Why this matters
Frizz isn't one problem — it's moisture swelling the hair cuticle, damage roughening the shaft, or a shampoo that's too stripping for your hair type. New Zealand's coastal humidity makes the first cause common from November through March, especially around Auckland and the Bay of Plenty.
Buying the wrong anti-frizz product wastes money and, more often, wastes the six-to-eight weeks it takes to judge whether a routine actually works. Zilion NZ stocks the full Wella Ultimate Smooth range alongside targeted alternatives, so this guide breaks down which product suits which frizz cause before you commit to a bottle.
What makes the best anti-frizz and shine system
- Cuticle-smoothing ingredients — keratin, amino acids or lightweight oils that lie the hair shaft flat instead of coating it
- Humidity resistance — how well the product holds up in NZ's damp summer air, not just in a dry salon test
- Colour compatibility — sulfate-free or colour-safe formulas that smooth without stripping tone
- Weight on fine hair — smoothing without flattening volume, a common trade-off in richer formulas
- Use frequency — daily shampoo/conditioner systems versus weekly deep treatments serve different routines
- Full-system availability — shampoo, conditioner and treatment sold as a matching range simplifies the routine

1. Wella Professionals Ultimate Smooth: best overall for everyday frizz control
Wella Professionals Ultimate Smooth Shampoo and Conditioner, both sold in 1000ml professional sizes, use a keratin-based formula to smooth the cuticle during the wash, cutting frizz before you even pick up a straightener. It's built for fine-to-medium hair that puffs up rather than hair that's severely damaged or chemically over-processed.
The system works as a daily pair — Wella Professionals Ultimate Smooth Shampoo with Wella Professionals Ultimate Smooth Conditioner — rather than a once-a-week treatment, which suits anyone washing every second day who wants consistent results without adding a step.
Wella Professionals Ultimate Smooth pros:
- Smooths and adds shine in one wash step, no extra treatment required
- Lightweight enough for fine NZ hair that flattens under richer formulas
- Matching shampoo and conditioner pair simplifies the routine
Wella Professionals Ultimate Smooth cons:
- Not strong enough alone for very coarse or tightly curled hair
- Needs fairly consistent use — skipping washes slows results
- No standalone leave-in in the same range for touch-ups between washes
Best for: fine-to-medium NZ hair that frizzes daily but isn't chemically damaged.
Verdict: Buy — the safest default when someone asks about wella ultimate smooth in 2026.
2. Davroe Smooth Anti-Frizz Shampoo: best for humid NZ climates
Davroe Smooth Anti-Frizz Shampoo (1000ml) is built for hair that swells and frizzes the moment humidity climbs, which makes it a better fit than a lighter formula for thick or coarse hair getting through a North Island summer.
Davroe Smooth Anti-Frizz Shampoo pros:
- Targets moisture-triggered frizz specifically, not just general dryness
- Suits thicker, coarser hair textures that overwhelm lighter systems
- Layers well with a leave-in humidity spray on peak humidity days
Davroe Smooth Anti-Frizz Shampoo cons:
- Can feel heavy on fine hair if you use more than a coin-sized amount
- Not a repair treatment for chemically damaged ends
- Best paired with a matching conditioner for full results
Best for: thick or coarse hair that frizzes hard in humid conditions.
Verdict: Buy if humidity, not damage, is your main frizz trigger.
3. Osmo Guardian Angel Anti-Humidity Spray: best leave-in humidity shield
Osmo Guardian Angel Anti-Humidity Spray (250ml) is a leave-in, not a shampoo — it sprays onto dry or damp hair to hold a barrier against humidity through the day, which makes it the product to add on top of whatever shampoo and conditioner you already use.
Osmo Guardian Angel pros:
- Works between washes, extending the life of a smoothing routine
- Fast-drying, no greasy residue for daily styling
- Pairs with any shampoo and conditioner system, including Wella Ultimate Smooth
Osmo Guardian Angel cons:
- Doesn't fix frizz caused by damage or the wrong shampoo
- Needs reapplication on very high-humidity days
- Adds a step some people skip when they're in a hurry
Best for: anyone who wants a quick top-up between full washes.
Verdict: Buy as an add-on, not a stand-alone fix.
4. Wella Professionals Ultimate Repair Mask: best weekly repair treatment
Wella Professionals Ultimate Repair Mask (500ml) targets the structural damage — heat styling, colour, harsh sun — that makes hair frizz because the cuticle is physically roughened, not just dry. It's a once-or-twice-weekly treatment, not a daily conditioner replacement.
Wella Professionals Ultimate Repair Mask pros:
- Concentrated formula addresses damage at the shaft, not just surface frizz
- Noticeable shine boost after a single application on damaged hair
- Works alongside the Ultimate Smooth shampoo for a combined routine
Wella Professionals Ultimate Repair Mask cons:
- Not a substitute for daily shampoo and conditioner
- Overuse on fine, undamaged hair can weigh it down
- Requires planning a weekly treatment slot into your routine
Best for: damaged or over-styled hair where frizz is a symptom of breakage.
Verdict: Buy if your frizz comes with visible split ends or dullness.
5. Pureology Smooth Perfection Shampoo: best for colour-treated hair
Pureology Smooth Perfection Shampoo (1000ml) is sulfate-free, built to smooth frizz without stripping the colour molecules a fresh dye job depends on. It's the pick when hair started frizzing after a colour service, not before it.
Pureology Smooth Perfection pros:
- Sulfate-free formula protects colour vibrancy while smoothing
- Suits colour-treated hair that frizzes at the mid-lengths and ends
- Sits well in a routine with a colour-safe conditioner
Pureology Smooth Perfection cons:
- Premium formula, so it's a bigger spend than a standard shampoo
- Not formulated as a humidity-blocking product on its own
- Best paired with a matching conditioner, sold separately
Best for: colour-treated hair that's started frizzing since the last dye job.
Verdict: Buy for colour-treated hair; skip if you're not colouring.
How this ranking was built
Each product above was measured against the six criteria earlier in this guide — cuticle-smoothing ingredients, humidity resistance, colour compatibility, weight on fine hair, use frequency and whether it's sold as a matching system. Wella Professionals Ultimate Smooth ranks first because it scores well across all six without a major trade-off. The other four earn their spot by solving one specific frizz cause better than a generalist product would.
Which frizz and shine product should you choose?
If you're not sure where to start, buy the Wella Professionals Ultimate Smooth Shampoo and Conditioner pair — it covers the most common NZ frizz complaint, fine-to-medium hair puffing up in humidity, without the trade-offs of a heavier or more specialised formula. Add Davroe Smooth Anti-Frizz Shampoo if your hair is thicker and humidity hits harder, or Pureology Smooth Perfection if frizz showed up after a colour appointment.
Layer Osmo Guardian Angel Anti-Humidity Spray over any of these on the worst humidity days of 2026's summer, and reach for the Wella Ultimate Repair Mask once a week if damage is part of the picture. Zilion NZ carries the full Wella Ultimate Smooth and anti-frizz range, so building a two-or-three-product routine from this list is a single checkout rather than five separate orders.
FAQ
What does Wella Ultimate Smooth do for frizzy hair?
Wella Ultimate Smooth uses a keratin-based shampoo and conditioner system to smooth the hair cuticle during washing, reducing frizz and adding shine without a separate treatment step. It suits fine-to-medium hair that frizzes from everyday humidity rather than chemical damage.
Is Wella Ultimate Smooth good for colour-treated hair?
Wella Ultimate Smooth can be used on colour-treated hair, but Pureology Smooth Perfection Shampoo is the better match if frizz started specifically after a colour service, since its sulfate-free formula protects colour vibrancy while smoothing.
How often should I use an anti-frizz shampoo in NZ humidity?
Most anti-frizz shampoos, including Wella Ultimate Smooth, work best used every wash during humid months, roughly November through March in most of New Zealand. A leave-in spray like Osmo Guardian Angel adds extra protection between washes on the worst days.
What's the difference between Wella Ultimate Smooth and Davroe Smooth Anti-Frizz Shampoo?
Wella Ultimate Smooth is a lighter, everyday formula suited to fine-to-medium hair, while Davroe Smooth Anti-Frizz Shampoo is built for thicker, coarser hair that swells more aggressively in humidity. Pick by hair thickness, not by brand preference.
Can I use Osmo Guardian Angel spray with Wella Ultimate Smooth?
Yes — Osmo Guardian Angel Anti-Humidity Spray is designed to layer over any shampoo and conditioner system, including Wella Ultimate Smooth, as a leave-in top-up between washes.
How much does Wella Ultimate Smooth cost in New Zealand?
Pricing varies by pack size and retailer, so check current pricing on Zilion NZ before you buy rather than relying on an outdated figure.
Does Wella Ultimate Smooth work on curly or coily hair?
Wella Ultimate Smooth is formulated for fine-to-medium hair rather than tightly curled or coily textures; Davroe Smooth Anti-Frizz Shampoo is the better starting point for thicker, more textured hair.
What should I pair with a smoothing shampoo for the best shine?
A weekly treatment like the Wella Professionals Ultimate Repair Mask boosts shine further by repairing the structural damage that dulls hair between washes, on top of whatever daily shampoo and conditioner you use.
One last thing
The most common frizz mistake in NZ bathrooms isn't the product — it's rinsing conditioner in water that's too hot, which reopens the cuticle you just smoothed. Finish the last 10 seconds of every wash with cool water and any of the five systems above performs noticeably better through a humid 2026 summer.
