Will this product protect my hair when I use heat tools?

Yes — the formula provides thermal protection rated up to 450°F (230°C), helping shield strands during blow-drying, straightening and curling. It’s formulated to add a protective layer without leaving hair heavy or greasy, supporting styling while minimizing additional damage.

How should I apply this leave-in for the best results?

Use on towel-dried hair: distribute a small amount through mid-lengths to ends, detangle with a comb or fingers, then style as usual. For damaged or fragile hair, incorporate into your regular routine after shampooing and conditioning to maintain strength and manageability.

• Apply to damp, towel-dried hair before styling
• Focus on mid-lengths and ends where bonds often weaken
• Comb or finger-detangle, then proceed with heat styling or air-dry
