  • Actives and evidence0.8Effect moderately supported
  • Completeness for the purpose0.4For “oily scalp” — 36 %; rice starch; nettle extract; glycolic acid; could be added without conflict: rice starch, nettle extract, glycolic acid; below threshold: salicylic acid (bha); a broad formula across 6 purposes
  • Cleansing base0.5Harsh surfactants: ammonium lauryl sulfate (ALS), sodium laureth sulfate (SLES); mild surfactants: disodium cocoamphodiacetate; irritation potential of the base — 52 % of SLS

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
  • 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
  • mineral oils and petrolatum · by the listthe list has no ingredient of the “petrolatum and mineral oils” group — 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
  • 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: An oily scalp needs either absorbents (dry shampoo) or sebum-reducing actives (zinc PCA, salicylic acid) and a cleansing base without heavy films.
When:
  • when washing, rinsed off
  • evening
on skin — in the evening, starting 2–3 times a week; in a shampoo — at every wash, leave for 2–3 minutes
When to expect an effect: pores, blackheads — 4–8 weeks
What is normal: mild dryness and flaking in the first weeks

Ingredients — 18 components · 1 works

What works: 1 of 18 ingredients: salicylic acid. An oily scalp needs either absorbents (dry shampoo) or sebum-reducing actives (zinc PCA, salicylic acid) and a cleansing base without heavy films.

Strengths: tolerance

What lowers the score: actives and evidence: effect moderately supported; completeness for the purpose: for “oily scalp” — 36 %; cleansing base: harsh surfactants: ammonium lauryl sulfate, sodium laureth sulfate

Questions: sodium laureth sulfate (SLES): sodium laureth sulfate — the main cleansing surfactant; can dry a sensitive scalp — the reason people look for «sulfate-free»; unrestricted in rinse-off products; ammonium lauryl sulfate (ALS): ammonium lauryl sulfate — a harsh cleansing surfactant, a close relative of SLS: strong foam, but it dries skin and scalp. In rinse-off products this is a tolerance question, not a safety one.; fragrance and its allergens: fragrance, linalyl acetate

  • WATER (AQUA 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
  • SODIUM LAURETH SULFATE questions · the main cleansing surfactant; can dry a sensitive scalp — the reason people look for «sulfate-free»; unrestricted in rinse-off products
  • AMMONIUM LAURYL SULFATE questions · a harsh cleansing surfactant, a close relative of SLS: strong foam, but it dries skin and scalp. In rinse-off products this is a tolerance question, not a safety one.
  • DISODIUM COCOAMPHODIACETATE base: coating, fillers · an amphoteric surfactant of baby and very mild products: it cleanses less strongly than the sulfates and irritates the eyes less.
  • CAPRYLYL GLYCOL base: coating, fillers · a humectant that also holds bacteria back, which is why it often replaces part of the preservative.
  • BENZOIC ACID base: coating, fillers · protect the product from bacteria and mould; used within the EU-permitted concentrations
  • CETEARETH-60 MYRISTYL GLYCOL base: coating, fillers · keeps the water and oil parts from separating
  • CETRIMONIUM CHLORIDE base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • CITRIC ACID base: coating, fillers · acidity regulator
  • DISODIUM EDTA base: coating, fillers · bind hard-water metals so the formula stays stable and the foam works
  • FRAGRANCE (PARFUM 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
  • GREEN 3 (CI 42053 base: coating, fillers · give the product its colour; do not affect how it works
  • HYDROLYZED CERATONIA SILIQUA GUM EXTRACT base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • HYDROXYPROPYL GUAR HYDROXYPROPYLTRIMONIUM CHLORIDE base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • LINALYL ACETATE 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
  • 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.
  • SALICYLIC ACID works · the active ingredient — what the product is for; form: salicylic acid
  • TETRAMETHYL ACETYLOCTAHYDRONAPHTHALENES base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • YELLOW 5 (CI 19140 base: coating, fillers · give the product its colour; do not affect how it works
