How much cleansing you need depends on how fast your scalp gets oily, how much product you layer and your water. The consultation works that out.

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 Gentle

Removes light dirt and oil without stripping.

Expected lather Low

A thin, quick-collapsing lather.

Slip and detangling Little

Nothing here is built to reduce combing force.

Water-binding (humectants) High

Humectants near the top: binding water is one of its main jobs.

Scalp active None

No over-the-counter scalp active.

Hard-water defence Chelators present

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

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Protein None

No protein or amino acids in the list.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

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 (23)

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 · WATER (AQUA)
    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 Lauryl Glucoside
    General function

    A mild sugar-derived cleanser with a soft, low lather.

    Leading ingredient

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

    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.

    PubChem
    • nonionic cleanser
    • cleanser
  • 3 Sodium Cocoyl Alaninate
    General function

    A mild amino-acid cleanser with a soft, low foam.

    Leading ingredient

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

    May suitBuild-up-sensitive routines

    Cleansing is what lifts deposited films off the strand. How completely depends on which detergent it is and how high on the list it sits.

    DependsVery dry or highly damaged hair

    Every detergent removes some sebum along with the product it is there to wash out. Which detergent it is matters more than that there is one.

    • cleanser
  • 4 Glycerin
    General function

    Glycerin, also called glycerol, attracts moisture and mixes completely with water.

    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

    High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.

    May suitVery dry or highly damaged hair

    Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.

    DependsClimate-sensitive or frizz-prone hair

    Water moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.

    Scientific Reports
    • humectant
  • 5 Coco-Betaine
    General function

    A coconut-derived mild cleanser that boosts foam and softens stronger detergents.

    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
  • 6 Coco-Glucoside
    General function

    A sugar-derived, low-foaming cleanser used in gentle and curly-method 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.

    • nonionic cleanser
    • cleanser
  • 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 here, the order stops meaning much. These are usually used at 1% or less.
  • 8 1,2-Hexanediol
    General function

    A preservative booster that also holds a little moisture and helps other ingredients dissolve.

    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 adds less weight than oils or butters do.

    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.

    PubChem
    • preservative
    • humectant
    • solvent
  • 9 Arginine Hcl
    General function

    A salt form of the amino acid arginine, used for moisture binding and to adjust pH.

    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 suitVery dry or highly damaged hair

    Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

    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.

    DependsProtein-sensitive hair

    The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

    • amino acid
    • humectant
  • 10 Benzoic Acid

  • 11 Cellulose
    General function

    Plant fibre used to thicken and give body to a 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 suitCurls or waves needing flexible hold

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

    • thickener
    • gum
  • 12 Cellulose Gum
    General function

    A cellulose thickener used for body and slip.

    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.

  • 13 CITRIC ACID CITRUS LIMON (LEMON) FRUIT EXTRACT (CITRUS LIMON FRUIT EXTRACT)
  • 14 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.

  • 17 HYDROXYPROPYL GUAR HYDROXYPROPYLTRIMONIUM
  • 18 CHLORIDE
  • 19 Lysine Hcl
    General function

    A salt form of the amino acid lysine, used in conditioning blends.

    PubChem
    • amino acid
  • 20 Red 33 (CI 17200)
    General function

    A certified colour that tints the product itself. It does not colour hair.

    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 suitGray, silver, or brass-prone hair

    A violet or blue colorant sits opposite yellow on the colour wheel, so a trace of it deposited on the surface makes a warm cast read cooler. It washes out over the following few washes.

    • colourant
  • 21 SODIUM
  • 22 BENZOATE
  • 23 Trisodium Ethylenediamine Disuccinate
    General function

    A readily biodegradable chelator used in place of EDTA to bind hard-water minerals.

    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.

How we work this out
  1. 6.76 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 $17.19 is the price we have observed for the 6.76 oz. We need three stores before we call a price commonly seen.
  3. Good value under $12 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.70/oz; at 6.76 oz that is $12. Under that line you are paying less than most of them.
  4. About $16 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 6.76 oz.

More from Rene Furterer

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.
  • 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.
  • 2 sources consulted for this product (0 manufacturer or regulatory, 0 retailer, 2 editorial), last checked 2026-10-08.
  • Ingredient references are linked for 8 of 14 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 2026-10-08.
