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.
A reset wash that removes oil, buildup, and most residue.
Thick foam that spreads quickly through the hair.
Conditioning agents are present, lower in the list.
Humectants appear, but low enough to be a minor part.
No over-the-counter scalp active.
Contains chelators, which bind hard-water and pool minerals.
Nothing here needs a detergent wash to remove.
No protein or amino acids in the list.
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

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

Sodium Laureth Sulfate
General function
A strong, high-foaming cleanser and the most common shampoo detergent. It removes oil and product efficiently, which can be more than dry or colour-treated hair wants.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.

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.

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 Gluconate

A gentle, biodegradable chelator that binds hard-water minerals in place of EDTA.

Caprylic/Capric Triglyceride
General function
A light, refined coconut-derived oil that spreads easily and does not go rancid. It gives slip without a heavy feel.

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.

Polyquaternium-10
General function
A cellulose-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.
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.
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.

PEG-6 Caprylic/Capric Glycerides

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.

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.

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
- 3 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.
- Seen at $5.79 is the price we have observed for the 3 oz. We need three stores before we call a price commonly seen.
- Good value under $1 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.23/oz; at 3 oz that is $1. Under that line you are paying less than most of them.
- Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
- About $1 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 3 oz.
Formula
The formula carries the systems a shampoo is built around, and it sits in the middle of the range for shampoos per ounce.
How the score is counted
- 8 products we score as doing the same job cost less per ounce
- Costs more per ounce than 62% of the 1544 shampoos we’ve priced
- Covers 6 of the 7 things a shampoo should do
- Reviewers mention 4 things they like about how it performs

- Slip for detanglingReduces the force it takes to comb wet hair.2 pts
- A humectantBinds water into the hair.1 pt

- A pH adjusterBrings the formula to the acidic pH hair prefers.1 pt
- No detergent-dependent filmNothing that needs a clarifying wash to remove.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
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.
- 5 sources consulted for this product (4 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-09-25.
- Ingredient references are linked for 7 of 13 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 2026-09-02.
