How the score is calculated
  • Actives and evidence0.4Little evidence of effect
  • Completeness for the purpose1.0For “dry and damaged hair” — 100 %; a narrow formula for one purpose
  • Tolerance0.5Debatable ingredient groups: BHT and BHA (antioxidants), fragrance and its allergens (skin test positive in 13 of 100 tested); comedogenic ingredients at a notable share (may clog pores): avocado oil, isopropyl myristate
  • adults
  • children
  • pregnancytopical, in a rinse-off product — allowed
  • colour-treated hair
  • tree nut allergya nut oil — best avoided with a severe tree nut allergy
  • nut allergywith a almond allergy — ask a doctor
  • acne-pronemay clog pores in leave-on face products
  • 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.
  • 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.
  • 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:
  • leave-on
a few drops along damp or dry lengths
When to expect an effect: smoothness and shine — right away, until the next wash

Ingredients — 24 components · 1 works

What works: 1 of 24 ingredients: macadamia oil. 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: little evidence of effect; tolerance: debatable ingredient groups: bht and bha, fragrance and its allergens

A frequent buyer question, with no proven harm at these levels.

Tashe Professional Liquid Silk leave-in hair oil is a product whose active ingredient is macadamia oil. The concentration is not declared, but the active sits above the 1 % line in the list — a working share is likely. There is little evidence of effect: macadamia nut oil rich in palmitoleic acid, close to natural sebum: softens, adds shine and eases combing. It does not rebuild the hair structure — the effect lasts until the next wash. The formula has 24 ingredients, 1 of which does the work; the rest is the formula base. Worth noting: Parfum, Hexyl Cinnamal, Linalool, Limonene, Geraniol, Coumarin, Citronellol, Dimethyl Phenethyl Acetate, Linalyl Acetate, Citrus Limon Peel Oil (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); BHT (antioxidants that keep oils from going rancid: hundredths of a percent in cosmetics, and E321 and E320 in supplements. A frequent buyer question, with no proven harm at these levels.). 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. By the list, no alcohol (alcohol denat), sulfates (SLS/SLES), formaldehyde releasers, isothiazolinones (MIT/MCI), parabens, mineral oils and petrolatum, soap, gelatin in the coating, toning dyes, tar. Suitable for: adults, children, pregnancy, colour-treated hair. tree nut allergy, nut allergy, acne-prone, sensitive skin, atopic skin — ask a doctor. fragrance allergy — not without a doctor. Use: a few drops along damp or dry lengths. When to expect an effect: smoothness and shine — right away, until the next wash. Label score — 5.8 out of 10 (little evidence of effect; debatable ingredient groups: bht and bha (antioxidants), fragrance and its allergens (skin test positive in 13 of 100 tested); comedogenic ingredients at a notable share (may clog pores): avocado oil, isopropyl myristate).
