How the score is calculated
  • Actives and evidence0.8Effect moderately supported
  • Completeness for the purpose1.0For “dry and damaged hair” — 100 %; without coconut oil — the only oil proven to reduce protein loss; could be added without conflict: coconut oil; a broad formula across 6 purposes
  • Cleansing base0.7Harsh surfactants: sodium laureth sulfate (SLES); mild surfactants: cocamidopropyl betaine, coco-glucoside, decyl glucoside; irritation potential of the base — 34 % 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
  • pregnancyallowed per the leaflet
  • children
  • babies
  • sensitive skinrare contact allergy to impurities
  • atopic skinfragrance is a common trigger
  • nut allergywith a almond allergy — ask a doctor
  • acne-pronemay clog pores in leave-on face products
  • 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
  • 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: Damaged hair is helped on two fronts: oils that penetrate the shaft (only coconut oil is proven) and a film on the outside — silicones, panthenol, hydrolysed proteins. One from each front is enough; “collagen” and “biotin” in a shampoo work only on the label.
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

What works: 1 of 24 ingredients: panthenol. Damaged hair is helped on two fronts: oils that penetrate the shaft (only coconut oil is proven) and a film on the outside — silicones, panthenol, hydrolysed proteins. One from each front is enough; “collagen” and “biotin” in a shampoo work only on the label.

Strengths: completeness for the purpose

What lowers the score: actives and evidence: effect moderately supported; 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; 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; fragrance and its allergens: fragrance, linalool, limonene

  • 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.
  • Sodium Chloride base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • Betaine base: coating, fillers · draws water in and holds it in the upper layer of the skin
  • Potassium Laureth-4 Carboxylate base: coating, fillers · an ethoxylated emulsifier; may clog pores in leave-on face products; a finished product with it is not always comedogenic
  • Coco-Glucoside base: coating, fillers · a sugar surfactant made from coconut oil and glucose: it cleanses gently with modest foam. A common base for baby and sulfate-free shampoos.
  • Decyl Glucoside base: coating, fillers · one of the gentlest cleansing ingredients: a sugar surfactant that barely disturbs the skin barrier.
  • Panthenol works · the active ingredient — what the product is for; form: panthenol
  • Persea Gratissima (Avocado) Oil base: coating, fillers · a rich nourishing oil; may clog pores in leave-on face products
  • Hamamelis Virginiana (Witch Hazel) Leaf Extract base: coating, fillers · plant and algae extracts and floral waters: flavouring and marketing components — at these shares there is no proven effect on the skin; rare reactions in people allergic to that particular plant
  • Olive Oil Glycereth-8 Esters base: coating, fillers · a nourishing emollient oil; rarely clogs pores in leave-on face products
  • Almond Oil Glycereth-8 Esters base: coating, fillers · a light nourishing oil; rarely clogs pores in leave-on face products
  • Polyquaternium-7 base: coating, fillers · a conditioning polymer: it removes static, makes combing easier and softens the foam.
  • Glycerin base: coating, fillers · a humectant: coats the tablet, holds moisture in creams and shampoos; does not clog pores
  • Tetrasodium Glutamate Diacetate base: coating, fillers · binds traces of metal from water that would spoil the product
  • Potassium Sorbate base: coating, fillers · a mild preservative against mould and yeast: used both in cosmetics and in foods and supplements (E202).
  • 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 %.
  • 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
  • Citric Acid base: coating, fillers · acidity regulator
  • Sodium Hydroxide base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • 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
  • Linalool 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
  • Limonene 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
