VICIOUS Strong Hold Flexible Hairspray

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

• 1 Alcohol Denat. · SD Alcohol 40-B (Alcohol Denat.)
  General function

  Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.

  Role in this product type

  In hairspray, denatured alcohol acts as a fast-evaporating solvent that carries the styling polymers and helps distribute them in a fine spray. As it evaporates, the polymers remain on the hair to form the hold film.

  Leading ingredient

  Listed in the first three ingredients, it is likely a structural part of this formula.

  May suitFine or easily flattened hair

  May suit hair that needs a fast-drying, lightweight spray base rather than an oil- or wax-led finish.

  May not suitDry, coarse, or high-porosity hair

  Porous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.

  DependsVery dry or highly damaged hair

  Consider if hair is very dry or highly damaged: when alcohol is this prominent, the fast-evaporating base may leave the hair feeling drier.

• 2 Hydrofluorocarbon 152a
  General function

  A non-flammable aerosol propellant used in dry shampoos and finishing sprays.

  • propellant
• 3 Isobutane
  General function

  A pressurised gas that pushes an aerosol out of the can and evaporates on contact.

  PubChem
  • propellant
• 4 Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer
  General function

  A firm hold polymer used in hairsprays and gels. It holds well in humidity and brushes out.

  Supporting ingredient

  Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

  May suitClimate-sensitive or frizz-prone hair

  A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

  May suitMaximum-hold styling

  Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

  DependsBuild-up-sensitive routines

  Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.

  • film former
  • polymer
• 5 VA/Crotonates/Vinyl Neodecanoate Copolymer
  General function

  A hairspray polymer that holds firmly and resists humidity.

  Supporting ingredient

  Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

  • film former

• 6 Water · Aqua/Water/Eau
  General function

  The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

  Supporting ingredient

  Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

  • solvent
• ▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
• 7 Aminomethyl Propanol
  General function

  A base used in trace amounts to neutralise acidic hold polymers so they thicken and set properly.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  DependsFrizz-prone, damaged, or high-friction hair

  pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

  PubChem
  • pH adjuster
• 8 Panthenol
  General function

  Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitFine or easily flattened hair

  It hydrates without adding oil or a film, which is the combination fine hair usually needs.

  May suitFrizz-prone, damaged, or high-friction hair

  Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

  May suitVery dry or highly damaged hair

  A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

  PubChem
  • humectant
  • conditioning agent
  • vitamin
• 9 PEG-12 Dimethicone
  General function

  A water-soluble silicone that smooths without the build-up concern of standard silicones.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitBuild-up-sensitive routines

  The PEG- and PPG-modified silicones disperse in water, so ordinary washing carries them off instead of leaving a film to accumulate.

  May suitClimate-sensitive or frizz-prone hair

  A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

  May suitFrizz-prone, damaged, or high-friction hair

  Delivers the slip and surface smoothing of a silicone without needing a detergent wash to remove it afterwards.

  • emollient
  • silicone
  • water-soluble silicone
• 10 Ethylhexyl Methoxycinnamate
  General function

  A UV filter added to protect the product's colour and, in leave-ins, to slow colour fade.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitGray, silver, or brass-prone hair

  Sunlight oxidises hair pigment, and on gray, silver or lightened hair that shows up as yellowing. A UV filter on the label absorbs some of the light that drives it.

  PubChem
  • UV filter
• 11 Fragrance · Parfum/Fragrance
  General function

  An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May not suitFragrance-sensitive routines

  Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

• 12 Citral
  General function

  A lemon-scented fragrance component listed separately as a recognised allergen.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
