Prevent Heat Damage: 8 Tips That Work
Heat Damage Is Cumulative
Above 300F, keratin proteins undergo permanent structural changes. Damage accumulates over time.
8 Prevention Tips
1. Use heat protectant. Creates thermal barrier. Look for cyclomethicone or dimethicone.
2. Lower temperature. Fine hair needs 250-300F. Thick hair 300-350F. Rarely need above 375F.
3. Dry hair first. Never iron damp hair — water boils inside and fractures the cortex.
4. One pass. Multiple passes multiply damage. Quality tools deliver even heat in one pass.
5. Air dry when possible. Give heat-free days.
6. Deep condition weekly. Replenishes moisture heat strips.
7. Trim every 8-12 weeks. Split ends travel upward.
8. Use ionic tools. Break water molecules faster, reducing heat exposure time.
