What the formula actually does
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 in the working part of the formula.
Carries an over-the-counter scalp active, listed under Drug Facts.
No chelating agent in the list.
Nothing here needs a detergent wash to remove.
No protein or amino acids in the list.
Fragrance is listed; it sits below the working ingredients.
Ingredients that matter
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.

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.
An over-the-counter anti-dandruff active that reduces the yeast associated with flaking. Its percentage is stated in the drug facts panel.
Listed in the first three ingredients, it is likely a structural part of this formula.
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Listed in the first three ingredients, it is likely a structural part of this formula.
A sulfate detergent similar in strength to sodium lauryl sulfate, used for fast, high foam.
Listed in the first three ingredients, it is likely a structural part of this formula.
A sulfate detergent can lift deposited silicone, wax and styling films, which is what resets a routine before build-up is visible.
Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.
Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
Among 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.
A hold polymer that forms a firm, humidity-resistant film. It is the usual source of a hard cast in gels.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
A gentle preservative helper that also holds a little moisture.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Humectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.
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.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Holds hard-water minerals in solution so they rinse away instead of depositing on the 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.
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.
A sugar-derived, low-foam cleanser used in gentle and curly-method shampoos.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
A sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.
Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.
A guar-bean conditioning polymer that deposits during rinsing. It is why a strong shampoo can still leave hair combable.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.
Cationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.
A mild sugar-derived cleanser with a soft, low lather.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
A sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.
Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.
Produces the cooling, tingling feeling on the scalp. The sensation is real; it is not evidence that anything else is happening.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
It hydrates without adding oil or a film, which is the combination fine hair usually needs.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.
A strong base used in trace amounts to raise pH; fully neutralised in the finished product.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
The 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. Alkaline conditions raise the fibre's surface charge and lift the scales — but the finished pH is not on the label.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
A citrus-smelling fragrance component that EU rules require to be named separately because some people react to it.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
This product is an over-the-counter drug as well as a cosmetic. It treats a cosmetic scalp condition; it does not diagnose or treat disease.

Priced above the products that do the same job. Stores sell it above the $14 line; products that do this job typically go for about $25 at this size.
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.
Formula
The formula carries the systems a shampoo is built around, and it sits in the middle of the range for shampoos per ounce.
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
Formulas that do the same things (cleanse, condition, coat or hold) for less per ounce. Scent, texture and where you buy them can still differ.

Claims check
Claims are quoted from the brand. We mark a claim supported, partly supported or conflicting only when the ingredient list speaks to it. Everything else stays "stated by the brand". That isn’t a criticism: most claims can’t be checked from a label.
