Directions
Ingredients
  • Alcohol Denat. Solvents
    Solvent

    A fast-evaporating solvent that helps dissolve ingredients and improve product dry time.

    May suit

    People who use styling products that benefit from quick drying or a lightweight feel.

    Worth knowing

    Its quick evaporation can help reduce residue and support a clean finish in styling formulas. Some may notice it can feel slightly drying in leave-in products depending on hair type.

  • Hydrofluorocarbon 152a Solvents
    Propellant

    Used as a propellant to help dispense aerosol hair products in a fine, even spray.

    May suit

    Those using aerosol styling products like hairsprays or texture mists.

    Worth knowing

    It is a common propellant that evaporates quickly, leaving the intended formula on the hair without residue. Its role is purely functional and it does not provide styling or conditioning benefits on its own.

  • Dimethyl Ether Solvents
    Propellant / solvent

    Dimethyl Ether is commonly used as a propellant and solvent in aerosol hair products.

    May suit

    Those using aerosol styling products such as hairsprays may encounter this ingredient.

    Worth knowing

    It helps deliver fine, even sprays and evaporates quickly after application. Its use relates to product format rather than hair type or concerns.

  • VA/Butyl Maleate/Isobornyl Acrylate Copolymer Thickeners and stabilisers
    Film-forming polymer

    A film-forming polymer that helps provide hold, structure and style retention in hair products.

    May suit

    People looking for enhanced styling performance, hold, or humidity resistance.

    Worth knowing

    It is commonly used in gels, mousses and styling sprays to create lightweight, flexible films on the hair. These polymers are widely used in professional styling products for predictable performance.

  • Isobutane Solvents
    Propellant

    Isobutane is a gas used to propel product out of aerosol haircare packaging.

    May suit

    Useful for those using spray or mousse formats that rely on aerosol delivery.

    Worth knowing

    It helps create a fine, even spray and evaporates quickly after application. It does not remain on the hair in meaningful amounts.

  • Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer Thickeners and stabilisers
    Film-forming styling polymer

    A film-forming polymer that provides hold, shape retention and humidity resistance in styling products.

    May suit

    People looking for longer-lasting style hold or frizz control.

    Worth knowing

    This polymer is commonly used in gels, sprays and creams to help hairstyles stay in place. It forms a light, flexible film that washes out with regular cleansing.

  • Aminomethyl Propanol pH adjusters
    pH adjuster

    Helps adjust and stabilise the pH of haircare formulations.

    May suit

    Those interested in how product pH affects hair and scalp feel may find its presence relevant.

    Worth knowing

    It is commonly used at low levels to help formulas stay effective and consistent. It does not act on the hair directly but supports the overall product performance.

  • Cyclopentasiloxane Silicones
    Slip and shine agent

    A lightweight silicone that spreads product evenly and gives a silky, fast-absorbing feel.

    May suit

    People wanting a light, non-greasy smoothing or shine finish.

    Worth knowing

    Often used in serums and oils for a weightless feel. Some prefer silicone-free options depending on routine.

  • Dimethicone Silicones
    Slip and shine agent

    Smooths the hair surface, adds slip and shine and helps reduce frizz.

    May suit

    Frizz-prone, coarse or dry hair wanting a smooth, glossy finish.

    Worth knowing

    Some people prefer silicone-free formulas, especially for certain curl routines. It is widely used and helpful in many smoothing products.

  • PEG-12 Dimethicone Silicones
    Silicone-based conditioning agent

    A water-dispersible silicone that helps soften hair, add slip and reduce frizz.

    May suit

    People looking for smoother, easier-to-detangle hair without a heavy silicone feel.

    Worth knowing

    Because it is water-dispersible, it tends to rinse out more easily than many traditional silicones. It is commonly used in both rinse-off and leave-in formulas for added manageability.

  • Hydrolyzed Keratin Proteins and amino acids
    Protein

    Helps temporarily support and smooth the hair surface for a stronger feel.

    May suit

    Damaged, chemically treated or fragile hair wanting reinforcement.

    Worth knowing

    Protein routines suit some hair well, while very protein-sensitive hair may prefer balance with moisture.

  • Keratin Proteins and amino acids
    Strengthening protein

    Keratin helps reinforce the hair structure and improve the feel of damaged or weakened strands.

    May suit

    Those with chemically treated, heat‑styled, or fragile hair may find it beneficial.

    Worth knowing

    Keratin used in haircare is typically hydrolysed so it can adhere more easily to the hair surface. It offers cosmetic conditioning benefits rather than permanently altering the internal hair structure.

  • Cystine Bis-PG-Propyl Silanetriol Conditioning agents
    Strengthening conditioning agent

    Helps condition and reinforce the hair fibre for a smoother, stronger feel.

    May suit

    Those looking for support with hair strength, manageability or damage care.

  • Helianthus Annuus (Sunflower) Seed Oil Oils and butters
    Emollient oil

    A plant-derived oil that helps soften and condition the hair and scalp.

    May suit

    Worth knowing

    It is rich in fatty acids that support hair softness without feeling overly heavy. Often used as a carrier oil in both rinse-off and leave-in formulas.

  • Ethylhexyl Methoxycinnamate UV filters
    UV filter

    A UV-absorbing ingredient that helps protect hair and colour from sun-related fading.

    May suit

    Those who spend time outdoors or want to help maintain colour-treated hair.

    Worth knowing

    It is widely used in suncare and some hair products to support protection against UV exposure. In haircare, it mainly helps reduce colour fade rather than providing full sunscreen performance.

  • Panthenol Conditioning agents
    Conditioning agent

    Helps condition, soften and add a smooth, healthy feel to the hair.

    May suit

    Most hair types, especially dry or dull hair.
