How the score is calculated
  • Actives and evidence0.1No proven effect when applied: mustard seed
  • Completeness for the purpose0.0For “hair shedding (topical)” — 4 %; niacinamide (vitamin b3); could be added without conflict: niacinamide (vitamin b3); below threshold: mustard seed; a narrow formula for one purpose
  • Cleansing base0.6Harsh surfactants: sodium laureth sulfate (SLES); mild surfactants: cocamidopropyl betaine, coco-betaine, lauryl glucoside; irritation potential of the base — 36 % of SLS
  • Tolerance0.2Rinse-off product; debatable groups: benzyl alcohol, 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
  • dry scalpmustard is drying: on a dry scalp it increases tightness and flaking
  • pregnancyno studies in pregnancy — discuss with a doctor
  • acne-pronemay clog pores in leave-on face products
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
on the scalp only, not along the length; keep no longer than the time stated on the pack
When to expect an effect: burning — within the first minutes; do not count on hair growth
What is normal: moderate burning is the expected action of mustard, not a sign of a result

Ingredients — 30 components · 1 works

What works: 1 of 30 ingredients: mustard seed. 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.

What lowers the score: actives and evidence: no proven effect when applied: mustard seed; completeness for the purpose: for “hair shedding” — 4 %; 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; 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; benzyl alcohol; isothiazolinone preservatives (MIT/MCI): methylchloroisothiazolinone, methylisothiazolinone

  • вода 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
  • лауретсульфат натрия questions · the main cleansing surfactant; can dry a sensitive scalp — the reason people look for «sulfate-free»; unrestricted in rinse-off products
  • кокобетаин base: coating, fillers · an amphoteric surfactant from coconut oil: it cleanses and stabilises foam. Slightly harsher than cocamidopropyl betaine, yet clearly milder than the sulfates.
  • лаурилглюкозид base: coating, fillers · a sugar surfactant: it cleanses gently and foams lightly, usually paired with betaines.
  • кокамидопропилбетаин 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.
  • ПЭГ-3 дистеарат base: coating, fillers · coating glazing agent
  • кокамид MIPA base: coating, fillers · a thickener and foam booster from coconut oil: it barely cleanses on its own, it makes the foam denser.
  • лаурет-4 base: coating, fillers · an ethoxylated emulsifier; may clog pores in leave-on face products; a finished product with it is not always comedogenic

Belita SPA Mustard Shampoo is a product whose active ingredient is mustard seed. The concentration is not declared and the active sits after the 1 % line — more for the label than for the effect. There is no evidence of effect: mustard in hair masks does the same as pepper: it irritates the scalp and brings a rush of blood, hence the burning. There are no studies in which this turns into hair growth in people. The burning here is not a sign that it works, it is the limit of what the skin tolerates. The formula has 30 ingredients, 1 of which does the work; the rest is the formula base. Worth noting: Sodium Laureth Sulfate (the main cleansing surfactant; can dry a sensitive scalp — the reason people look for «sulfate-free»; unrestricted in rinse-off products); Parfum (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); Benzyl Alcohol; Methylchloroisothiazolinone, Methylisothiazolinone. 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. By the list, no alcohol (alcohol denat), formaldehyde releasers, parabens, mineral oils and petrolatum, soap, silicones, gelatin in the coating, toning dyes, tar. Suitable for: adults. dry scalp, pregnancy, acne-prone — ask a doctor. sensitive scalp, atopic skin, fragrance allergy, prone to contact allergy — not without a doctor. Use: on the scalp only, not along the length; keep no longer than the time stated on the pack. When to expect an effect: burning — within the first minutes; do not count on hair growth. Label score — 2.0 out of 10 (no proven effect when applied: mustard seed; for “hair shedding (topical)” — 4 %; niacinamide (vitamin b3); could be added without conflict: niacinamide (vitamin b3); below threshold: mustard seed; a narrow formula for one purpose; harsh surfactants: sodium laureth sulfate (sles); mild surfactants: cocamidopropyl betaine, coco-betaine, lauryl glucoside; irritation potential of the base — 36 % of sls; rinse-off product; debatable groups: benzyl alcohol, 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)).
