Strong hold that you can brush out, restyle, and reshape as many times as you want — without reapplying. That's Reshaper's defining characteristic, and the reason it sits in a different category from Shaper and Shaper Plus+ despite sharing the Sebastian Professional lineup. Where those products use an acrylate hold resin that sets firmly and stays set, Reshaper uses a maleic acid copolymer that delivers strong hold with genuine reworkability — perfect for styles that evolve through the day, midday resets, or anyone who wants serious hold without the commitment of a spray that won't move until you wash it out.

Reshaper's hold system is built around Butyl Ester of PVM/MA Copolymer — a butyl ester of the polyvinylmethyl/maleic acid copolymer. This is a fundamentally different hold resin from the Octylacrylamide copolymer used in the Shaper family. PVM/MA copolymers are known for their multi-blend hold properties: they form a strong film that provides serious shape retention, but the film is softer and more elastic than acrylate-based hold resins — allowing the hair to be brushed through, reshaped, and restyles without the film cracking, flaking, or requiring removal. The hold rebuilds immediately when the hair is re-set. This is the mechanism behind Reshaper's "rework your style, anytime" positioning — the chemistry supports it rather than just claiming it.

Dimethyl Ether serves as the propellant — an ultra-fast-evaporating carrier that delivers the hold resin to the hair surface almost instantaneously, leaving an ultra-dry finish with no wet or sticky feeling at application. This is the mechanism behind the "ultra-dry formula" characteristic that Sebastian highlights: the propellant evaporates before the film fully sets, creating a cleaner, less tacky initial deposit than propellants with slower evaporation rates.

Panthenol (provitamin B5) provides lightweight conditioning within the formula — penetrating the hair shaft and maintaining moisture and elasticity through the hold, preventing the brittleness that strong-hold sprays can cause over repeated use. PEG-12 Dimethicone delivers surface slip and a sateen sheen — the characteristic finish of Reshaper that distinguishes it from a flat, matte strong-hold result. Triethyl Citrate and Glycerin act as film plasticisers and humectants, keeping the polymer film flexible and preventing it from becoming rigid or brittle under the strong-hold deposit. Aminomethyl Propanol adjusts the formula's pH to optimise polymer performance and hold stability.

Ethylhexyl Methoxycinnamate provides UV protection at the hair shaft level — shielding colour-treated hair from the photo-oxidative fade that dulls colour between appointments.

24-hour humidity resistance is Sebastian's own stated claim for Reshaper — the PVM/MA copolymer film resists atmospheric moisture uptake, maintaining the style shape through a full day in damp conditions.

Metro Vancouver note: For styles that need to hold through Metro Vancouver's coastal humidity — and be reshapeable as the day progresses — Reshaper's 24-hour humidity-resistant reworkable hold is the most practical combination in the Sebastian finishing spray range. Use Shaper for everyday touchable hold, Shaper Plus+ where hold needs to be firmer and more fixed, and Reshaper where the priority is strong hold that can be brushed and reset through the day.*

Sebastian Finishing Spray Comparison — Choosing the Right One

All three Sebastian finishing sprays are for all hair types. The difference is hold level and reworkability:

• Shaper → — medium hold, touchable and brushable, everyday styles with natural movement
• Shaper Plus+ → — strong hold, 48-hour humidity resistance, styles that need to stay set through challenging conditions
• Reshaper — strong hold, 24-hour humidity resistance, ultra-dry ultra-reworkable, styles that need to be reshaped and refreshed through the day

Who It's For All hair types and lengths. Particularly effective for styles that are intentionally evolving — multi-stage looks, styles built during blow-drying and refined through the day, or anyone who restyles between morning and evening. Works on damp hair for root-boosting effects, on tousled hair between blow-drying sections to capture movement, and on dry finished styles as the final hold layer. Colour-safe — UV protection makes it appropriate for everyday use on colour-treated hair.

Key Ingredients

• Butyl Ester of PVM/MA Copolymer — Multi-blend hold resin; forms a strong but soft, elastic film that delivers serious shape retention while remaining brushable and reworkable without flaking
• Dimethyl Ether — Ultra-fast-evaporating propellant; delivers an ultra-dry finish with no wet or sticky feel at application
• Panthenol (Provitamin B5) — Penetrates the hair shaft and binds moisture; prevents brittleness and maintains elasticity through the hold
• PEG-12 Dimethicone — Lightweight silicone; provides surface slip and the characteristic sateen finish
• Triethyl Citrate — Film plasticiser; keeps the hold polymer flexible and prevents rigid or brittle set
• Ethylhexyl Methoxycinnamate — UV filter; protects colour-treated hair from photo-oxidative fade

How to Use

Root-boosting: Spray onto damp hair at the root before blow-drying. The hold resin sets as the hair dries, creating lasting root lift.

During blow-drying: Spray onto tousled hair between sections while blow-drying to capture movement and imperfect texture as it sets.

Finishing: Spray lightly over the finished, dry style for long-lasting hold and control.

Midday reset: Brush through the style to release and reshape, then re-set with a light re-spray to rebuild hold.
