Heat Protection Spray & Cream NZ | Osmo & Davroe Thermal
Shielding Hair From Straighteners, Curlers and Blow Dryers
Styling tools regularly reach temperatures well above what hair can tolerate without protection, and repeated exposure gradually breaks down the proteins that give hair its strength and shine. Heat protection products work by forming a thin barrier around each strand that slows heat transfer and reduces moisture loss during styling, buying hair time to withstand the tool without sustaining lasting damage.
What is in this collection
This range spans lightweight sprays like Osmo Thermal Defense through to richer balms and potions such as Osmo Blow Out Balm and Blowdry Potion for anyone doing a full blow-dry routine. Davroe's Mini Thermaprotect offers a travel-friendly option, while Osmo's Wonder 10 and Straighten Up round out the range with multi-benefit formulas that combine heat protection with smoothing and frizz control.
Brands in this range
Osmo and Davroe make up this collection, offering everyday heat protection sprays through to more intensive pre-styling treatments for anyone using straighteners, curling irons or blow dryers regularly.

Frequently Asked Questions
Do I really need heat protectant if I only style my hair occasionally?
Even occasional heat styling can cause damage, so a light protectant spray is worthwhile any time heat tools are used.
What temperature does heat damage actually start at?
Hair proteins begin to weaken at temperatures above roughly 150 degrees Celsius, which most straighteners and curling irons regularly exceed.
Should I apply heat protectant to wet or dry hair?
Most sprays are designed for damp hair before blow-drying, while some balms and potions are formulated for use on dry hair before straightening or curling.
Can heat protectant fully prevent damage from styling tools?
It significantly reduces damage but cannot make hair fully heat-proof, so keeping tool temperatures reasonable still matters.
What is the difference between Osmo Thermal Defense and Osmo Blowdry Potion?
Thermal Defense is a lightweight spray suited to quick protection, while Blowdry Potion adds styling benefits like smoothing and volume alongside heat protection.
Can I use heat protectant every day if I style my hair daily?
Yes, these products are formulated for regular use and are an important habit for anyone styling with heat daily.
Will heat protectant weigh my fine hair down?
Lightweight sprays like Osmo Thermal Defense are suited to fine hair, while richer balms are better reserved for thicker or coarser hair types.
Does heat protectant also help with frizz?
Several formulas in this range, including Osmo Wonder 10 and Straighten Up, combine heat protection with frizz control and smoothing benefits.
Is Davroe Mini Thermaprotect suitable for travel?
Yes, it is sized specifically for travel and fits easily into hand luggage for on-the-go styling.
Can heat protectant be used on colour-treated hair?
Yes, and it is especially recommended for coloured hair, as heat styling accelerates colour fade without protection.
How much heat protectant should I use per application?
A small amount evenly distributed through damp or dry hair is usually enough; more is not necessarily better and can leave hair feeling weighed down.
Does heat protectant work with hot tools like hair straighteners at their highest setting?
It reduces damage risk even at high settings, but keeping the tool at the lowest effective temperature for your hair type is still recommended.
Can I use heat protectant spray under a hair dryer with a diffuser attachment?
Yes, heat protectant is beneficial any time heated air or tools contact the hair, including diffuser drying.
Will heat protectant help prevent split ends caused by styling?
It reduces the heat-related stress that contributes to split ends, though existing splits still require trimming.
Is there a difference between heat protection for straightening versus curling?
The core protective function is similar, though some formulas like Osmo Straighten Up are optimised specifically for smoothing during flat-ironing.
Can men use these heat protection products for beard styling with heat tools?
Yes, heat protection is relevant any time heat tools are used on hair, including beard straighteners.
Should I reapply heat protectant if I re-style my hair later in the day?
Yes, if you are using heat tools again, reapplying a light amount of protectant is a good habit.
Does heat protectant expire or lose effectiveness over time?
Like most hair products, it has a shelf life and should be used within the timeframe indicated on packaging for best performance.
Can I use heat protectant on hair extensions or wigs?
Yes, most heat protectant sprays are safe for synthetic-blend and human hair extensions, though checking the specific extension care guidance is recommended.
