Dry, coarse, or environmentally stressed hair needs more than a daily conditioner — it needs a treatment that delivers concentrated hydration, smooths the cuticle, restores elasticity, and tames frizz in a single 5–10 minute application. REF Stockholm Intense Hydrate Masque is the Intense Hydrate collection's deepest-treatment product: a rich, reformulated formula with less water and a higher concentration of active ingredients, built around Organic Coconut Oil and a precision silicone conditioning system that leaves hair noticeably softer, smoother, and more manageable after just one use.

Intense Hydrate Masque uses a high-performance conditioning base enriched with targeted actives — formulated with "less water" than the previous version, meaning a higher concentration of every active ingredient per application.

Behentrimonium Chloride is the primary cationic conditioning agent — a fatty acid-derived quaternary that deposits specifically at points of cuticle damage and charge imbalance, delivering targeted slip, detangling, and smoothing precisely where the hair needs it most. On dry or coarse hair where the cuticle is roughened and the negative charge differential is highest, Behentrimonium Chloride deposition is proportionally greater — the more damaged the hair, the more the formula is drawn to treat it.

Bis-Cetearyl Amodimethicone is the masque's most powerful smoothing active — a crosslinked form of Amodimethicone that deposits at damaged cuticle points in a more durable, three-dimensional pattern than standard Amodimethicone. The crosslinked structure creates a stronger, more tenacious bond to the cuticle surface, delivering more lasting smoothing and frizz resistance than a linear silicone can provide. Dimethicone provides the complementary surface-filling and shine-enhancing action across the full hair shaft.

Cocos Nucifera (Organic Coconut) Oil — the Intense Hydrate collection hero — penetrates the hair shaft to prevent protein loss and deliver deep moisturisation, particularly effective for high-porosity and coarse hair where the cuticle's gaps allow moisture to escape rapidly. Cetrimonium Chloride provides additional targeted cationic conditioning at the cuticle surface. Cetearyl Alcohol and Cetyl Alcohol form the rich, creamy emollient conditioning base.

Glycerin and Dipropylene Glycol provide the formula's humectant moisture-binding — drawing water into the hair shaft and maintaining hydration long after rinsing. Butylene Glycol and Propanediol provide additional penetration support and humectancy.

Lactic Acid performs a critical finishing function — it gently acidifies the formula to seal the cuticle at the end of the treatment process, locking in the conditioning complex deposited during the 5–10 minute processing time. Citric Acid reinforces this pH-sealing action. Together they ensure the treatment's benefits are sealed into the hair shaft at rinse-out rather than partially washing away.

Chenopodium Quinoa Seed Extract delivers the REF Stockholm care signature protein and amino acid reinforcement. Helianthus Annuus (Sunflower) Seed Extract provides UV and antioxidant protection including the REF Colour Preserve System. Quaternium-95 provides anti-static conditioning. Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate provides antioxidant stabilisation.

Fragrance: Citrus Limon Peel Oil, Tetramethyl Acetyloctahydronaphthalenes, Alpha-Isomethyl Ionone — a clean citrus-woody-musky profile, consistent with the Intense Hydrate collection signature.

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

Metro Vancouver note: Hard water mineral deposits on the cuticle surface physically block the cationic conditioning agents in a masque from depositing fully — reducing the treatment's effectiveness on hair with active mineral buildup. If results are less than expected on first use, a chelation step before your masque session may significantly improve uptake. See our Hard Water Hair Damage hub for the protocol.

Who It's For Dry, coarse, or thirsty hair of any texture — particularly effective for hair dealing with dryness from environmental stress, chemical treatments, or heat styling. Works across fine, medium, and thick hair types. The reformulated richer formula makes it particularly suitable for very dry or structurally compromised hair that needs more than a standard weekly mask. Use in place of conditioner for a deeper treatment, or follow with REF Intense Hydrate Conditioner for maximum hydration and slip.

Key Ingredients

• Behentrimonium Chloride — Fatty acid-derived cationic conditioning agent; deposits at damaged cuticle points for targeted slip, detangling, and smoothing — treatment response proportional to degree of damage
• Bis-Cetearyl Amodimethicone — Crosslinked Amodimethicone; three-dimensional deposit at damaged cuticle for more durable, lasting smoothing and frizz resistance than standard silicones
• Cocos Nucifera (Organic Coconut) Oil — Penetrating emollient; prevents protein loss and delivers deep moisturisation, particularly effective for high-porosity and coarse hair
• Dimethicone — Surface-filling silicone; fills cuticle micro-gaps for shine and smooth surface feel
• Lactic Acid & Citric Acid — pH-sealing agents; close the cuticle at rinse-out to lock in the deposited conditioning complex
• Glycerin & Dipropylene Glycol — Humectants; draw water into the hair shaft and maintain hydration after rinsing
• Chenopodium Quinoa Seed Extract — Protein and amino acid reinforcement at the hair surface

How to Use Apply to washed, towel-dried hair. Leave on for 5–10 minutes — 5 minutes for regular maintenance, 10 minutes for very dry or damaged hair. Rinse thoroughly. Finish with REF Intense Hydrate Conditioner for additional slip and detangling.
