.
2. Do I apply heat protectant to wet or dry hair?
Most heat protectant sprays are designed for damp, towel-dried hair before blow-drying. Some are also suitable for dry hair before using straighteners or curling wands, check the product instructions for best results.
3. How long should you let heat protectant dry?
Allow your heat protectant to fully absorb and dry, usually 1–3 minutes before using heat tools. This prevents steam damage and ensures the protective barrier is active.
