How the score is calculated
  • Actives and evidence0.8Effect moderately supported
  • 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 broad formula across 3 purposes
  • Cleansing base0.6Harsh surfactants: sodium laureth sulfate (SLES); mild surfactants: cocamidopropyl betaine; irritation potential of the base — 40 % of SLS
  • Tolerance0.6Rinse-off product; debatable groups: benzyl alcohol, cocamide DEA, fragrance and its allergens (skin test positive in 13 of 100 tested)

  • oily skin

  • pregnancyallowed per the leaflet

  • dry scalpmay dry
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
  • morning
  • evening
morning and evening
When to expect an effect: sebum, shine — 2–4 weeks
What is normal: mild dryness

Ingredients — 23 components · 1 works

What works: 1 of 23 ingredients: zinc pca. 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: effect moderately supported; 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.; benzyl alcohol; fragrance and its allergens: fragrance, limonene

  • 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
  • Betula Alba Bark Extract base: coating, fillers · gives taste — in toothpastes and mouth products
  • Juniperus Sibirica Needle Extract base: coating, fillers · draws water in and holds it in the upper layer of the skin
  • Melilotus Albus Flower/Leaf/Stem Extract base: coating, fillers · holds back the growth of bacteria and fungi
  • Lavandula Angustifolia 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
  • Mentha Arvensis 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
  • Usnea Barbata 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
  • 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.
  • 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.
  • Polyquaternium-7 base: coating, fillers · a conditioning polymer: it removes static, makes combing easier and softens the foam.
  • Sodium Chloride base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Zinc PCA works · the active ingredient — what the product is for; form: zinc PCA
  • Benzyl Alcohol questions · a preservative and solvent permitted in the EU up to 1 %. It is also on the list of 26 fragrance allergens that must be declared separately, which matters to people allergic to fragrance.
  • Lactobacillus Ferment Lysate base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
  • Bifida Ferment Lysate base: coating, fillers · skin-microbiome ferments, prebiotics and formula antioxidants
  • Lactococcus Ferment Lysate base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • 1,2-Hexanediol base: coating, fillers · a solvent and humectant with antimicrobial action: it helps the product keep without classic preservatives.
  • 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 %.
  • Potassium Sorbate base: coating, fillers · a mild preservative against mould and yeast: used both in cosmetics and in foods and supplements (E202).
  • Citric Acid base: coating, fillers · acidity regulator
  • 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
  • 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
