How the score is calculated
  • Actives and evidence0.3No proven effect when applied: biotin (vitamin b7)
  • Completeness for the purpose0.5For “hair shedding (topical)” — 53 %; niacinamide (vitamin b3); could be added without conflict: niacinamide (vitamin b3); a broad formula across 3 purposes
  • Tolerance0.8Debatable ingredient groups: formaldehyde releasers (skin test positive in 8 of 100 tested), iodopropynyl butylcarbamate (IPBC), fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • pregnancytopical, in a rinse-off product — allowed
  • colour-treated hair
  • children
  • 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.
  • 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:
  • leave-on
in a leave-in lotion on the roots once a day
When to expect an effect: judge shedding no earlier than after 2 months; smoothness — right after use, until the next wash; puffiness — within an hour, briefly; dark circles — no effect to expect; smoothness — right away, until the next wash; no effect on growth or shedding should be expected
What is normal: with frequent use the hair may feel stiffer

What lowers the score: actives and evidence: no proven effect when applied: biotin; completeness for the purpose: for “hair shedding” — 53 %; tolerance: debatable ingredient groups: formaldehyde releasers, iodopropynyl butylcarbamate, fragrance and its allergens

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; formaldehyde releasers: diazolidinyl urea — preservatives that slowly release formaldehyde; allowed at low levels but a frequent cause of contact allergy; iodopropynyl butylcarbamate (IPBC): iodopropynyl butylcarbamate

  • Lepidium Meyenii (Maca) Root Extract works · the active ingredient — what the product is for; form: maca root extract
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores

  • Hydrolyzed Keratin works · the active ingredient — what the product is for; form: keratin hydrolysate
  • Caffeine works · the active ingredient — what the product is for; form: caffeine

  • Retinyl Palmitate base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • 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
  • Citric Acid base: coating, fillers · acidity regulator
  • Diazolidinyl Urea questions · preservatives that slowly release formaldehyde; allowed at low levels but a frequent cause of contact allergy
  • Iodopropynyl Butylcarbamate questions · a strong antifungal preservative restricted by the regulator: hundredths of a percent at most, banned in oral products and in leave-on products for children under three. A known contact allergen.
  • Propylene Glycol base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Disodium EDTA base: coating, fillers · bind hard-water metals so the formula stays stable and the foam works
  • Biotin works · the active ingredient — what the product is for; form: biotin
