How the score is calculated
  • Actives and evidence0.4No proven effect when applied: cinchona bark extract
  • Completeness for the purpose1.0For “hair shedding (topical)” — 100 %; niacinamide (vitamin b3); could be added without conflict: niacinamide (vitamin b3); a narrow formula for one purpose
  • Cleansing base0.6Harsh surfactants: sodium laureth sulfate (SLES); mild surfactants: cocamidopropyl betaine, coco-glucoside; irritation potential of the base — 36 % of SLS
  • Tolerance0.8Rinse-off product; debatable groups: denatured alcohol, fragrance and its allergens (skin test positive in 13 of 100 tested)

Free from:
  • 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: Topical products against shedding work weakly: only minoxidil is proven (a medicine we do not score); among cosmetics rosemary oil has moderate data, caffeine weak. The cause of shedding is found by tests: iron, thyroid, vitamin D.
When:
  • when washing, rinsed off
  • morning
  • evening
morning and evening
When to expect an effect: wrinkles — 8 weeks, a modest effect; puffiness — within an hour, briefly; dark circles — no effect to expect; soothing — days; barrier — 2–4 weeks; do not expect a separate effect from quinine; judge shedding no earlier than after 8 weeks
What is normal: nothing special — well tolerated; losing 50–100 hairs a day is normal with or without any product

Strengths: completeness for the purpose

What lowers the score: actives and evidence: no proven effect when applied: cinchona bark extract; 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; denatured alcohol: alcohol — evaporates fast and degreases; frequent contact can dry the skin — a tolerance question, not a regulatory one; does not clog pores; fragrance and its allergens: fragrance

  • 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
  • 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
  • CINCHONA SUCCIRUBRA BARK EXTRACT* works · the active ingredient — what the product is for; form: cinchona bark extract
  • ADENOSINE* works · the active ingredient — what the product is for; form: adenosine
  • CAFFEINE works · the active ingredient — what the product is for; form: caffeine
  • HYDROLYZED VEGETABLE PROTEIN* base: coating, fillers · proteins cut into short pieces: they settle on hair and skin as a film and make hair smooth and denser to the touch.
  • PANTHENOL works · the active ingredient — what the product is for; form: panthenol
  • ALCOHOL* questions · evaporates fast and degreases; frequent contact can dry the skin — a tolerance question, not a regulatory one; does not clog pores
  • CITRIC ACID* base: coating, fillers · acidity regulator
  • 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
  • GREEN 3 (CI 42053 base: coating, fillers · give the product its colour; do not affect how it works
  • 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
  • PANTOLACTONE base: coating, fillers · draws water in and holds it in the upper layer of the skin
  • POLYQUATERNIUM-10 base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • POLYQUATERNIUM-22 base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • RED 33 (CI 17200 base: coating, fillers · a red colorant of decorative cosmetics; does not clog pores
  • 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 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
