Heat protectant goes on before a blow-dryer, flat iron or curling tong: a film of polymers and conditioning agents spreads the heat and reduces moisture loss. Heat Defense has three 250 ml leave-in sprays: REPAIR with keratin for damaged hair, COLOR with a UV filter for coloured hair, SMOOTH against frizz.

## Frequently asked questions

### Do I apply it to wet or dry hair?

To damp hair before blow-drying; again to dry hair before a flat iron. Spray from 20–25 cm along the lengths and comb through.

### Do I need it if I only blow-dry?

Yes — hot air dries the cuticle too. One application on damp hair is enough.

### Will it weigh fine hair down?

The formula is water-based; start with 3–4 sprays and keep it off the roots.
