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 are present, lower in the list.
Humectants near the top — water-binding is a headline mechanism here.
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 high in the list — a strengthening formula, not a moisture one.
No fragrance is listed.

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 strong non-sulfate detergent used in "sulfate-free" shampoos. It cleans about as thoroughly as a sulfate despite the label difference.
Listed in the first three ingredients, it is likely a structural part of this formula.
A strong detergent with no sulfate on the label. It removes deposited films about as completely as a sulfate does.
Sulfate-free on the label is a naming fact, not a mildness one: this is an efficient detergent, and hair short of moisture can feel 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 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.
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 sugar-derived, low-foam cleanser used in gentle and curly-method shampoos.
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.
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.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 mild cleanser that keeps foaming in hard water and rinses cleanly.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
An animal-derived protein used for body and a smoother surface feel.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A large water-binding molecule that sits on the surface holding moisture.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Because it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
The exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.
A jojoba-derived wax that gives a soft, cushioned finish and light hold in balms.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.
Flaxseed oil, used for softness; the seed extract is used instead for natural hold.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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.
A heavy, coating oil traditionally used for deep conditioning.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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.
Not chemically an oil: about 97% of it is liquid wax esters, which is why it resists going rancid and sits close to the scalp's own sebum. It smooths without a heavy finish.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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.
A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.
A quinoa-derived protein used for light strengthening and colour retention claims.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.
A plant protein modified to bind more firmly to hair than a plain hydrolysed protein. Used for strength and body claims.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
A sugar-derived conditioning agent used in bond-repair positioned formulas for moisture and slip.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
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.
A sugar-derived conditioning agent with a positive charge, used alongside hydroxypropylgluconamide.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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 guar-bean conditioning polymer that deposits during rinsing. It is why a strong shampoo can still leave hair combable.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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.
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 positively charged conditioning agent. Damaged hair carries a negative charge, so it deposits where the damage is and makes wet hair comb through.
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 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 hold polymer that forms a firm, humidity-resistant film. It is the usual source of a hard cast in gels.
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 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 coconut-derived thickener that stabilises shampoo foam and gives the liquid its body.
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.
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 fruit acid used to set an acidic pH; at higher levels it also loosens surface build-up.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.
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 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 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.
A mild cleanser built on a coconut- or plant-derived fatty acid. Cleansers of this family lather less aggressively than a sulfate and leave hair less stripped.
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 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 biodegradable hard-water chelator used in place of EDTA.
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.
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.

Reviewers
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
Many reviewers value that it is fragrance-free and say it leaves hair soft and clean without stripping it out.
A number of reviewers report the opposite effect — dry, straw-like or crunchy hair after using it.
Several reviewers describe a strange residue, clumping or tangling left in hair after shampooing.
A few reviewers warn of protein or product buildup leading to hair breakage with regular use, urging frequent clarifying.
