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.

Cleansing strength Strong

Removes oil, buildup, and most residue — a reset wash.

Expected lather High

Thick foam that spreads quickly through the hair.

Slip and detangling Moderate

Conditioning agents are present, lower in the list.

Water-binding (humectants) Low

Humectants appear, but low enough to be a minor part.

Scalp active None

No over-the-counter scalp active.

Hard-water defence None

No chelating agent in the list.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Protein Minor

Protein appears, low enough to be a supporting ingredient.

Fragrance Prominent

Fragrance sits in the first eight ingredients — 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. These 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 (23)

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

  • 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 Ammonium Lauryl Sulfate
    General function

    A sulfate detergent similar in strength to sodium lauryl sulfate, used for fast, high foam.

    Leading ingredient

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

    May suitBuild-up-sensitive routines

    A sulfate detergent removes deposited silicone, wax and styling films in one wash, which is what resets a routine before build-up is visible.

    May suitFine or easily flattened hair

    Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.

    May not suitDry, coarse, or high-porosity hair

    Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.

    PubChem
    • sulfate cleanser
    • cleanser
  • 3 Sodium Myreth Sulfate
    General function

    A strong anionic detergent. It foams readily and cleans thoroughly, which is more than dry or colour-treated hair usually wants.

    Leading ingredient

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

    May suitBuild-up-sensitive routines

    A sulfate detergent removes deposited silicone, wax and styling films in one wash, which is what resets a routine before build-up is visible.

    May suitFine or easily flattened hair

    Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.

    May not suitDry, coarse, or high-porosity hair

    Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.

    PubChem
    • sulfate cleanser
    • cleanser
  • 4 Sodium Cocoamphoacetate
    General function

    A very mild cleanser common in baby and sensitive-scalp shampoos.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    May suitDry, coarse, or high-porosity hair

    Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

    May suitVery dry or highly damaged hair

    One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.

    May not suitBuild-up-sensitive routines

    The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.

    • amphoteric cleanser
    • secondary cleanser
    • cleanser
  • 5 MIPA-Lauryl Sulfate
    General function

    A lauryl sulfate salt. It is a sulfate detergent: high-foaming and thorough.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    • sulfate cleanser
    • cleanser
  • 6 Sodium Chloride
    General function

    Table salt. In shampoo it is used to thicken the liquid, not to treat the hair.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    PubChem
    • salt
    • thickener
  • 7 Glycol Distearate
    General function

    A wax that gives shampoo its pearly look and a slightly richer feel.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

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

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

    PubChem
    • opacifier
    • emollient
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 8 Fragrance · Parfum (Fragrance)
    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
  • 9 Citric Acid
    General function

    Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

    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

    Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

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

    The acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.

    May suitGray, silver, or brass-prone hair

    Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

    International Journal of Trichology
    • pH adjuster
    • hard-water chelator
  • 10 Guar Hydroxypropyltrimonium Chloride
    General function

    A conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.

    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 suitCurls or waves needing flexible hold

    Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

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

    Cationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.

    May suitMaximum-hold styling

    A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.

    • conditioning agent
    • polymer
    • gum
  • 11 Cocamide MEA
    General function

    A coconut-derived thickener that stabilises foam and gives shampoo its body.

    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 suitDry, coarse, or high-porosity hair

    Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

    May suitVery dry or highly damaged hair

    A sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.

    May not suitBuild-up-sensitive routines

    Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.

    • secondary cleanser
    • nonionic cleanser
    • thickener
  • 12 Laureth-10
    • emulsifier
  • 13 Triethylene Glycol
    General function

    A small glycol used as a carrier and to hold a little water.

    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 suitFine or easily flattened hair

    Light and water-binding rather than oily, so it hydrates without contributing weight.

    May suitVery dry or highly damaged hair

    A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

    DependsClimate-sensitive or frizz-prone hair

    A humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

    • humectant
    • solvent
  • 14 Benzyl Alcohol
    • preservative
    • solvent
  • 15 Propylene Glycol
    General function

    A small humectant and solvent that keeps formulas stable and helps active ingredients spread.

    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 suitFine or easily flattened hair

    Light and water-binding rather than oily, so it hydrates without contributing weight.

    May suitVery dry or highly damaged hair

    A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

    PubChem
    • humectant
    • solvent
  • 16 Citrus Limon (Lemon) Peel Oil
    General function

    A cold-pressed citrus oil used for a fresh scent; naturally high in limonene.

    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

    Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.

    • botanical extract
    • essential oil
    • fragrance
  • 17 Butyrospermum Parkii (Shea) Butter
    General function

    A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.

    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 suitDry, coarse, or high-porosity hair

    Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.

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

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

    May suitVery dry or highly damaged hair

    A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.

    • butter
    • emollient
    • sealant
  • 18 Hydrolyzed Keratin
    General function

    Fragments of the same protein hair is made of. They fill gaps on damaged strands and make hair feel firmer for a few washes.

    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 suitFrizz-prone, damaged, or high-friction hair

    Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

    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.

    DependsCurls or waves needing flexible hold

    How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.

    International Journal of Cosmetic Science
    • film former
    • protein
    • hydrolysed protein
  • 19 Macadamia Ternifolia Seed Oil · Macadamia Integrifolia Seed Oil
    General function

    A cushiony oil that absorbs reasonably well, common in smoothing treatments.

    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 suitDry, coarse, or high-porosity hair

    Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

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

    A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

How we work this out
  1. 33.8 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. Seen at $49.99 is the price we have observed for the 33.8 oz. We need three stores before we call a price commonly seen.
  3. Good value under $28 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.83/oz; at 33.8 oz that is $28. Under that line you are paying less than most of them.
  4. About $43 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 33.8 oz.

Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Final decision

Should you buy it?

Good for the right person
Best user

Scalps that oil up within a day — for a proper reset wash and something that will not weigh hair down

Biggest tradeoff

Worth skipping for anyone sensitive to fragrance, sulfate-free routines and fresh keratin treatments, or dry or damaged hair

We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.

Claims check

What the brand says, against what the formula shows

Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

How this page was made

  • Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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.
  • The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
  • 6 sources consulted for this product (5 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
  • Ingredient references are linked for 6 of 14 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
  • We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
  • 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.
