Buying Guide
What to look for in a thermal protection spray
Key factors include maximum heat protection temperature, weight of the formula, presence of conditioning or bond-repair ingredients, and how the product feels on your hair. For fine hair, choose a weightless spray; for thick or damaged hair, look for bond-repair or deeper conditioning benefits.
How to use for best results
Apply evenly to damp hair before heat styling. Focus on mid-lengths to ends, then comb through to distribute. Reapply lightly if you plan extended heat styling or humid conditions to maintain frizz control.
