Fine hair has one consistent problem with conditioners: the ones rich enough to actually condition also flatten. The more moisturising, the limper the result. REF Stockholm Weightless Volume Conditioner is built specifically for the fine-hair conditioning paradox — a lightweight formula that delivers genuine hydration and detangling without the emollient weight that fine hair can't carry, leaving it naturally fuller, bouncier, and easier to style rather than sleek, heavy, and flat. Rated 4.86 out of 5 by customers — many of them specifically with fine or thinning hair — and the product they keep coming back to.

Weightless Volume Conditioner uses a deliberately lean conditioning base — lighter than a standard conditioner's cationic system by design rather than by accident.

Cetrimonium Chloride is the primary conditioning agent — a shorter-chain quaternary ammonium compound than the Behentrimonium Chloride used in richer conditioners. Cetrimonium Chloride provides effective cuticle-smoothing, slip, and detangling at a lighter deposit weight, making it the correct choice for fine hair where over-conditioning is as much of a problem as under-conditioning. Amodimethicone provides targeted silicone smoothing at damaged cuticle points without the uniform coating of heavier silicone systems. Cetyl Esters provide a silky, light emollient feel without the heaviness of fatty alcohol conditioning bases.

Hydroxyethylcellulose is a natural, water-soluble cellulose polymer that provides the conditioner's body and texture without contributing conditioning weight — it creates a lightweight film on the hair surface that adds structure and combability during application without loading the strand. Calcium Pantothenate — the calcium salt of Vitamin B5 — is the primary moisture-binding active, penetrating the cortex and supporting the hair's internal hydration and elasticity particularly at the root level, where fine hair is most vulnerable to the breakage and thinning that compromises density.

Citrus Paradisi (Organic Grapefruit) Fruit Extract is the Weightless Volume collection hero — rich in Vitamin C, flavonoids, and antioxidants that stimulate the scalp and provide radiant shine to fine hair. REF Stockholm notes that Grapefruit Oil "stimulates the scalp" — supporting a healthier follicle environment that contributes to the revitalising effect the collection is known for. Simmondsia Chinensis (Jojoba) Seed Oil closely mimics the hair's natural sebum — absorbing rapidly and without residue to add elasticity and shine to fine strands. Together, Grapefruit and Jojoba deliver the collection's signature lightweight hydration and shine without surface weight. Helianthus Annuus (Sunflower) Seed Extract carries the REF Colour Preserve System. Hydrolyzed Quinoa provides protein and amino acid reinforcement. Glycerin and Butylene Glycol provide humectant moisture balance. Panthenol provides additional cortex moisture-binding support.

Fragrance: the Weightless Volume collection's fresh, airy character — citrus-forward with warm floral base notes from Limonene and Benzyl Salicylate.

100% vegan. Cruelty-free. Colour-safe.

Metro Vancouver note: Fine hair in coastal humidity picks up atmospheric weight through the day, accelerating the flatness that fine hair is already prone to. A conditioning step that delivers genuine moisture without emollient weight — and that specifically supports scalp health through Grapefruit Extract — is the correct foundation for fine-hair volume routines in Metro Vancouver's damp climate.

Who It's For Fine, thin, or low-density hair of all textures. Particularly effective for hair that becomes flat or heavy after conditioning. Works on colour-treated fine hair — the REF Colour Preserve System protects colour vibrancy. Apply after shampooing, distribute evenly, leave for a short while, and rinse thoroughly. Use the minimum amount needed — start with a small application and build only if required.
