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.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWeightless 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDisodium Laureth Sulfosuccinate\u003c\/strong\u003e is the primary surfactant — a mild, fatty alcohol-derived sulfosuccinate that produces a clean, fresh lather without SLS or SLES chemistry. \u003cstrong\u003eCocamidopropyl Betaine\u003c\/strong\u003e and \u003cstrong\u003eCocamidopropyl Hydroxysultaine\u003c\/strong\u003e are the amphoteric co-surfactants that moderate the cleanse, improve foam quality, and leave the scalp in better condition at rinse-out. \u003cstrong\u003ePEG-120 Methyl Glucose Dioleate\u003c\/strong\u003e and \u003cstrong\u003ePEG-60 Hydrogenated Castor Oil\u003c\/strong\u003e provide additional emulsification and a conditioning feel through the rinse.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePolyquaternium-22\u003c\/strong\u003e and \u003cstrong\u003eGuar Hydroxypropyltrimonium Chloride\u003c\/strong\u003e 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.
