Frequently Asked Questions (FAQs)
1. Is heat protectant spray good for hair?
“Heat protectants act as a protective barrier between your hair and a hot tool, protecting it from burning, drying out, and becoming dull. A heat protectant will help smooth the cuticle and leave hair looking shiny and healthy,” explains Chicago-based celebrity hairstylist Alex Brown.
2. Do hair thermal protectants work?
THE BOTTOM LINE. Heat protectants help you reduce heat damage by evening out and slowing how hair heats up. They're only half the solution, however, and can't insulate hair completely, so practice safe styling and remember that there are ways to look cool (or hot) without heat!
3. What does thermal spray do for hair?
Thermal sprays do the same thing for your hair. They form a protective barrier over your hair's cuticle, protecting it from the heat of your hair tools. And just like sunscreen, it also wards off damage caused by UV rays, which can help fight against fade, so your hair color stays fresher longer.
