How the score is calculated
  • Actives and evidence0.6Actives with strong evidence: 1 of 4
  • Completeness for the purpose0.1For “hair shedding (topical)” — 6 %; niacinamide (vitamin b3); could be added without conflict: niacinamide (vitamin b3); below threshold: pea sprout extract; a narrow formula for one purpose
  • Cleansing base0.6Mild surfactants: cocamidopropyl betaine, lauryl glucoside, sodium C14-16 olefin sulfonate, sodium cocoamphoacetate; irritation potential of the base — 36 % of SLS
  • Tolerance0.2Rinse-off product; debatable groups: isothiazolinone preservatives (MIT/MCI) (skin test positive in 6 of 100 tested), isothiazolinone preservatives (MIT/MCI), fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • children
  • colour-treated hair
  • dry skin
  • pregnancyno studies in pregnancy — discuss with a doctor
  • sensitive skinrare contact allergy to impurities
  • atopic skinfragrance is a common trigger
  • 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
  • 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
  • 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
in a mask or conditioner after washing, along the length
When to expect an effect: smoothness — right after use, until the next wash; barrier, dryness — 2–4 weeks; judge shedding no earlier than after 8 weeks
What is normal: with frequent use the hair may feel stiffer; no noticeable change in the first weeks

Ingredients — 27 components · 4 work

What works: 4 of 27 ingredients: hydrolysed keratin, ceramides, pea sprout extract and 1 more. 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: actives with strong evidence: 1 of 4; completeness for the purpose: for “hair shedding” — 6 %; cleansing base: mild surfactants: cocamidopropyl betaine, lauryl glucoside, sodium c14-16 olefin sulfonate, sodium cocoamphoacetate; tolerance: rinse-off product

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; isothiazolinone preservatives (MIT/MCI): methylchloroisothiazolinone, methylisothiazolinone — preservatives; banned in EU leave-on products and limited in rinse-off (0.0015%) — a frequent cause of contact allergy

  • 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 C14-16 Olefin Sulfonate base: coating, fillers · an anionic surfactant often used instead of sulfates: the foam is generous, but among the non-sulfate ones it is the harshest. It may not suit a dry scalp.
  • Sodium Cocoamphoacetate base: coating, fillers · an amphoteric surfactant: gentle cleansing and stable foam, a usual partner to the sugar surfactants.
  • 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.
  • Lauryl Glucoside base: coating, fillers · a sugar surfactant: it cleanses gently and foams lightly, usually paired with betaines.
  • Sorbitol base: coating, fillers · a sugar alcohol: a humectant in cosmetics, a sweetener and filler in supplements. In large amounts by mouth it can loosen the stool.
  • PEG-40 Hydrogenated Castor Oil base: coating, fillers · coating glazing agent
  • Hydrolyzed Keratin works · the active ingredient — what the product is for; form: keratin hydrolysate
  • Chitosan Succinamide base: coating, fillers · leaves a thin film on skin or hair

  • Citric Acid base: coating, fillers · acidity regulator
  • Cetrimonium Chloride base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • 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
  • Crambe Abyssinica Seed Oil base: coating, fillers · the plant base: emollient oils, waxes and care extracts
  • Ceramide NP works · the active ingredient — what the product is for; form: ceramides NP, AP, EOP
  • Hydrogenated Lecithin 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
  • Caprylic/Capric Triglyceride base: coating, fillers · a coconut-oil fraction, a light emollient and carrier of actives; 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.
  • PEG-120 Methyl Glucose Dioleate base: coating, fillers · a thickener for mild cleansers; does not clog pores
  • Methylchloroisothiazolinone questions · preservatives; banned in EU leave-on products and limited in rinse-off (0.0015%) — a frequent cause of contact allergy
  • Methylisothiazolinone questions · preservatives; banned in EU leave-on products and limited in rinse-off (0.0015%) — a frequent cause of contact allergy
  • Pisum Sativum (Pea) Sprout Extract works · the active ingredient — what the product is for; form: sprout extract
  • 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.
  • 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 %.
  • Ocimum Basilicum Hairy Root Culture Extract works · the active ingredient — what the product is for; form: root culture extract
