How the score is calculated
  • Actives and evidence0.4Little evidence of effect
  • Completeness for the purpose1.0For “styling hold” — 100 %; a formula with one main purpose
  • Tolerance0.9Debatable ingredient groups: fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • colour-treated hair
  • dry hairthe polymer film itself is not drying, but styling products are almost always alcohol-based, and alcohol is drying
  • sensitive skinirritation possible
  • atopic skinfragrance is a common trigger
Free from:
  • alcohol (alcohol denat) · by the listthe list has no ingredient of the “denatured alcohol” group — evaporates fast and degreases; frequent contact can dry the skin — a tolerance question, not a regulatory one; does not clog pores
  • sulfates (SLS/SLES) · by the listthe list has no ingredient of the “ammonium laureth sulfate (ALES), ammonium lauryl sulfate (ALS), sodium coco-sulfate, sodium laureth sulfate (SLES), sodium lauryl sulfate (SLS), sodium myreth sulfate, TEA-lauryl sulfate” group — a cleansing surfactant from the sulfate family but with an ethoxylated chain: it cleanses more gently than lauryl sulfate. Still not for those looking for a sulfate-free product.
  • formaldehyde releasers · by the listthe list has no ingredient of the “formaldehyde releasers” group — preservatives that slowly release formaldehyde; allowed at low levels but a frequent cause of contact allergy
  • isothiazolinones (MIT/MCI) · by the listthe list has no ingredient of the “isothiazolinone preservatives (MIT/MCI)” group — preservatives; banned in EU leave-on products and limited in rinse-off (0.0015%) — a frequent cause of contact allergy
  • parabens · by the listthe list has no ingredient of the “parabens” group — preservatives; methyl- and ethylparaben are recognised as safe at permitted levels, propyl- and butyl- are limited by the EU to 0.14 %; a frequent buyer question rather than proven harm
  • soap · by the listthe list has no ingredient of the “potassium soap (potassium cocoate), plant soap base (sodium palmate, sodium cocoate), tallow soap base (sodium tallowate)” group — liquid soap: fatty acids boiled with alkali. It cleanses well, but its acidity is around 9-10 against 5 for skin, which is why it often leaves tightness. The product is rinsed off, so the question is tolerance.
  • silicones · by the listthe list has no ingredient of the “silicones” group — form a smooth film and shine; inert and not absorbed — a preference question, not a safety one
  • gelatin in the coating · by the listthe list has no ingredient of the “vegetarian coating” group — a plant-based tablet coating instead of gelatin; it keeps moisture out and makes swallowing easier
  • toning dyes · by the listthe list has no ingredient of the “violet toning dyes” group — direct dyes that settle on the hair surface and cancel the yellow cast of blonde; they wash out in 1–3 washes and leave a lilac tint if left too long; HC Blue 2 and Disperse Violet 1 are known contact allergens of hair dyes
  • tar · by the listthe list has no ingredient of the “wood (birch) tar” group — a traditional remedy for dandruff and itching with a sharp smell; it reduces flaking, but can irritate a sensitive scalp and dries the hair
What for: A style is held by a polymer film dried onto the hair: the more of it, the stronger the hold and the more noticeable the stiffness. A styling product does not treat or nourish — its job ends at the next wash.
When:
  • leave-on
on dry or towel-dried hair before styling; wash out with shampoo
When to expect an effect: hold — as soon as the product dries
What is normal: with too much product the hair sticks together and white flakes can appear when combing

Ingredients — 16 components · 1 works

What works: 1 of 16 ingredients: film-forming styling polymers. A style is held by a polymer film dried onto the hair: the more of it, the stronger the hold and the more noticeable the stiffness. A styling product does not treat or nourish — its job ends at the next wash.

Strengths: completeness for the purpose, tolerance

What lowers the score: actives and evidence: little evidence of effect

Questions: fragrance and its allergens: fragrance — the fragrance and its aromatic components; the EU requires 26 of them to be listed separately — matters to people allergic to fragrance, does not affect how the product works

  • Aqua (Water base: coating, fillers · water — the solvent and base; listed first because there is more of it than anything else; in supplements — part of the capsule shell
  • C12-15 Alkyl Benzoate base: coating, fillers · holds back the growth of bacteria and fungi
  • Petrolatum base: coating, fillers · purified cosmetic-grade petroleum products: form a protective barrier film; safety is established, a preference question; 0–2 of 5 (depends on the raw-material source), cosmetic white oil per DiNardo (2005) is non-comedogenic
  • Cera Alba (Beeswax base: coating, fillers · a thickening wax for balms and creams; rarely clogs pores in leave-on face products
  • Kaolin base: coating, fillers · white clay, absorbs oil in masks and powders; does not clog pores
  • Glyceryl Stearate base: coating, fillers · the basic cream emulsifier (neutral NSE form); the self-emulsifying SE form with added potassium stearate is a separate entry, 3 of 5; does not clog pores
  • Ozokerite base: coating, fillers · makes the product thicker or thinner
  • Ceteareth-25 base: coating, fillers · washes oil and dirt off skin or hair
  • PEG-100 Stearate base: coating, fillers · a highly ethoxylated emulsifier, the usual partner of glyceryl stearate; does not clog pores
  • VP/VA Copolymer works · the active ingredient — what the product is for; form: film-forming polymer
  • Propylene Glycol base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Syhthetic Candelilla Wax base: coating, fillers · a plant wax, a thickener for sticks and balms; does not clog pores
  • Sodium Chloride base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Phenoxyethanol base: coating, fillers · the most widespread cosmetic preservative: it keeps the product sterile. Permitted in the EU up to 1 %, recognised as safe at that level.
  • Decylene Glycol base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • Ethylhexylglycerin base: coating, fillers · a preservative booster and skin-conditioning ingredient: it barely preserves on its own but helps phenoxyethanol work and lowers the amount needed.
  • Parfum (Fragrance questions · the fragrance and its aromatic components; the EU requires 26 of them to be listed separately — matters to people allergic to fragrance, does not affect how the product works

Kapous Studio Professional Matt Wax is a product whose active ingredient is film-forming styling polymers. The concentration is not declared, but the active sits above the 1 % line in the list — a working share is likely. There is little evidence of effect: the polymer dries on the hair as a film and glues the strands to each other — hence the hold. It really can keep a style in humid air: in laboratory measurements a curl keeps 60–70 % of its shape at 85 % relative humidity. But these are measurements on tresses and data from the polymer makers, not trials in people, so the level of evidence is low. The formula has 16 ingredients, 1 of which does the work; the rest is the formula base. Worth noting: Parfum (Fragrance (the fragrance and its aromatic components; the EU requires 26 of them to be listed separately — matters to people allergic to fragrance, does not affect how the product works). A style is held by a polymer film dried onto the hair: the more of it, the stronger the hold and the more noticeable the stiffness. A styling product does not treat or nourish — its job ends at the next wash. By the list, no alcohol (alcohol denat), sulfates (SLS/SLES), formaldehyde releasers, isothiazolinones (MIT/MCI), parabens, soap, silicones, gelatin in the coating, toning dyes, tar. Suitable for: adults, colour-treated hair. dry hair, sensitive skin, atopic skin — ask a doctor. fragrance allergy — not without a doctor. Use: on dry or towel-dried hair before styling; wash out with shampoo. When to expect an effect: hold — as soon as the product dries.
