How the score is calculated
  • Actives and evidence0.4No proven effect when applied: biotin (vitamin b7)
  • Completeness for the purpose0.4For “hair shedding (topical)” — 36 %; niacinamide (vitamin b3); could be added without conflict: niacinamide (vitamin b3); below threshold: rosemary oil; a formula with one main purpose
  • Cleansing base0.8Mild surfactants: coco-betaine, coco-glucoside, lauryl glucoside; irritation potential of the base — 24 % of SLS
  • Tolerance0.8Rinse-off product; debatable groups: camphor, fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • childrendo not apply to the face
  • pregnancyan essential oil — ask a doctor
  • atopic skinchildren with atopic skin are sensitised more often
  • sensitive skinpatch test on the inner elbow first
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: 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
any time
When to expect an effect: no effect on growth or shedding should be expected; no visible effect to expect — no data; shedding — 3–6 months
What is normal: a resinous smell, slight tackiness; itching, tingling

Ingredients — 28 components · 3 work

What works: 3 of 28 ingredients: biotin, propolis, rosemary oil. 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.

What lowers the score: actives and evidence: no proven effect when applied: biotin; completeness for the purpose: for “hair shedding” — 36 %; cleansing base: mild surfactants: coco-betaine, coco-glucoside, lauryl glucoside; tolerance: rinse-off product

Questions: camphor: camphor* — a warming and cooling ingredient of rubs. It irritates sensitive skin, and camphor products are not applied to a baby face or chest: the vapour is dangerous for breathing.; fragrance and its allergens: fragrance, hexyl cinnamal, linalyl acetate — 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
  • LAURYL GLUCOSIDE* base: coating, fillers · a sugar surfactant: it cleanses gently and foams lightly, usually paired with betaines.
  • SODIUM COCOYL ALANINATE* label wording · an allergen (sodium (salt)) — matters when limiting salt, for example with blood pressure; the label says it is absent
  • COCO-BETAINE base: coating, fillers · an amphoteric surfactant from coconut oil: it cleanses and stabilises foam. Slightly harsher than cocamidopropyl betaine, yet clearly milder than the sulfates.
  • 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.
  • 1,2-HEXANEDIOL base: coating, fillers · a solvent and humectant with antimicrobial action: it helps the product keep without classic preservatives.
  • ARGININE HCL* base: coating, fillers · amino acids, lipids and sugars akin to the skin’s own components — support for its barrier
  • BENZOIC ACID base: coating, fillers · protect the product from bacteria and mould; used within the EU-permitted concentrations
  • BIOTIN works · the active ingredient — what the product is for; form: biotin
  • CAMPHOR* questions · a warming and cooling ingredient of rubs. It irritates sensitive skin, and camphor products are not applied to a baby face or chest: the vapour is dangerous for breathing.
  • CARAMEL* base: coating, fillers · give the product its colour; do not affect how it works
  • CELLULOSE* base: coating, fillers · filler that gives the tablet its bulk
  • CELLULOSE GUM* base: coating, fillers · a cellulose-based thickener; 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
  • GLYCERIN* base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • GLYCOL DISTEARATE* base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • GREEN 3 (CI 42053 base: coating, fillers · give the product its colour; do not affect how it works
  • HEXYL CINNAMAL* 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
  • 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
  • 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
  • PINENE* base: coating, fillers · stops the product foaming where lather is not wanted
  • PROPANEDIOL* base: coating, fillers · a humectant and solvent from corn sugar: it holds water and helps actives dissolve. A gentler replacement for propylene glycol.
  • PROPOLIS EXTRACT** works · the active ingredient — what the product is for; form: propolis extract
  • ROSMARINUS OFFICINALIS (ROSEMARY) LEAF OIL (ROSMARINUS OFFICINALIS LEAF OIL)* works · the active ingredient — what the product is for; form: rosemary oil
  • 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 CITRATE* 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
