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.
Some slip, mostly from esters or silicones rather than conditioners.
Oils are present, but low enough to be a finishing touch.
Water-first and light: unlikely to flatten fine hair.
Humectants near the top: binding water is one of its main jobs.
Protein appears, low enough to be a supporting ingredient.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Contains chelators, which bind hard-water and pool minerals.
No fragrance is listed.
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.
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 corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.
Listed in the first three ingredients, it is likely a structural part of this formula.
Light and water-binding rather than oily, so it adds less weight than oils or butters do.
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.
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Listed in the first three ingredients, it is likely a structural part of this formula.
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 humectant that also helps preserve the formula, often used where a brand wants a short preservative 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.
Light and water-binding rather than oily, so it adds less weight than oils or butters do.
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 sugar-beet derived humectant that binds water. Despite the name it is not a cleanser like cocamidopropyl betaine.
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 plant-derived light ester used where a silicone-free but silky feel is wanted.
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 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.
Included in scalp and thickening products for label appeal. Evidence for applied caffeine 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.
A copper-bound peptide used at low levels in scalp and thinning-positioned formulas.
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.
Vitamin B3, used in scalp products for conditioning 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.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
A synthetic film-forming polymer. Polymers of this kind dry to a continuous film on the hair, which is how a styling product holds a shape.
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.
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.
A light, refined coconut-derived oil that spreads easily and does not go rancid. It gives slip without a heavy 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.
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 very stable oil that forms a light, non-greasy protective layer.
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.
A thickener that turns a liquid into a clear gel. It also contributes a light 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.
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.
The oil pressed from Hippophae Rhamnoides. How much weight a plant oil leaves depends on the hair it lands on; coarse hair tends to take more of it than 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.
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 readily biodegradable chelator used in place of EDTA to bind hard-water minerals.
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 plant or fermented gum. Gums thicken a water-based formula and give it a slippery, cushioned feel; in a styler they also contribute soft 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.
A fermented sugar gum that thickens water-based formulas and adds soft, 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.
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 helps flyaways lie down.
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.
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 dry-feeling ester used for a silky, non-greasy finish - a common silicone substitute.
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 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.
The smallest amino acid in hair protein, added for moisture binding.
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.
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.
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.
A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.
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 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 colour added to tint the product itself. It does not colour 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.
A violet or blue colorant sits opposite yellow on the colour wheel, so a trace of it deposited on the surface makes a warm cast read cooler. It washes out over the following few washes.

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.
