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 and product; leaves some conditioning behind.
An ordinary shampoo lather.
Conditioning agents are present, lower in the list.
Humectants in the working part of the formula.
No over-the-counter scalp active.
Chelators are present — they bind hard-water and pool minerals.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Protein appears, low enough to be a supporting ingredient.
Fragrance is listed; it sits below the working ingredients.

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 mild cleanser that foams well in hard water, usually paired with disodium 2-sulfolaurate.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
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.
A mild cleanser that gives a creamy lather and leaves hair less stripped than sulfates.
Listed in the first three ingredients, it is likely a structural part of this formula.
The detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.
A gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.
Cleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.
A mild co-cleanser that keeps foam stable in hard water.
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.
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 mild cleanser used with sodium methyl 2-sulfolaurate in gentle shampoo systems.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
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.
A coconut-derived, ethoxylated amide used to thicken a cleanser and keep its foam stable.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A secondary detergent adjusts foam and mildness rather than deciding how much a wash removes; read the primary detergent above it.
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 thickener that gives shampoo and body wash their pourable, slightly gel-like texture.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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 light oil used for shine and slip, often alongside rice-derived proteins.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
Silk protein broken into amino acids, used for slip and shine rather than strength.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
An amino acid of the kind hair protein is built from. Small enough to sit inside the cuticle, and used for water binding rather than strength.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
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.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
Keratin broken all the way down to individual amino acids. Small enough to sit inside the cuticle, used for softness rather than firmness.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.
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.
Hydration with no oil attached, so it adds very little weight even high on a list.
Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.
An amino-acid derivative used in strengthening-positioned products; it is small enough to enter the strand.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
Biotin bonded to a short peptide, included in thinning-positioned products. Evidence for applied biotin changing hair growth is limited.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Unhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.
An acid used to set pH and, in scalp products, to loosen flakes.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
A humectant moves water in whichever direction the air allows: it holds moisture in humid conditions and can pull it back out of hair in very dry ones.
A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
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.
A fast-evaporating alcohol used as a solvent and to speed drying. Well down the list it is a processing aid; near the top it can leave hair feeling dry.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
A light humectant and carrier that helps extracts dissolve.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Light and water-binding rather than oily, so it hydrates without contributing weight.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
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.
A corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Light and water-binding rather than oily, so it hydrates without contributing weight.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
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.
A liquid fatty alcohol used for slip and to keep a formula fluid.
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 waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
A conditioning agent used for slip in thick creams and masks.
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 cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
A conditioning silicone that binds where hair is damaged, for smoothing and heat protection.
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 surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
A wax that gives shampoo its pearly look and a slightly richer feel.
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 conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.
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 conditioning polymer that improves wet combing and adds body. Repeated use can build up on fine hair.
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-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.
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.
Grabs metal ions from hard water so they cannot dull the 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.
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.
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.
A soft floral fragrance component listed separately as a recognised 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.

Formula
The formula carries what a shampoo is built around, and 5 products we score as close matches cost at least a quarter less per ounce. The difference is buying the label, not a different formula.
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.
