Spray-on thermal protectors are used to?

• A. Add shine after styling
• B. Protect hair during thermal services
• C. Detangle hair before washing
• D. Colorize the hair

Answer: (B)

Spray-on thermal protectors work by coating the hair with a protective film that shields the strand from the high heat of styling tools. This barrier helps reduce direct heat contact, minimizes moisture loss, and lessens cuticle damage and breakage during thermal services like blow-drying, curling, or straightening. That protective role is why this product is used during heat styling.

They're not primarily intended to add shine, detangle before washing, or colorize the hair, even though some formulas may offer minor shine or other benefits. The main purpose is to guard the hair against heat-induced damage.
