  • 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 base0.6Harsh surfactants: sodium laureth sulfate (SLES); mild surfactants: cocamidopropyl betaine, lauryl glucoside; irritation potential of the base — 37 % of SLS
  • Tolerance0.2Rinse-off product; debatable groups: cocamide DEA, 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)

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
  • 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
  • daytime
  • evening
any time, can be applied often
When to expect an effect: soothing — days; barrier — 2–4 weeks; smoothness — right after use, until the next wash; softness — immediately; barrier — 2–4 weeks; judge shedding no earlier than after 8 weeks
What is normal: with frequent use the hair may feel stiffer; a light film on the skin; no noticeable change in the first weeks

What lowers the score: actives and evidence: actives with strong evidence: 0 of 5; completeness for the purpose: for “hair shedding” — 6 %; 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.; fragrance and its allergens: fragrance; isothiazolinone preservatives (MIT/MCI): methylchloroisothiazolinone, methylisothiazolinone

  • 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.
  • 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.
  • PEG-4 Rapeseedamide base: coating, fillers · coating glazing agent
  • Lauryl Glucoside base: coating, fillers · a sugar surfactant: it cleanses gently and foams lightly, usually paired with betaines.
  • Hydrolyzed Keratin works · the active ingredient — what the product is for; form: keratin hydrolysate
  • PEG-40 Hydrogenated Castor Oil base: coating, fillers · coating glazing agent
  • Panthenol works · the active ingredient — what the product is for; form: panthenol
  • Sodium Chloride base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Simmondsia Chinensis (Jojoba) Seed Oil works · the active ingredient — what the product is for; form: seed oil
  • 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
  • Polyquaternium-10 base: coating, fillers · soften, condition and carry the actives; the backbone of the texture
  • Lecithin base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • 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
  • Citric Acid base: coating, fillers · acidity regulator
  • 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
