How the score is calculated
  • Actives and evidence0.6Actives with strong evidence: 1 of 3
  • Completeness for the purpose1.0For “hair shedding (topical)” — 100 %; below threshold: niacinamide (vitamin b3); a narrow formula for one purpose
  • Tolerance0.9Debatable ingredient groups: fragrance and its allergens (skin test positive in 13 of 100 tested)
  • adults
  • pregnancyallowed per the leaflet
  • oily skin
  • acne-prone
  • sensitive skinat 10 % flushing is possible
  • rosaceaask a dermatologist
  • 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.
  • 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
  • evening
into the scalp at night, every day
When to expect an effect: if there is an effect, it shows no earlier than 3–6 months; puffiness — within an hour, briefly; dark circles — no effect to expect; tone, pores — 4–8 weeks; sebum — 2–4
What is normal: hair may look oilier at the roots; mild flushing in the first days at high concentration

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 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
  • Butylene Glycol base: coating, fillers · a humectant and solvent: it makes the texture lighter and helps actives spread. Better tolerated than propylene glycol.
  • PPG-26-Buteth-26 base: coating, fillers · makes hair softer and easier to comb
  • Apigenin base: coating, fillers · keeps the oils in the formula from going rancid
  • Oleanolic Acid base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • Biotinoyl Tripeptide-1 works · the active ingredient — what the product is for; form: biotinoyl tripeptide-1 (Procapil)
  • PEG-40 Hydrogenated Castor Oil base: coating, fillers · coating glazing agent
  • Acetyl Tetrapeptide-3 works · the active ingredient — what the product is for; form: biotinoyl tripeptide-1 (Procapil)
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • Propylene Glycol base: coating, fillers · humectants and solvents — hold water and help actives dissolve
  • Caffeine works · the active ingredient — what the product is for; form: caffeine
  • Niacinamide works · the active ingredient — what the product is for; form: niacinamide
  • Lysine base: coating, fillers · makes hair softer and easier to comb

  • Serine base: coating, fillers · amino acids, lipids and sugars akin to the skin’s own components — support for its barrier
  • Glutamic acid base: coating, fillers · amino acids and PCA — substances the skin itself keeps in the outer layer to hold water; in a product they are humectants copying its own set
  • Proline base: coating, fillers · amino acids, lipids and sugars akin to the skin’s own components — support for its barrier
  • Glycine base: coating, fillers · amino acids, lipids and sugars akin to the skin’s own components — support for its barrier

  • Serenoa Serrulata Fruit Extract base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • Xanthan Gum base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • Triethanolamine base: coating, fillers · a pH adjuster and thickener neutraliser; rarely clogs pores in leave-on face products
  • 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.
  • Ethylhexylglycerin base: coating, fillers · a preservative booster and skin-conditioning ingredient: it barely preserves on its own but helps phenoxyethanol work and lowers the amount needed.
  • 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
