Redken

Why Our Stylists Keep Reaching for Redken

Synergy Hair has stocked Redken for as long as most of our team can remember. Over sixty years of formulation sit behind this brand, and the reason it has lasted that long in professional salons worldwide comes down to something simple: the products do what they say they will. No ambiguity, no overpromising. A Redken shampoo for breakage repairs breakage. A Redken colour range protects colour. The specificity is the point.

What makes Redken hair products different from supermarket alternatives is not just the ingredients – it is how precisely each range is targeted. Rather than broad, do-everything formulas, Redken builds each product line around a single hair concern and engineers the actives at concentrations that actually shift the needle. Bond repair, moisture restoration, colour fade prevention, frizz control, thinning hair treatment, and length retention – each one has its own dedicated range with its own active technology. Nothing tries to be everything at once.

That approach means choosing the right Redken products matters. The wrong range will not harm the hair, but it will not solve the problem either. Here is a guide to each major Redken range, what it does, and who it suits. Our team knows this lineup inside out – get in touch if any of it is unclear, and we will match products to your hair.

Redken All Soft – Dry Hair That Needs Moisture Back

All Soft is the Redken range we pull off the shelf most often in our salons. It suits a wide range of clients: anyone with dry, brittle, or stiff hair that has lost its softness and flexibility. The argan oil base delivers genuine hydration – not a silicone coating that mimics softness – and the effect is noticeable from the first wash. Hair feels smoother, moves better, and looks healthier.

The shampoo and conditioner are designed to work together. Using them together delivers sustained hydration that builds over several washes rather than just a temporary softness that rinses out the next day. For very dry or coarse hair, applying the All Soft Heavy Cream mask once a week helps push moisture deeper into the hair shaft. It is one of the most intensive conditioning treatments in the entire Redken range – thick, rich, and genuinely transformative on hair that regular conditioner is not reaching.

All Soft is colour-safe and gentle enough for daily use. For anyone whose primary complaint is dryness and who wants one Redken shampoo and conditioner pairing to start with, this is usually where we point them.

Redken Extreme – Hair That Breaks and Snaps

Extreme is the repair range. Hair that breaks when brushed, snaps at the mid-lengths, loses elasticity, or feels fundamentally weak – that is what Extreme is built to address. The protein complex in the formula reinforces the strand’s internal structure, reducing breakage and gradually rebuilding the resilience that chemical processing, heat damage, or environmental stress has stripped away.

The shampoo and strengthening conditioner form the base of the routine. For hair that has been bleached specifically, Redken Extreme range targets the more serious structural damage that lightening causes – standard repair formulas do not always reach the level of bond disruption that bleach produces, and this sub-range is formulated for exactly that gap.

Redken Extreme Length is a related range worth knowing about for anyone growing out damaged hair. The frustration of hair that never seems to get past a certain length is almost always a breakage problem – the hair grows at the root, but breaks at the ends at the same rate. Extreme Length supports length retention by strengthening the oldest, most vulnerable sections of the strand, helping them hold on rather than snap off.

Redken Acidic Bonding Concentrate – The All-Rounder

If one Redken range had to be called the starting point for someone who does not know what their hair needs, it would be this one. Acidic Bonding Concentrate – ABC for short – works across all hair types by addressing the foundational health of the strand. It strengthens disrupted bonds, restores the hair’s natural pH balance, and visibly improves condition with consistent use.

ABC comes in several formulations tailored to different hair profiles. The standard range suits hair from normal to damaged. ABC Curls adds curl definition and bounce while also strengthening bonds. ABC Color Gloss combines structural repair with colour vibrancy maintenance. All of them are sulphate-free, which makes them gentle enough for daily washing on chemically treated, coloured, or sensitive hair.

The ABC range also includes a pre-shampoo treatment, a leave-in treatment, and a night-and-day serum for people who want to layer protection around the clock. The leave-in in particular is a strong performer – lightweight, does not weigh the hair down, and adds a noticeable smoothness that lasts through to the next wash. Bundles are available in our store for the shampoo, conditioner, and treatment combination at a better price than buying them individually.

For anyone already using another Redken range for a specific concern – All Soft for moisture, Extreme for breakage, Color Extend for fade – ABC layers underneath as a structural foundation. The two ranges complement rather than compete.

Redken Color Extend – Keeping Colour Where It Belongs

Colour fading between salon visits is one of the most common frustrations we hear. The chemical process that deposits colour into the hair shaft also opens the cuticle, which means colour molecules start escaping the moment the hair is washed. Every shampoo, every heat styling session, every swim in chlorinated water accelerates the fade.

Color Extend Magnetics uses a charged system that physically holds colour molecules inside the strand, slowing the fade and maintaining vibrancy for significantly longer than a standard colour-safe shampoo. The shampoo is sulphate-free and gentle enough for daily use – no harsh detergents stripping colour alongside dirt.

For blondes specifically, Redken Color Extend Blondage uses purple pigment to neutralise brassiness and maintain cool tones between appointments. It performs well as an alternative to other purple shampoos in NZ, particularly for anyone already invested in Redken products and wanting to keep the routine within one brand.

Redken Frizz Dismiss – When Humidity Runs the Show

New Zealand’s climate is not kind to frizz-prone hair. Humidity swings between seasons and sometimes within a single afternoon. Frizz Dismiss is built for exactly this – a sulphate-free range that smooths the cuticle, reduces porosity, and stops the hair from absorbing atmospheric moisture that causes it to puff and misbehave.

The shampoo and conditioner handle the wash-day smoothing. The Frizz Dismiss mask, used once a week, delivers deeper cuticle sealing that holds up through several washes. Finishing products in the range – oils and leave-ins – lock in the smooth finish through the day. For hair that reacts to weather rather than being generally dry or damaged, this is the range to focus on.

Redken Stemoxydine – Thinning Hair at the Follicle Level

Thinning hair and reduced density are concerns that shampoo alone cannot address – the issue is at the scalp and follicle level, not the strand. Redken’s Stemoxydine treatment is a topical serum applied directly to the scalp. The active ingredient stimulates the scalp environment and supports the conditions needed for denser-looking hair growth over time.

It is not instant. Consistent use over several weeks is needed before visible changes appear. But as an accessible, non-prescription option for people noticing reduced density or a thinning part line, Stemoxydine is one of the more credible treatments available – and one we recommend regularly to clients asking about scalp health before resorting to more aggressive interventions.

Redken Brews – Haircare That Men Will Actually Use

Most mass-market men’s shampoo is indistinguishable from body wash in a different bottle. Redken Brews is formulated to the same standards as the rest of the Redken professional range, but is designed specifically for men’s hair textures, scalp concerns, and styling preferences.

The range includes scalp-specific shampoos and conditioners, as well as a full set of styling products. For men dealing with a dry or itchy scalp – which is more common than most will admit – the targeted scalp options in Brews outperform generic men’s shampoos considerably. The styling products provide actual hold and texture control without the crunchy, shellacked finish that cheaper alternatives produce.
