De Lorenzo Defence Extinguish Thermal Protection Spray shields hair from heat while keeping it smooth and soft.
This lightweight spray creates an invisible barrier to help protect your hair from straighteners, curlers, and blow-dryers. It works by coating each strand, helping to reduce moisture loss and visible signs of damage.
The fine mist feels clean, not sticky, and dries quickly with a natural, touchable finish. Hair feels silky, easier to brush, and less frizzy after styling.
Ideal for anyone who uses heat tools regularly, on both coloured and natural hair. Use before every heat styling session to help maintain shine, reduce breakage, and keep ends looking fresher for longer.
A subtle, salon-style scent adds a fresh, just-styled feeling to your routine.
How To Use De Lorenzo Defence Extinguish Thermal Protection Spray
- Shake bottle gently before use.
- Spray evenly onto clean, damp or dry hair from mid-lengths to ends.
- Comb through to distribute, avoiding the roots if hair is fine.
- Style with blow-dryer, straightener, or curler as desired.
- Reapply lightly before using additional heat tools on the same day.
