Heat-styling New Zealanders who reach for a straightener, curling wand or blow-dryer most mornings need one non-negotiable step before the heat touches their hair: a proper pre-heat routine. Davroe Thermaprotect exists for exactly that job, and how you use it before styling matters almost as much as the spray itself.
- Davroe Thermaprotect is a pre-heat spray applied to damp hair before any straightener, wand or dryer touches it.
- Order matters: smoothing shampoo, leave-in treatment, protectant spray, then heat.
- Straighteners commonly run 180-230°C; unprotected hair takes the full hit at those settings.
- Weekly deep conditioning undoes cumulative heat damage a spray alone can't reverse.
- Verdict: buy Davroe Thermaprotect if you heat style more than twice a week; skip it only if hot tools rarely touch your hair.
Why Heat Prep Matters for Frequent Stylers
Hair protein starts to weaken well below the temperatures most straighteners and wands reach, and NZ winters push people toward daily blow-drying just to leave the house with dry hair. That combination is what wears hair down over a few months, not one bad pass with a hot iron.
A smoothing wash routine changes how much heat your hair actually needs. Start with something like Davroe Smooth Anti-Frizz Shampoo 1000ml, which cuts down the frizz and roughness that make people crank the temperature dial higher than necessary in the first place.
The segment this guide is written for isn't occasional stylers touching up for a wedding. It's the daily-straightener, three-times-a-week-curling-wand crowd whose hair is under repeated thermal stress in 2026, week after week.
Why Davroe Thermaprotect Matters Before You Heat Style
Davroe Thermaprotect is built to sit between your hair and the plate, barrel or dryer nozzle, not to replace a wash-day routine. It works as a leave-in step, applied to towel-dried or damp hair before you pick up any hot tool.
Skipping it doesn't just risk split ends. It compounds: hair that takes heat unprotected on Monday is more porous and more heat-reactive by Friday, which means the same straightener setting does more damage the second and third time round.
Wash with a smoothing shampoo before you heat style
The prep starts in the shower, not with the spray bottle.
- Use a sulphate-gentle, smoothing shampoo rather than a clarifying one on styling days
- Rinse with lukewarm rather than hot water to keep the cuticle laying flat
- Skip a second shampoo lather unless your scalp is genuinely oily
- Comb through conditioner with a wide-tooth comb before rinsing to cut down knots
- Avoid vigorous towel-scrubbing; blot and squeeze instead
Apply a lightweight leave-in or treatment while hair is damp
This is the step most people rush or skip entirely, and it's where a treatment earns its place before any heat protectant spray goes on.
- Apply a leave-in treatment through mid-lengths and ends while hair is still damp, not dripping
- Distribute with fingers first, then a wide-tooth comb, to avoid product sitting in one patch
- Keep it off the roots if your hair is fine, to avoid flatness at the crown
- Let it sit for a minute before brushing so it can actually absorb
- A deeper weekly treatment such as Nak Hair Signature Ultimate Treatment works well as the once-a-week version of this step for hair already showing heat wear
Spray Davroe Thermaprotect through mid-lengths and ends
This is the step the whole routine is built around, and it only works if the earlier steps happened first.
- Section hair into two to four parts before spraying so coverage is even, not just on the outer layer
- Hold the bottle 15-20cm away and mist rather than saturate
- Focus on mid-lengths and ends, where the most heat cycles accumulate over a style
- Comb through once more after spraying to spread product before the tool goes near it

Set your tool to the right temperature for your hair type
The protectant does its job better when the tool isn't set higher than your hair actually needs.
- Fine or colour-treated hair: lower end of the typical 180-230°C straightener range
- Thick or coarse hair: upper end of that range, but only after protectant is fully applied
- Curling wands: match barrel heat to hair thickness the same way, not a flat default setting
- Blow-dryers: use a diffuser or lower heat setting on the final pass to seal the cuticle, not just dry the hair
If you can smell heat before you can feel it, the plate is set too hot for that pass.
Section your hair before you straighten or curl
Working in small, deliberate sections beats one fast pass through the whole head.
- Clip hair into four to six sections before starting
- Take pieces no wider than 2-3cm per pass on a straightener
- Never go over the same section more than twice in one styling session
- Keep the tool moving; static heat on one spot is where breakage starts
Finish with a cool shot or a short air-dry pause
The last few minutes of any heat styling session matter more than most people think.
- Use a cool-shot setting on the dryer to close the cuticle after the final pass
- Let curls or straightened sections cool fully before brushing through
- Avoid clipping hair up straight after styling; trapped heat undoes the set
Deep-condition weekly to undo cumulative heat damage
A protectant prevents damage going forward. It doesn't repair what's already happened.
- Book a weekly mask or deep treatment on non-styling days
- Focus product on ends first, where damage shows up earliest
- Alternate a lightweight conditioner on wash days with a heavier mask once a week
- Watch for dullness or excess breakage as a sign to increase treatment frequency
Heat Prep Options Compared
| Option | Best for | Key limitation |
|---|---|---|
| Heat protectant spray (Davroe Thermaprotect) | Daily straightening or curling with lightweight coverage | Needs reapplying after every wash; doesn't reverse existing damage |
| Leave-in treatment or cream | Thick, dry or coarse hair needing extra slip before heat | Can weigh down fine hair if over-applied |
| Smoothing shampoo-and-conditioner routine | Frizz-prone hair that needs prep from the wash step | Not a substitute for a dedicated protectant spray |
| Weekly deep repair mask | Hair already showing heat damage or split ends | Used between styling days, not a same-session pre-heat step |
| Air-drying first, low heat to finish | Anyone cutting total heat exposure time | Slower and impractical before an early start |
Common Mistakes Heat-Styling Kiwis Make
- Spraying protectant on soaking wet hair, which dilutes it and leaves patchy coverage
- Skipping the spray on "just a quick touch-up" days, when repeated small heat hits add up fastest
- Running the same straightener temperature on fine hair as on thick, coarse hair
- Never cleaning tool plates, so residue causes drag and forces extra passes over the same section
- Reaching for whatever shampoo is in the shower instead of a smoothing formula, then blaming the protectant when hair still frizzes
FAQ
What does Davroe Thermaprotect do before heat styling?
It forms a barrier between the hair shaft and a hot tool, applied to damp or towel-dried hair before straightening, curling or blow-drying. It's a leave-in step, not a wash-day product.
How do I apply Davroe Thermaprotect before straightening my hair?
Section damp hair into two to four parts, mist evenly through mid-lengths and ends, then comb through before any heat tool touches it. Even coverage matters more than the amount used.
Can I use a heat protectant on colour-treated hair?
Yes, and it matters more on colour-treated hair since colour processing already leaves the cuticle more porous. Pair it with a colour-safe shampoo and conditioner routine for best results.
What temperature should I set my straightener to?
Most straighteners run 180-230°C, and fine or colour-treated hair should sit at the lower end of that range. Protectant reduces damage but doesn't make higher heat safe for fragile hair.
Do I still need a protectant if I only blow-dry my hair?
Yes. Blow-dryers reach temperatures close to straighteners in the section closest to the nozzle, and daily blow-drying without protection is a common cause of dryness in NZ winters.
How often should I deep-condition if I heat style daily?
Once a week is a reasonable baseline for daily stylers. Increase frequency if ends start looking dull or breakage becomes noticeable between washes.
Is a leave-in treatment the same thing as a heat protectant spray?
No. A leave-in treatment adds moisture and slip before styling, while a dedicated protectant spray is the layer applied right before heat. Frequent stylers usually need both, not one instead of the other.
One Last Thing
The order of operations matters more than the specific products in it. Smoothing wash, leave-in treatment, protectant spray, correct temperature, cool finish, weekly repair mask — skip a step and the ones after it work harder to compensate. Zilion stocks the Davroe range for shoppers building exactly this routine, and Davroe Thermaprotect is the step most people cut first when they're in a hurry, which is exactly why it's the one worth protecting in 2026.
