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.
Removes oil and product; leaves some conditioning behind.
An ordinary shampoo lather.
Conditioning agents are present, lower in the list.
Humectants near the top: binding water is one of its main jobs.
No over-the-counter scalp active.
Contains chelators, which bind hard-water and pool minerals.
Nothing here needs a detergent wash to remove.
Protein appears, low enough to be a supporting ingredient.
Fragrance is listed; it sits below the working ingredients.

Full ingredient list (27)
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
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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent

2
Cocamidopropyl Betaine
General function
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Indian Journal of DermatologyMay suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May not suitBuild-up-sensitive routinesThe mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
DependsVery dry or highly damaged hairAmong the mildest detergents in use — it is what baby shampoos are built on — but it is almost always the second detergent in a formula. How much a wash strips is still decided by the primary detergent listed above it.

Sodium Cocoyl Isethionate
General function
A mild cleanser that gives a creamy lather and leaves hair less stripped than sulfates.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitCurls or waves needing flexible holdThe detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.
May suitDry, coarse, or high-porosity hairA gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.
May suitVery dry or highly damaged hairCleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Scientific ReportsMay suitDry, coarse, or high-porosity hairHigh-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 hairBinds 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 hairWater 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.

Sodium Hyaluronate
· Sodium Hyaluronate (Hyaluronic Acid)
General function
A large water-binding molecule that sits on the surface holding moisture.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

Oryza Sativa Extract
· Oryza Sativa (Violet Rice) Extract
General function
An extract of Oryza Sativa. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

SH-Polypeptide-121
General function
A bioengineered polypeptide used at low levels in scalp-positioned formulas.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May not suitProtein-sensitive hairA large surface-depositing protein. If protein reliably makes your hair feel rigid, this is the form most likely to do it.
DependsVery dry or highly damaged hairUnhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.

Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitBuild-up-sensitive routinesCleansing 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 hairEvery 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.

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.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitCurls or waves needing flexible holdGums thicken and set soft, which gives definition that bends rather than a rigid cast.
May suitFrizz-prone, damaged, or high-friction hairCationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.
May suitMaximum-hold stylingA styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.

Polyquaternium-7
General function
A conditioning polymer that improves wet combing and adds body. Repeated use can build up on fine hair.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitCurls or waves needing flexible holdCationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
May suitFrizz-prone, damaged, or high-friction hairA cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

Tetrasodium Glutamate Diacetate
General function
A biodegradable hard-water chelator used in place of EDTA.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
PubChemMay suitBuild-up-sensitive routinesBinds 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 hairCopper 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.

1,2-Hexanediol
General function
A preservative booster that also holds a little moisture and helps other ingredients dissolve.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it adds less weight than oils or butters do.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

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.

International Journal of TrichologyMay suitBuild-up-sensitive routinesHolds hard-water minerals in solution so they rinse away instead of depositing on the hair.
May suitFrizz-prone, damaged, or high-friction hairThe 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 hairWhere 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 TrichologyDependsFrizz-prone, damaged, or high-friction hairThe alkali half of a pH-adjusting pair, used in small amounts to bring a formula up to its target rather than to make it alkaline.

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
- 10 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.
- Commonly seen is the middle half of current prices for the 10 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- Good value under $10 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.98/oz; at 10 oz that is $10. Under that line you are paying less than most of them.
- About $12 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 10 oz.
Formula
A complete formula at an ordinary price: mid-range per ounce among shampoos, with the working systems in place.
How the score is counted
- 3 products that do the same job cost less per ounce
- Costs less per ounce than 53% of the 1544 shampoos we’ve priced
- Covers 7 of the 7 things a shampoo should do
- Reviewers mention 2 recurring complaints

The formula score measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.
Does the same job, for less

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.
- 3 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-10-31.
- Ingredient references are linked for 8 of 15 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.
