Whether this much richness suits you depends on your strand thickness, porosity and how easily your hair goes flat. We work that out in the consultation.

What the formula actually does

Read from the label, not the marketing

Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.

Slip and detangling High

Conditioning agents sit high in the list, so this is a detangling formula.

Oils and butters None

No oils or butters in the list.

Water-binding (humectants) None found

No humectants, so nothing here pulls water into the hair.

Protein None

No protein or amino acids in the list.

Needs detergent to remove Yes

Water-insoluble silicones or waxes: a detergent wash is what removes them.

Hard-water defence Chelators present

Contains chelators, which bind hard-water and pool minerals.

Fragrance Prominent

Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

Ingredients that matter

The ingredients that change a decision

The workhorse ingredients, plus anything lower down that changes a decision. The chips name what an ingredient does. They are not safety scores, and no ingredient here is rated good or bad on its own.

Full ingredient list (12)

In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.

  • 1 Water · Aqua (Water)
    General function

    The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    • solvent
  • 2 Hydrogen Peroxide
    General function

    An oxidising agent. In hair products it lightens pigment and opens the cuticle; its presence marks this as a chemical treatment, not a conditioning product.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    • active
  • 3 Polysorbate 20
    General function

    Keeps fragrance and oils dissolved in a watery formula so it stays clear.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    • solubilizer
    • emulsifier
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 4 Fragrance · Fragrance/Parfum
    General function

    An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May not suitFragrance-sensitive routines

    Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

    • fragrance
    • declared fragrance
  • 5 Citrus Medica Limonum (Lemon) Fruit Extract
    General function

    An extract from the fruit of Citrus Medica. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    • botanical extract
  • 6 Ananas Sativus (Pineapple) Fruit Extract
    General function

    An extract from the fruit of Pineapple (Ananas Sativus). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    • botanical extract
  • 7 Silicone Quaternium-8
    General function

    A conditioning silicone that clings to damaged areas for smoothing and heat protection.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitClimate-sensitive or frizz-prone hair

    A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

    May suitFrizz-prone, damaged, or high-friction hair

    Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.

    May suitMaximum-hold styling

    Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

    • silicone
    • film former
    • conditioning agent
  • 8 Disodium Phosphate
    General function

    A buffering salt that keeps pH stable as the product ages.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    DependsFrizz-prone, damaged, or high-friction hair

    pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

    PubChem
    • pH adjuster
    • salt
  • 9 Phosphoric Acid
  • 10 Disodium EDTA
    General function

    Grabs metal ions from hard water so they cannot dull the hair or destabilise the formula.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitBuild-up-sensitive routines

    Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.

    May suitGray, silver, or brass-prone hair

    Copper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.

    PubChem
    • hard-water chelator
  • 11 Coumarin
    General function

    A sweet, hay-like fragrance component listed separately as a recognised allergen.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May not suitFragrance-sensitive routines

    One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.

3 oz

Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.

How we work this out
  1. 4 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
  2. Commonly seen is the middle half of current prices for the 4 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
  3. Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.

How this page was made

  • Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one product.
  • The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
  • Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
  • 1 source consulted for this product (0 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-11-01.
  • Ingredient references are linked for 3 of 5 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
  • We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
  • Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
  • This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
  • Formula readings: derivation v23. Record last updated 2026-11-01.
