How the score is calculated
  • Actives and evidence0.9Actives with strong evidence: 3 of 6
  • Completeness for the purpose0.5For “oily scalp” — 48 %; rice starch; nettle extract; could be added without conflict: rice starch, nettle extract; below threshold: salicylic acid (bha), lactic acid; a broad formula across 3 purposes
  • Cleansing base0.8Mild surfactants: decyl glucoside, mild surfactants and emulsifiers; irritation potential of the base — 15 % of SLS
  • Tolerance0.6Rinse-off product; debatable groups: hexyl nicotinate, fragrance and its allergens (skin test positive in 13 of 100 tested); use together with care: glycolic acid + lactic acid, glycolic acid + salicylic acid (bha), niacinamide (vitamin b3) + glycolic acid

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: An oily scalp needs either absorbents (dry shampoo) or sebum-reducing actives (zinc PCA, salicylic acid) and a cleansing base without heavy films.
When:
  • when washing, rinsed off
  • evening
in the evening, 2–3 times a week; SPF in the daytime
When to expect an effect: smoothness — 2–4 weeks; texture, glow — 2–4 weeks; pores, blackheads — 4–8 weeks; hydration — immediately; lasting effect — 2–4 weeks; tone, pores — 4–8 weeks; sebum — 2–4; soothing — days; barrier — 2–4 weeks
What is normal: mild tingling; tingling for 1–2 minutes after applying; mild dryness and flaking in the first weeks; mild flushing in the first days at high concentration

Strengths: actives and evidence, cleansing base

What lowers the score: completeness for the purpose: for “oily scalp” — 48 %; tolerance: rinse-off product

Questions: hexyl nicotinate: nicotinic acid — a nicotinic-acid ester that dilates skin vessels: boosts blood flow and gives some people visible redness and warmth (Dermatologica 1987, laser Doppler in healthy volunteers); in toners it is claimed “for radiance” — a tolerance question, not an allergen; 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

  • Glycolic acid + Hyaluronic acid — reinforce each otherhyaluronate softens the dryness from the acid
  • Glycolic acid + Lactic acid — use together with caretwo AHAs in one product — combined acidity, irritation risk
  • Glycolic acid + Salicylic acid (BHA) — use together with careAHA + BHA together dry and irritate; alternate for sensitive skin
  • Hyaluronic acid + Panthenol (pro-vitamin B5) — reinforce each othertwo humectants with different action: moisture plus soothing
  • Lactic acid + Hyaluronic acid — reinforce each otherhyaluronate softens the dryness from the acid
  • Niacinamide (vitamin B3) + Glycolic acid — use together with careniacinamide needs a pH of 5 or above, glycolic acid about 3.5; in one product one of the two works worse — better to apply them at different times
  • Niacinamide (vitamin B3) + Salicylic acid (BHA) — reinforce each otherniacinamide cuts sebum and redness, the BHA clears pores — an acne classic
  • 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
  • PRUNUS AMYGDALUS DULCIS OIL base: coating, fillers · a light nourishing oil; rarely clogs pores in leave-on face products
  • 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

  • CALCIUM PANTOTHENATE base: coating, fillers · makes hair softer and easier to comb
  • MALTODEXTRIN base: coating, fillers · carbohydrate filler
  • SODIUM ASCORBYL PHOSPHATE label wording · an allergen (sodium (salt)) — matters when limiting salt, for example with blood pressure; the label says it is absent
  • NICOTINIC ACID questions · a nicotinic-acid ester that dilates skin vessels: boosts blood flow and gives some people visible redness and warmth (Dermatologica 1987, laser Doppler in healthy volunteers); in toners it is claimed “for radiance” — a tolerance question, not an allergen
  • TOCOPHERYL ACETATE base: coating, fillers · vitamin E at hundredths of a percent: keeps the oils of the formula (a cream or a capsule fill) from going rancid; at that share it protects the product, it is not vitamin E as an active
  • SODIUM HYALURONATE works · the active ingredient — what the product is for; form: sodium hyaluronate
  • PYRIDOXINE HCL base: coating, fillers · vitamin B6 in a trace dose; applied topically it does not reach the hair or follicle — a label line that does not change how the product works

  • CALCIUM GLUCONATE base: coating, fillers · draws water in and holds it in the upper layer of the skin
  • CAPRYLYL GLYCOL base: coating, fillers · a humectant that also holds bacteria back, which is why it often replaces part of the preservative.
  • 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
  • SODIUM STARCH OCTENYLSUCCINATE base: coating, fillers · hold the texture: gels, creams and foam do not separate
  • SILICA base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • TOCOPHEROL (MIXED base: coating, fillers · vitamin E at hundredths of a percent: keeps the oils of the formula (a cream or a capsule fill) from going rancid; at that share it protects the product, it is not vitamin E as an active
  • BETA-SITOSTEROL base: coating, fillers · helps the water-and-oil mix stay together in storage
  • SQUALENE base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • GLYCINE SOJA (SOYBEAN) OIL base: coating, fillers · the plant base: emollient oils, waxes and care extracts

  • PROPANEDIOL base: coating, fillers · a humectant and solvent from corn sugar: it holds water and helps actives dissolve. A gentler replacement for propylene glycol.
  • 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 %.
  • DISODIUM EDTA base: coating, fillers · bind hard-water metals so the formula stays stable and the foam works
