Why it works

Rich Conditioner, ingredients (concept render)
  • Behentrimonium chloride

    Its positive charge is drawn to bleached hair in lab microscopy. In tress tests, wet bleached hair snagged on every comb set and conditioner cut that to under 10%.

    Study 1 ↗Study 2 ↗Study 3 ↗Study 4 ↗

  • Cetearyl alcohol (a waxy fatty alcohol, not a drying one)

    Builds the thick, creamy gel that carries the conditioner. Lab work found gel strength depends on the conditioner-to-fatty-alcohol ratio, peaking near 6 to 10.

  • Coconut oil

    A triglyceride oil that entered hair in lab tests. In industry lab work it cut protein loss when used before or after washing; mineral oil did not.

  • Hydrolyzed keratin (wool protein fragments)

    Mid-size and large keratin fragments raised stiffness and cut breakage in relaxed, very curly hair in a lab test.

    Study 1 ↗Study 2 ↗

  • Amodimethicone (a silicone that sticks to damaged hair)

    A silicone that coats damaged hair. Reviews credit silicones with cutting friction and adding shine; not tested on curls. Judged safe as used by the CIR panel.

  • Polyquaternium-70 (conditioning polymer)

    In a supplier test it gave the best humidity resistance of four conditioning polymers. Tested in shampoo, not conditioner.

What's not in it

  • Added fragrance and fragrance allergens

    Fragrance is a main cause of contact allergy. In one clinic series, 15.7% of dermatitis patients reacted to a fragrance. Linalool and limonene appear in about half of fragranced products.

  • Essential oils

    Natural does not mean gentle. In 62,354 patch-tested clinic patients, 1.4% reacted to an essential oil alone. Ylang-ylang, sandalwood, jasmine, peppermint and oxidised tea tree oil led.

  • MI / MCI preservatives

    MI drove a rise in contact allergy in Europe. EU banned it from leave-ons in 2017; rinse-off is capped at 15 ppm. About 3 in 100 tested patients react.

  • Formaldehyde-releasing preservatives

    These preservatives slowly release formaldehyde, a known skin allergen. A 2022 clinical review says they still cause dermatitis, sometimes without being listed on the label.

  • Zinc pyrithione

    Banned in EU cosmetics from March 2022 as toxic for reproduction (hazard class). EU experts judged it safe in rinse-off anti-dandruff shampoo up to 1%, but no exemption was granted.

  • Harsh sulfates in daily products

    SLS is the standard irritant control in skin patch tests. A gentler cleanser, sodium lauroyl glutamate, irritated far less in 15 people. Fine for an occasional deep clean, not daily.

  • Coal tar

    Coal tar can cause folliculitis, irritation and allergy, and contains carcinogens seen in animals and workers (patients show no clear tumour rise). A non-tar shampoo matched it in one trial.

  • Methyldibromo glutaronitrile

    A preservative the EU banned in all cosmetics because allergy kept rising. In Denmark, positive allergy tests fell from 4.6% to 2.6% after the ban.

Who
human hair and silica surfaces (A*STAR Singapore, Ashland co-author)

Tested: behentrimonium chloride and methosulfate, cetrimonium chloride, stearalkonium chloride

Result: Longer-chain behentrimonium chloride cut wet combing force and deposited best; none reversed oxidative damage.

guideline

Result: Behentrimonium chloride is capped at 5.0% in rinse-off and 3.0% in leave-on hair products; cetrimonium chloride at 2.5% rinse-off and 1.0% leave-on; the sum of the three must stay under the stated cap because mixtures can irritate.
