Using Spray on coloured hair? Pair it with the Colour Save Colour Protect Conditioner. It keeps your colour vibrant longer and adds extra protection between washes.

It forms a shield that absorbs the heat from your dryer or straightener, keeping moisture locked inside your hair instead of evaporating. The result: much easier frizz control and shinier hair after styling.

Panthenol, or provitamin B5, helps by making your hair smoother and easier to comb. This lightweight heat protector is ideal for fine hair because the Spray base won't weigh hair down. Not yet familiar with the Osmo range? This is a great place to start.

Is Osmo Thermal Defense good for damaged bleached hair? Yes, the Spray provides a solid protective base and adds shine to dull or dry-looking hair. Panthenol and film-forming ingredients help smooth the hair fibre.

If your hair needs intense repair, use Spray as part of a good care routine. Combine it with the Deep Moisture Intensive Repair Mask for added nourishment and repair. The Spray protects during styling, while the mask nourishes from within.

Yes. Osmo Heat Protector has been tested to protect up to 230°C, the temperature at which most straighteners and curling irons operate at their highest setting.

The Spray forms a heat-absorbing layer that slows the heat. This means the hair fibre gets less damage. Use it every time you style with heat, even for a quick touch-up.

Yes, Osmo Heat Protector works on both Maniers. Use it on wet hair before blow-drying. On dry hair, Spray apply before using a straightener or curling iron.

Want protection outside of styling? Heat protection against blow-dry and straighteners is the main function, but Spray also guards against UV rays. Handy if you spend lots of time outdoors and your hair is coloured or a bit dry.

It's a great choice if you style often and want a Spray that feels light. Fine hair benefits most, as the light texture won’t weigh it down. It’s also suitable for daily use without leaving hair dull or sticky.

If your hair is very dry or severely damaged and needs intense care, choose a richer heat protector with ceramides or bond-building tech, like Kérastase. Looking for extra hold alongside protection? A heat-protective primer from L'Oréal Professionnel might suit you better. But for daily, lightweight protection without fuss, Osmo Thermal Defense Heat Protector - 250ml is a reliable pick in the hair products category.
