Fine hair has a weight problem. Not its own weight – everything else’s. A conditioner that is slightly too rich, a shampoo with silicone residue, or even mineral buildup from hard water. All of it accumulates on already-thin strands, and by lunchtime, the volume washed into the hair that morning has completely collapsed.
Regular shampoos are not designed to address this. They clean, sure, but they leave behind conditioning agents and coating ingredients that fine hair cannot carry without going flat. A proper volumising shampoo strips all of that away and replaces it with lightweight actives – proteins, amino acids, bodifying polymers – that plump each individual strand without sitting on top of it.
We have stocked these brands at Synergy Hair for over 25 years, and we know what actually works on fine and flat hair versus what just markets well. Here is what we recommend, broken down by what the hair actually needs.
This is the most common complaint we hear, and the fix almost always starts in the shower. The best volumising shampoo for fine hair is one that cleanses completely – no film, no residue, nothing left behind on the strand that could drag it down once it dries.
Redken Volume Injection Shampoo does this as well. The formula is milk-light, rinses totally clean, and uses Redken’s Filloxane bodifying complex to add thickness to each fibre without the coated, crunchy feeling that cheaper volume products leave behind. Joico Joifull Volumising Shampoo is another one that moves fast off the shelf – the lather is rich enough to feel like a proper wash, but the formula is designed to lift fine hair without weighing it down. Both rinse clean, which is half the battle.
Kevin Murphy Plumping Wash takes a slightly different angle, using amino acids and densifying agents to thicken the appearance of individual strands over time. The results build with repeated use rather than being a one-wash effect, which suits people who want gradual, lasting fullness rather than a temporary boost that washes out.
One habit that makes more difference than most people realise: keep conditioner completely off the roots. Mid-lengths to ends only. Anything near the scalp flattens fine hair within hours.
Fine and thin are not the same thing, even though they are constantly lumped together. Fine means each strand has a small diameter. Thin means there are fewer strands per square centimetre of scalp. Plenty of people have both, but some have thick individual strands, while others have just a few, or very fine strands with good density. The shampoo for thin hair that works best depends on the situation at hand.
For thin hair specifically – where the goal is creating the appearance of more hair, not just making existing strands stand up taller – Davines VOLU Shampoo is hard to beat. It builds body from the root and adds a soft bounce that makes the hair look and feel fuller. Gentle enough for daily washing, which matters for thin hair because overwashing with a harsh volumising shampoo strips the scalp and causes irritation that can actually contribute to further thinning over time.
Eleven I Want Body Volume Shampoo works from a different angle. Soy and wheat proteins physically penetrate the hair shaft and thicken it from the inside out, so the volume is structural rather than just surface lift. The effect is cumulative – noticeable after the first wash, more pronounced after a week of use. It is one of the most repurchased products in our fine hair range, and its price point makes it accessible as a daily driver without feeling wasteful.
Fine hair that also runs oily is particularly frustrating. The scalp produces sebum at a normal rate, but fine strands lack the surface area to wick it away from the root. Within half a day, the roots look greasy, the hair lies flat against the scalp, and washing again feels like the only option.
Washing more often is not the answer, though. Overcleansing triggers the scalp to compensate by producing more oil, which accelerates the cycle. The better approach is a volume shampoo for fine hair that handles oil without stripping – something that gets the scalp genuinely clean in one wash, so the second wash of the week can be skipped.
Matrix High Amplify Shampoo fits here. Silicone-free, protein-based, lightweight formula that boosts structure in fine and limp hair without leaving anything behind that attracts or traps oil. Milk Shake Volume Solution Shampoo is another good fit – paraben- and SLES-free, with root lift built into the formula, and a clean enough rinse that the hair does not feel like it needs re-washing the next morning.
On non-wash days, a volumising dry shampoo at the roots absorbs excess oil while adding texture. It is one of the most useful tools for oily, fine hair, and it dramatically extends the time between washes.
Colour processing actually helps fine hair in one respect: it roughens the cuticle slightly, which adds grip and texture that makes styled volume hold longer. But it also weakens the strand, making it more prone to breakage – and breaking strands is the last thing thin or fine hair can afford.
A volumising shampoo for fine hair that has been coloured needs to be sulphate-free or at least very low-sulphate, colour-safe, and light enough to preserve lift. Pureology Pure Volume Shampoo checks every box – colour protection is built into the core of the Pureology range, and the volume formula adds body without any heaviness or residue. For anyone maintaining a colour-treated style on fine hair, it is probably the best shampoo in our range for that specific combination.
Kevin Murphy and Davines both have colour-safe options across their volume lines too. Always follow with a lightweight conditioner – colour-safe, mid-lengths to ends only – to keep the hair hydrated without undoing the root lift.
A shampoo for volume does the groundwork, but the rest of the routine determines whether that volume survives past mid-morning. The products that follow – and how they get applied – matter as much as the wash itself.
After shampooing, apply a lightweight volumising conditioner from mid-lengths to ends. Roots stay bare. On towel-dried hair, work a volumising mousse or root-lift spray into the roots only – this is where all-day hold gets built. Blow-dry with the head tipped forward to direct lift at the root, then finish upright and set the style with cool air.
Non-wash days are where dry shampoo earns its keep. A quick hit at the roots absorbs oil, restores texture, and brings back lift that has settled overnight. For fine hair, the routine on day two and day three is almost more important than wash day, because that is when volume typically falls apart.
Some people also find that a volume powder – Eleven I Want Body Volume Powder is a good one – adds grip and lift at the root on days when even dry shampoo is not enough. A tiny amount rubbed into the root area gives fine hair texture it does not naturally have, and the effect holds surprisingly well through the day.
Every shampoo cleans. A volumising shampoo is engineered to clean and then get out of the way – no coating agents, no heavy conditioning residue, nothing that sits on the strand after rinsing. The best ones deposit lightweight volumising actives in the process: proteins that thicken the fibre, polymers that add body, and amino acids that strengthen the strand so it can hold a style.
The difference is most evident on day two. Hair washed with a regular shampoo or a moisturising formula will have collapsed by then. Hair washed with a proper volume shampoo – paired with the right styling – still has shape, movement, and lift at the root. That staying power is the whole point.
Every volumising shampoo and styling product we stock is genuine, sourced through brand-authorised distributors. We have been NZ-owned and operated for over 25 years, and everything in our range is professional haircare we would use on our own clients.

Redken Volume Injection and Joico Joifull are two of the highest-performing products we carry for fine hair that tends to go flat. Both rinse clean and build noticeable volume from the first wash. For fine hair that also needs thickening, Eleven I Want Body Volume Shampoo uses soy and wheat proteins to physically plump the strand - the results compound over time. The right pick depends on whether the main issue is flatness, thinness, or both.
Not all of them - some contain sulphates that strip colour. Pureology Pure Volume Shampoo is colour-safe by design and delivers solid volume on fine hair. Kevin Murphy and Davines also have colour-compatible options in their volume ranges. Always check the label, and follow with a colour-safe conditioner on the lengths and ends.
Two to three times a week works for most fine hair types. Daily washing is fine if the formula is gentle enough - Davines VOLU and Eleven I Want Body are both mild enough for everyday use. On off days, extend volume with dry shampoo at the roots instead of re-washing.
It is one of the best things for that combination. A silicone-free volumising shampoo like Matrix High Amplify or Milk Shake Volume Solution cleanses the scalp of oil without stripping it, and the lightweight formula keeps fine hair lifted rather than weighed down. Pair it with dry shampoo between washes to manage oil at the root without overwashing.
Volumising shampoo focuses on lift - getting the hair to stand away from the scalp and hold body throughout the day. Thickening shampoo targets the diameter of individual strands, using proteins and polymers to make each fibre physically fuller. Some products do both. For fine hair that is also thin, a formula with thickening proteins - like Eleven I Want Body or Kevin Murphy Body Mass - addresses both the lift and the density issue at once.
It lays the foundation, but holding volume all day usually requires a styling product at the roots after washing - a mousse, a root-lift spray, or a volume powder. The shampoo determines how clean and light the hair starts; the styling product determines how long the volume lasts. Without the styling step, even the best volumising shampoo will lose its effect by midday on very fine hair.
Davines VOLU Shampoo is one of the gentlest volumising formulas we carry - it adds body and fullness without drying the scalp or the hair. Milk Shake Volume Solution is another mild option, free of parabens and SLES, that works well for thin hair that is washed frequently. If dryness is a persistent issue alongside thinness, alternate between a volumising shampoo on some wash days and a hydrating shampoo on others to keep the scalp balanced.
