Heat protection that's silicone-free, lightweight, and leaves hair with shine and workable hold rather than a weighted, product-coated finish. REF Stockholm Heat Protection N°230 is built for daily use on hair that sees hot tools regularly — a water-based protective spray that creates a polymer shield against blow-dryer and styling tool heat up to 230°C / 446°F, while nourishing the hair shaft with Quinoa Seed Extract, Panthenol, and Sunflower Extract. The N°230 tells you exactly what it does: protection to 230 degrees, every day, in two spritzes.

Heat Protection N°230 is a water-based, silicone-free heat protection spray — the absence of silicones is both a formulation choice and a key differentiator from most professional heat protectants that rely on dimethicone or cyclomethicone as their primary thermal barrier.

Sodium Laneth-40 Maleate/Styrene Sulfonate Copolymer is the primary heat-protective film-former — and the most technically sophisticated ingredient in the formula. This is an anionic polymer derived from maleic acid and styrene sulfonate that forms a lightweight, flexible film on the hair shaft when applied. Under heat, the film acts as a thermal buffer — absorbing and distributing the energy from the blow-dryer or styling tool before it can penetrate the cuticle and degrade the hair's structural proteins. The polymer's anionic charge also causes it to deposit specifically at the hair surface rather than building up in the cortex, ensuring protective coverage without weight accumulation. This is the mechanism behind silicone-free heat protection: a polymer shield rather than a silicone coating.

VP/VA Copolymer provides the formula's lightweight hold and additional film-forming structure — setting lightly around the blow-dried or styled hair to give the finished result its workable body and shape retention. At the low concentration in this formula, it contributes hold without stiffness. Alcohol Denat. is the primary fast-drying carrier — evaporating rapidly after application to ensure the heat-protective film has deposited on the hair shaft before the tool is applied, rather than sitting wet under the heat.

Helianthus Annuus (Sunflower) Seed Extract provides UV and environmental antioxidant protection — relevant both during and after styling, when the hair is most exposed to oxidative damage. Betaine is a naturally derived amino acid with exceptional water-binding properties — it acts as a humectant, maintaining moisture balance in the hair shaft through the heat styling process and preventing the dehydration that repeated hot tool use causes. Chenopodium Quinoa Seed Extract delivers protein and amino acid reinforcement at the surface, supporting structural resilience with each use. Panthenol penetrates the cortex and binds moisture structurally — improving elasticity and the hair's ability to recover from the stress of heat styling. Glycerin and Butylene Glycol provide additional humectant support. Quaternium-95 provides anti-static conditioning. Cetrimonium Chloride adds targeted conditioning deposition at cuticle damage points. Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate provides antioxidant stabilisation of the formula itself.

The formula sprays as a fine, even mist on damp or dry hair — no visible residue, no weight, no greasy feel. The lightweight hold activates during blow-drying, leaving hair with body and workable shape rather than just the freshly dried result.

Silicone-free. Paraben-free. Sulfate-free. Vegan.

Metro Vancouver note: Daily blow-drying in Metro Vancouver's coastal humidity is a compounding source of heat damage — the atmospheric moisture the hair absorbs in damp conditions makes the hair shaft more vulnerable to heat penetration than dry-climate hair, as water molecules in the cortex superheat and cause micro-fractures in the keratin structure. A heat protectant that delivers both a thermal barrier (Sodium Laneth-40 Maleate/Styrene Sulfonate Copolymer) and cortex moisture-binding (Panthenol, Betaine) addresses both the surface and structural heat damage mechanisms together.*

Who It's For All hair types and lengths that use any hot styling tool regularly — blow-dryers, diffusers, flat irons, curling irons, or wands. The silicone-free formula is appropriate for fine hair, curly hair (no silicone buildup on porous curl patterns), and any customer who avoids silicone-based products. Spray on damp hair before blow-drying for full protective coverage, or on dry hair before flat ironing or curling.

Key Ingredients

• Sodium Laneth-40 Maleate/Styrene Sulfonate Copolymer — Anionic heat-protective film-former; creates a lightweight polymer thermal barrier on the hair shaft that absorbs and distributes heat up to 230°C without silicones
• VP/VA Copolymer — Lightweight hold polymer; provides workable body and shape retention in the finished style
• Betaine — Amino acid humectant; maintains moisture balance in the hair shaft through the heat styling process
• Panthenol (Provitamin B5) — Penetrates the cortex and binds moisture structurally; improves elasticity and heat damage recovery
• Helianthus Annuus (Sunflower) Seed Extract — UV and environmental antioxidant protection during and after styling
• Chenopodium Quinoa Seed Extract — Protein and amino acid reinforcement at the surface; builds structural resilience with regular use
• Glycerin — Humectant; maintains surface moisture balance

How to Use Spray evenly onto damp or dry hair before using a blow-dryer, flat iron, curling iron, or any hot styling tool. Do not rinse. Use blow-dryer or hot styling tool as desired. Apply before every heat styling session for cumulative protection.
