Fine and thin hair needs a shampoo that cleanses thoroughly without stripping — and builds volume from within the hair shaft rather than just from the foam. REF Stockholm Weightless Volume Shampoo is the Weightless Volume collection's foundation: a sulfate-free formula with a notable triple protein complex and three-oil botanical blend that cleanses gently, reinforces the structural integrity of fine strands, stimulates the scalp with Organic Grapefruit Oil, and leaves hair with the fullness, shine, and touchable body that fine hair looks best with. 4.86 out of 5 across 14 reviews, with customers specifically noting "the hair gets volume" and wonderful results on fine, thinning hair.

Weightless Volume Shampoo uses a gentle sulfate-free surfactant system calibrated to cleanse fine hair without the aggressive stripping that diminishes the natural body and elasticity that fine hair relies on for volume.

Disodium Laureth Sulfosuccinate is the primary surfactant — a mild, fatty alcohol-derived sulfosuccinate that produces a clean, fresh lather without SLS or SLES chemistry. Cocamidopropyl Betaine and Cocamidopropyl Hydroxysultaine are the amphoteric co-surfactants that moderate the cleanse, improve foam quality, and leave the scalp in better condition at rinse-out. PEG-120 Methyl Glucose Dioleate and PEG-60 Hydrogenated Castor Oil provide additional emulsification and a conditioning feel through the rinse.

Polyquaternium-22 and Guar Hydroxypropyltrimonium Chloride are the dual in-wash conditioning polymers — Polyquaternium-22 is a cationic film-former that deposits at damaged cuticle points, reducing static and improving in-shower combability; Guar Hydroxypropyltrimonium Chloride is a cationic guar that provides the slip and anti-static conditioning that makes fine hair more manageable during and after the wash. Both are calibrated to condition without the heavy deposit that would flatten fine hair.

The triple protein complex is the shampoo's most technically sophisticated feature:

Hydrolyzed Vegetable Protein PG-Propyl Silanetriol is a silicone-grafted vegetable protein — it combines the cortex-penetrating reinforcement of hydrolyzed protein with the surface-protective properties of a silicone, creating a deposit that simultaneously strengthens the hair from within and creates a protective surface layer during the wash. Hydrolyzed Soy Protein provides complementary amino acid deposit for breakage prevention and surface strengthening. Hydrolyzed Quinoa delivers the REF Stockholm care signature protein reinforcement. Together the three protein actives address fine hair's primary vulnerability — the tensile weakness that makes each strand prone to breakage and reduces the visible density of thin hair over time.

The three-oil botanical complex provides conditioning and scalp nourishment during the wash:

Prunus Armeniaca (Apricot) Kernel Oil is rich in Oleic (Omega-9) and Linoleic (Omega-6) acids — a lightweight, fast-absorbing emollient with particular affinity for the hair's cuticle surface, adding subtle conditioning and shine at the cleanse step. Simmondsia Chinensis (Jojoba) Seed Oil closely mimics natural sebum — conditioning without residue. Camelina Sativa Seed Oil is the formula's most distinctive oil — derived from Camelina (False Flax), it is exceptionally high in Alpha-Linolenic Acid (Omega-3, typically 30–45%), an essential fatty acid that supports scalp skin barrier health and provides a conditioning profile distinct from the more common Omega-6 oils. It is also rich in Vitamin E, providing antioxidant protection at the scalp level.

Citrus Paradisi (Organic Grapefruit) Fruit Extract is the Weightless Volume collection hero — its Vitamin C, flavonoid, and antioxidant profile stimulates the scalp, provides radiant shine, and carries the REF Colour Preserve System's UV-protective function through the Helianthus Annuus Seed Extract. Hydrogenated Vegetable Oil provides additional lightweight emollient conditioning. Glycerin and Butylene Glycol provide humectant moisture balance.

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

Metro Vancouver note: Fine hair in coastal humidity absorbs atmospheric moisture weight through the day, compounding the flatness that fine hair is already prone to post-styling. A sulfate-free shampoo that deposits protein and scalp-stimulating botanical actives during the cleanse step builds cumulative resilience against the humidity-driven volume loss that affects fine hair most acutely in Metro Vancouver's Pacific climate.*

Who It's For Fine, thin, or low-density hair of all textures. Suitable for everyday use — the sulfate-free formula is gentle enough for daily washing. Works on colour-treated fine hair — the Colour Preserve System protects vibrancy. Apply to wet hair, massage from root to ends, rinse, repeat if needed, and follow with Weightless Volume Conditioner.
