Buying Guide
What should you look for in a heat protection spray?
- Heat tolerance: Choose a formula that protects up to the highest temperatures you routinely reach (typically 425–450°F).
- Hair type compatibility: Lightweight formulas suit fine hair; richer formulas help thick or coarse hair without weighing it down.
- Additional benefits: Bond repair, frizz control, shine, and conditioning can influence your choice based on stubborn issues.
- Ingredients: Look for silicones for heat sealing, keratin or amino acids for strength, and natural oils for moisture balance.
- Fragrance and sensitivities: If you have a sensitive scalp, consider fragrance-free options or milder scents.
