How the score is calculated
  • Actives and evidence0.6No proven effect when applied: biotin (vitamin b7)
  • Completeness for the purpose1.0For “oily scalp” — 100 %; rice starch; nettle extract; glycolic acid; could be added without conflict: rice starch, nettle extract, glycolic acid; a formula with one main purpose
  • Cleansing base0.7Harsh surfactants: sodium laureth sulfate (SLES); mild surfactants: cocamidopropyl betaine, coco-glucoside, sodium cocoyl glutamate and related acyl glutamates, mild surfactants and emulsifiers; irritation potential of the base — 33 % of SLS
  • Tolerance0.6Rinse-off product; debatable groups: cocamide DEA, fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • oily skin
  • acne-prone
  • children
  • babies

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; sebum, shine — 2–4 weeks; soothing — days; barrier — 2–4 weeks; no effect on growth or shedding should be expected
What is normal: mild dryness and flaking in the first weeks; mild dryness

Ingredients — 28 components · 4 work

What works: 4 of 28 ingredients: salicylic acid, zinc pca, panthenol and 1 more. An oily scalp needs either absorbents (dry shampoo) or sebum-reducing actives (zinc PCA, salicylic acid) and a cleansing base without heavy films.

Strengths: completeness for the purpose

What lowers the score: actives and evidence: no proven effect when applied: biotin; cleansing base: harsh surfactants: sodium laureth sulfate; tolerance: rinse-off product

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; cocamide DEA — a thickener and foam booster. It is restricted: in the presence of nitrites diethanolamides can form nitrosamines, so the regulator caps secondary amines and forbids nitrosating additives; California lists it under Proposition 65.; fragrance and its allergens: fragrance

  • 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
  • Cocamidopropyl Betaine base: coating, fillers · a mild amphoteric surfactant: it builds dense foam and softens the harsh sulfates next to it. It occasionally causes contact allergy, and the culprit is a manufacturing impurity rather than the ingredient itself.
  • 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.
  • Sodium Chloride base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Propylene Glycol base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • Salicylic Acid works · the active ingredient — what the product is for; form: salicylic acid
  • Arginine base: coating, fillers · amino acids, lipids and sugars akin to the skin’s own components — support for its barrier
  • Zinc PCA works · the active ingredient — what the product is for; form: zinc PCA
  • Panthenol works · the active ingredient — what the product is for; form: panthenol
  • Niacin base: coating, fillers · evens out the skin surface, making it look and feel smoother
  • Biotin works · the active ingredient — what the product is for; form: biotin
  • Rosmarinus Officinalis Leaf Extract base: coating, fillers · the plant base: emollient oils, waxes and care extracts
  • Salvia Officinalis (Sage) Leaf Extract base: coating, fillers · plant and algae extracts and floral waters: flavouring and marketing components — at these shares there is no proven effect on the skin; rare reactions in people allergic to that particular plant
  • Nasturtium Officinale Leaf Extract base: coating, fillers · plant and algae extracts and floral waters: flavouring and marketing components — at these shares there is no proven effect on the skin; rare reactions in people allergic to that particular plant
  • Glyceryl Oleate base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • Laureth-2 base: coating, fillers · cleanse and bind water with oils; milder than the sulfate ones
  • Disodium Cocoyl Glutamate base: coating, fillers · amino-acid surfactants: they cleanse at a skin-close acidity and barely dry. The base of gentle gels and shampoos.
  • Glycol Distearate base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Cocamide DEA questions · a thickener and foam booster. It is restricted: in the presence of nitrites diethanolamides can form nitrosamines, so the regulator caps secondary amines and forbids nitrosating additives; California lists it under Proposition 65.
  • Guar Hydroxypropyltrimonium Chloride base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • 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.
  • 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.
  • Potassium Sorbate base: coating, fillers · a mild preservative against mould and yeast: used both in cosmetics and in foods and supplements (E202).
  • 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 %.
  • Citric Acid base: coating, fillers · acidity regulator
  • Lactic Acid base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • 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
