How the score is calculated
  • Actives and evidence0.4Actives with strong evidence: 0 of 2
  • Completeness for the purpose0.1For “dandruff and itchy scalp” — 9 %; without salicylic acid, which lifts the flakes; nasturtium extract; could be added without conflict: salicylic acid (bha), nasturtium extract; below threshold: wild ginger extract; a formula with one main purpose
  • Cleansing base0.8Mild surfactants: coco-glucoside, decyl glucoside, disodium cocoamphodiacetate, disodium laureth sulfosuccinate, sodium cocoyl isethionate, mild surfactants and emulsifiers; irritation potential of the base — 19 % of SLS
  • Tolerance0.9Rinse-off product; debatable groups: fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • colour-treated hair
  • pregnancyno studies in pregnancy — discuss with a doctor
  • sensitive scalpcelery is a known food allergen; if you are allergic to it, this product is not for you
  • 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
  • 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: Dandruff is the Malassezia fungus plus accelerated flaking. You need an antifungal active (piroctone olamine, zinc pyrithione, ketoconazole) and a mild cleansing base; results come after 2–4 weeks of regular washing.
When:
  • when washing, rinsed off
when washing the hair, leave on for 2 minutes
When to expect an effect: itching and tightness — 2–4 weeks; dandruff — 4 weeks of regular washing
What is normal: comfort returns sooner than the flaking goes; flaking eases gradually, not from the first wash

Ingredients — 34 components · 2 work

Strengths: tolerance

What lowers the score: actives and evidence: actives with strong evidence: 0 of 2; completeness for the purpose: for “dandruff and itchy scalp” — 9 %; cleansing base: mild surfactants: coco-glucoside, decyl glucoside, disodium cocoamphodiacetate, disodium laureth sulfosuccinate, sodium cocoyl isethionate, mild surfactants and emulsifiers

Questions: fragrance and its allergens: citral, fragrance, limonene, linalool — 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

  • 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
  • DECYL GLUCOSIDE* base: coating, fillers · one of the gentlest cleansing ingredients: a sugar surfactant that barely disturbs the skin barrier.
  • SODIUM COCOYL ISETHIONATE base: coating, fillers · a mild surfactant and the base of syndet bars: it cleanses at a skin-close acidity, unlike soap. The foam is dense and creamy.
  • BUTYLENE GLYCOL* base: coating, fillers · a humectant and solvent: it makes the texture lighter and helps actives spread. Better tolerated than propylene glycol.
  • DISODIUM LAURETH SULFOSUCCINATE base: coating, fillers · a mild anionic surfactant: it foams almost like the sulfates but is tolerated far better. Common in baby products.
  • GLYCERIN* base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • 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.
  • BETAINE* base: coating, fillers · draws water in and holds it in the upper layer of the skin
  • CETEARETH-60 MYRISTYL GLYCOL base: coating, fillers · keeps the water and oil parts from separating
  • ACRYLATES COPOLYMER base: coating, fillers · an ingredient from the European cosmetic ingredient inventory; what exactly it does in this product is not described here yet
  • APIUM GRAVEOLENS (CELERY) SEED EXTRACT (APIUM GRAVEOLENS SEED EXTRACT)* works · the active ingredient — what the product is for; form: celery seed extract
  • CAPRYLIC/CAPRIC TRIGLYCERIDE* base: coating, fillers · a coconut-oil fraction, a light emollient and carrier of actives; does not clog pores
  • CAPRYLYL GLYCOL base: coating, fillers · a humectant that also holds bacteria back, which is why it often replaces part of the preservative.
  • CITRAL* 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
  • CITRIC ACID* base: coating, fillers · acidity regulator
  • COCO-GLUCOSIDE* base: coating, fillers · a sugar surfactant made from coconut oil and glucose: it cleanses gently with modest foam. A common base for baby and sulfate-free shampoos.
  • COCONUT ACID* base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • 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
  • GLYCERYL OLEATE* base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • GLYCOL STEARATE* base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • HELIANTHUS ANNUUS (SUNFLOWER) SEED OIL (HELIANTHUS ANNUUS SEED OIL)* base: coating, fillers · a light emollient oil rich in linoleic acid (in tablets — a coating component); does not clog pores
  • HYDROGENATED VEGETABLE GLYCERIDES CITRATE* base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • LAURETH-3 base: coating, fillers · cleanse and bind water with oils; milder than the sulfate ones
  • LIMONENE* 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
  • LINALOOL* 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
  • MALEIC ACID base: coating, fillers · keeps the acidity of the product within the right range
  • OLETH-10 base: coating, fillers · an ethoxylated emulsifier; the longer the PEG chain across oleth-3, 5, 10, 20, the lower the comedogenicity; rarely clogs pores in leave-on face products
  • POLYQUATERNIUM-22 base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • SODIUM BENZOATE base: coating, fillers · a preservative both in cosmetics and in supplements: a salt of benzoic acid that works in an acidic medium. Permitted as food additive E211 and in cosmetics up to 0.5 %.
  • SODIUM CHLORIDE base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • SODIUM HYDROXIDE* base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • TOCOPHEROL base: coating, fillers · vitamin E at hundredths of a percent: keeps the oils of the formula (a cream or a capsule fill) from going rancid; at that share it protects the product, it is not vitamin E as an active
  • TOCOPHEROL base: coating, fillers · vitamin E at hundredths of a percent: keeps the oils of the formula (a cream or a capsule fill) from going rancid; at that share it protects the product, it is not vitamin E as an active
  • TRISODIUM ETHYLENEDIAMINE DISUCCINATE base: coating, fillers · bind hard-water metals so the formula stays stable and the foam works
  • ZINGIBER ZERUMBET EXTRACT* works · the active ingredient — what the product is for; form: wild ginger extract
