A mousse applied to dry hair between washes that makes the hair look — in the words of one Swedish customer — better than freshly washed. REF Stockholm Weightless Volume Refreshing Mousse is the product that makes wash day genuinely optional for an extra day or two: a unique award-winning airy mousse that absorbs oil at the roots with Rice Starch, builds volume and shine through the lengths with Grapefruit Extract and a body-building polymer, and leaves no residue, no stickiness, and nothing to rinse out. Not a dry shampoo. Not a volumising mousse. Both — in a single step, applied in seconds on dry hair.

Mechanism Weightless Volume Refreshing Mousse is a leave-in treatment for dry hair that combines three functions — oil absorption, volume building, and conditioning — through a carefully calibrated formula that works on dry strands rather than the wet or damp hair that most mousses require.

Oryza Sativa (Rice) Starch and Distarch Phosphate (a modified, crosslinked rice starch) are the oil-absorbing system. Rice starch particles are fine, transparent, and highly oil-absorbent — physically absorbing scalp sebum and product residue as the mousse is massaged through the roots, leaving no white cast on dark or brunette hair. The crosslinked Distarch Phosphate provides more stable, sustained oil absorption than uncrosslinked rice starch alone, maintaining the fresher-scalp feeling for longer between applications. Magnesium Stearate provides a silky, smooth skin-feel and contributes to the formula's non-sticky, non-residue finish.

Polyquaternium-4 is the volume-building cationic cellulose polymer — the same category of ingredient used in KEVIN.MURPHY BODY.BUILDER and other professional volumising mousses. On dry hair, it coats each strand and equalises the structural charge, reducing static, increasing apparent diameter, and building the body and fullness that makes the hair look volumised and freshly styled rather than limp and day-old. Soytrimonium Chloride provides anti-static conditioning reinforcement. Cetrimonium Chloride and Coco-Betaine add targeted cationic conditioning.

Citrus Paradisi (Organic Grapefruit) Fruit Extract is the Weightless Volume collection hero — the botanical active REF Stockholm has built the entire line around. Grapefruit Extract is exceptionally rich in Vitamin C, flavonoids, and limonene, providing antioxidant protection that shields the hair's structural proteins from the oxidative degradation that progressively reduces volume and body over time. It also contributes to the formula's radiant shine result and the fresh, bright fragrance that makes the post-application experience feel like a genuine hair refresh rather than a styling step. Chenopodium Quinoa Seed Extract delivers the REF Stockholm care signature protein and amino acid reinforcement — here supporting the "anti-breakage system" referenced in the product's own benefits section. Helianthus Annuus Seed Extract carries the REF Colour Preserve System.

Lactic Acid gently lowers the pH to seal the cuticle surface after application, locking in the active deposits. Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate provides antioxidant stabilisation. Ceteareth-60 Myristyl Glycol and Laureth-4 are emulsifiers that help the mousse dispense evenly and distribute through dry hair without clumping. Glycerin, Propylene Glycol, and Butylene Glycol provide humectant moisture balance.

Fragrance: bright citrus-forward signature with floral and warm base notes — limonene, linalool, geraniol, citronellol — consistent with the Weightless Volume collection's fresh, airy character.

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

Metro Vancouver note: Coastal humidity drives accelerated scalp sebum production locally — the warm, damp conditions of Vancouver's Pacific climate can make every-other-day washing feel like a necessity for many customers. The Rice Starch oil absorption and Polyquaternium-4 volume-building in this mousse address both the greasy-root and flat-hair problems simultaneously, making it particularly effective for extending the wash cycle without sacrificing volume in Metro Vancouver's climate.

Who It's For All hair types, particularly fine or thin hair seeking volume and oil absorption on day-two or day-three hair. The leave-in, no-rinse format makes it suitable for use on any wash day schedule. Works on dry hair only — applying to wet or damp hair will reduce the oil-absorption effectiveness and can result in a wet, sticky feel. Apply through dry hair and massage until evenly distributed; do not rinse.

How to Use Apply through dry hair from roots to lengths. Massage until evenly distributed. Do not rinse.

For roots: focus the initial application at the scalp and roots, massaging thoroughly to activate oil absorption. For lengths: work through mid-lengths for volume and body.

Do not apply to wet or damp hair — the formula is calibrated for dry hair application. Applying to damp hair reduces oil-absorption effectiveness.
