How the score is calculated
  • Actives and evidence0.6No proven effect when applied: amaranth seed extract
  • Completeness for the purpose0.2For “protection from heat styling” — 21 %; film-forming styling polymers; hydrolysed wheat protein; could be added without conflict: film-forming styling polymers, hydrolysed wheat protein; below threshold: panthenol (pro-vitamin b5); a narrow formula for one purpose
  • Tolerance0.8Debatable ingredient groups: denatured alcohol, fragrance and its allergens (skin test positive in 13 of 100 tested)

Free from:
  • 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: A dryer and a flat iron heat hair above 200 °C and break down its protein. Hair cannot be fully protected, but a polymer film and an oil on the surface noticeably reduce breakage — this was measured on tresses in the laboratory.
When:
  • leave-on
  • morning
  • daytime
  • evening
any time, can be applied often
When to expect an effect: soothing — days; barrier — 2–4 weeks; tone, pores — 4–8 weeks; sebum — 2–4; do not expect a separate effect from amaranth; softness — immediately; barrier — 2–4 weeks
What is normal: mild flushing in the first days at high concentration; the smoothness comes from the formula’s oils and polymers, not from it; a light film on the skin

Ingredients — 24 components · 4 work

What works: 4 of 24 ingredients: panthenol, niacinamide, amaranth seed extract and 1 more. A dryer and a flat iron heat hair above 200 °C and break down its protein. Hair cannot be fully protected, but a polymer film and an oil on the surface noticeably reduce breakage — this was measured on tresses in the laboratory.

What lowers the score: actives and evidence: no proven effect when applied: amaranth seed extract; completeness for the purpose: for “protection from heat styling” — 21 %; tolerance: debatable ingredient groups: denatured alcohol, fragrance and its allergens

Questions: denatured alcohol — evaporates fast and degreases; frequent contact can dry the skin — a tolerance question, not a regulatory one; does not clog pores; fragrance and its allergens: citral, fragrance, limonene, linalool, terpineol — 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

  • PEG-40 HYDROGENATED CASTOR OIL base: coating, fillers · coating glazing agent
  • POLYGLYCERYL-3 PCA 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
  • AMARANTHUS CAUDATUS SEED EXTRACT works · the active ingredient — what the product is for; form: amaranth seed extract
  • CITRAL 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

  • CITRUS AURANTIUM DULCIS (ORANGE) PEEL OIL (CITRUS AURANTIUM PEEL OIL base: coating, fillers · the plant base: emollient oils, waxes and care extracts
  • DIISOSTEARYL MALATE base: coating, fillers · fills the gaps between skin flakes, so the surface feels smooth
  • FRAGRANCE (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
  • GERANYL ACETATE base: coating, fillers · gives skin or hair a feeling of vigour
  • HELIANTHUS ANNUUS (SUNFLOWER) SEED OIL (HELIANTHUS ANNUUS SEED OIL base: coating, fillers · a light emollient oil rich in linoleic acid (in tablets — a coating component); does not clog pores
  • HEXAMETHYLINDANOPYRAN base: coating, fillers · gives the product its scent
  • CYMBOPOGON SCHOENANTHUS OIL (LEMONGRASS OIL base: coating, fillers · the plant base: emollient oils, waxes and care extracts

  • SIMMONDSIA CHINENSIS (JOJOBA) SEED OIL (SIMMONDSIA CHINENSIS SEED OIL works · the active ingredient — what the product is for; form: seed oil
  • SODIUM CITRATE base: coating, fillers · tune the acidity and texture; salt is a common shampoo thickener
  • TERPINEOL 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
  • TETRAMETHYL ACETYLOCTAHYDRONAPHTHALENES base: coating, fillers · softens the skin and helps it hold water — the most common role in creams
  • TOCOPHEROL 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

René Furterer Style Heat Protection Spray is a product whose active ingredient is panthenol (pro-vitamin b5) + niacinamide (vitamin b3) + amaranth seed extract + jojoba oil. The concentration is not declared and the active sits after the 1 % line — more for the label than for the effect. The effect is moderately supported: panthenol (pro-vitamin b5). The effect is supported by studies: niacinamide (vitamin b3). There is no evidence of effect: amaranth seed extract. There is little evidence of effect: jojoba oil. The formula has 24 ingredients, 4 of which do the work; the rest is the formula base.
