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.
Removes oil, buildup, and most residue — a reset wash.
Thick foam that spreads quickly through the hair.
Conditioning agents sit high in the list — this is a detangling formula.
Humectants in the working part of the formula.
No over-the-counter scalp active.
Chelators are present — they bind hard-water and pool minerals.
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. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

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.
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 high-foaming, strongly cleansing detergent. It clears build-up thoroughly and is the harsher of the two common sulfates.
Listed in the first three ingredients, it is likely a structural part of this formula.
A sulfate detergent removes deposited silicone, wax and styling films in one wash, 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 co-cleanser that keeps foam stable in hard water.
Listed in the first three ingredients, it is likely a structural part of this formula.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
A coconut-derived thickener that stabilises shampoo foam and gives the liquid its body.
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.
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.
Wheat germ oil, a heavier oil used in small amounts for conditioning.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.
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.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A positively charged conditioning polymer. It leaves a thin film that cuts static and eases combing, and it survives rinsing better than a simple conditioner.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Cationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
A cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
A cellulose thickener used for slip and light hold in gels and creams.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.
A soft film binds neighbouring strands together, which is most of what keeps flyaways lying down without stiffness.
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.
Binds the metal ions in hard water so they cannot dull hair or destabilise the formula.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.
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.
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.
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 fragrance component with a faint balsamic scent, named separately on the label because it is a recognised contact allergen.
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.

Formula
A complete read of the format at an ordinary price: mid-range per ounce among shampoos, with the working systems present.
The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job, for less
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
Hair that stiffens on protein — for a protein-free formula and a proper reset wash
Less suited to anyone sensitive to fragrance, sulfate-free routines and fresh keratin treatments, or dry or damaged hair

Claims check
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.
