How the score is calculated
  • Actives and evidence0.3No proven effect when applied: biotin (vitamin b7)
  • Completeness for the purpose1.0For “dry and damaged hair” — 100 %; without coconut oil — the only oil proven to reduce protein loss; could be added without conflict: coconut oil; a formula with one main purpose
  • Tolerance0.9Rinse-off product; debatable groups: fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • children
  • pregnancytopical — allowed
  • colour-treated hair
  • acne-pronemay clog pores in leave-on face products
  • sensitive skinirritation possible
  • 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.
  • 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: Damaged hair is helped on two fronts: oils that penetrate the shaft (only coconut oil is proven) and a film on the outside — silicones, panthenol, hydrolysed proteins. One from each front is enough; “collagen” and “biotin” in a shampoo work only on the label.
When:
  • when washing, rinsed off
  • morning
any time
When to expect an effect: no effect on growth or shedding should be expected; smoothness — right away, until the next wash

Ingredients — 15 components · 2 work

What works: 2 of 15 ingredients: biotin, collagen. Damaged hair is helped on two fronts: oils that penetrate the shaft (only coconut oil is proven) and a film on the outside — silicones, panthenol, hydrolysed proteins. One from each front is enough; “collagen” and “biotin” in a shampoo work only on the label.

Strengths: completeness for the purpose, tolerance

What lowers the score: actives and evidence: no proven effect when applied: biotin

Questions: fragrance and its allergens: fragrance — 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

  • Aqua/Water/Eau 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
  • Cetearyl Alcohol base: coating, fillers · a fatty-alcohol blend (C16–C18), an emulsifier and thickener, does not dry the skin; paired with ceteareth-20 — 4 of 5; rarely clogs pores in leave-on face products
  • Behentrimonium Chloride base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • Biotin works · the active ingredient — what the product is for; form: biotin
  • Hydrolyzed Collagen works · the active ingredient — what the product is for; form: hydrolysed (type not stated)
  • Dimethicone base: coating, fillers · form a smooth film and shine; inert and not absorbed — a preference question, not a safety one
  • Stearamidopropyl Dimethylamine base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • Isopropyl Myristate base: coating, fillers · emollient/base; may clog pores in leave-on face products
  • Coco-Caprylate/Caprate base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • Steareth-20 base: coating, fillers · an ethoxylated cream emulsifier; rarely clogs pores in leave-on face products
  • Isopropyl Alcohol base: coating, fillers · a volatile solvent alcohol, evaporates without residue; does not clog pores
  • Citric Acid base: coating, fillers · acidity regulator
  • Sodium Hydroxide base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • 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 %.
  • Parfum/Fragrance 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
