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.
Gums and synthetic polymers together.
Film formers with little to soften them, so expect a cast to scrunch out.
Water-first and light: unlikely to flatten fine hair.
Absorbents appear, low in the list.
No oils or butters in the list.
No fast-drying alcohol in the list.
Nothing here needs a detergent wash to remove.
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.
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.
Keeps fragrance and oils dissolved in a watery formula so it stays clear.
Listed in the first three ingredients, it is likely a structural part of this formula.
A hold polymer that dries to a clear film. It sets the style and washes out with water.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
An amaranth seed extract used at low levels for moisture and shine claims.
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.
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
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.
An extract from the seed of Carob (Ceratonia Siliqua). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A plant protein used for body and moisture retention.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 starch that soaks up oil at the roots and adds texture.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Adds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.
Starch gives texture and grip rather than a set film; firm hold usually needs a polymer alongside it.
A hold polymer common in hairsprays and mousses; it sets without much stiffness.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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 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 conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.
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.
A conditioning polymer that improves wet combing and adds body. Repeated use can build up on fine hair.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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 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.
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.
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.
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 clove-scented 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.
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 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.

A synthetic musk or woody-amber note used as a fragrance base.
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.
The essential oil of Eucalyptus Globulus. Essential oils are aromatic — they are in the formula for scent, and they are a common source of declared fragrance allergens.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.
The essential oil of Citrus Aurantium. Essential oils are aromatic — they are in the formula for scent, and they are a common source of declared fragrance allergens.
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 pine-scented component of essential oils, declared as part of the fragrance.
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 mint- or caraway-scented fragrance component.
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 lavender-like fragrance component, related to linalool and listed for the same allergen reason.
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.
An individual aroma chemical. It is part of the product's fragrance; brands that print these are disclosing more of the blend than the rules require.
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 lilac-like fragrance component found naturally in several essential oils.

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.
Instantly thicker, fuller-looking hair
Density and growth are cosmetic claims an ingredient list cannot settle.
Not something a label can show.
Fuller-looking hair with no sticky or crunchy feel
Hold polymers appear without the emollients that usually keep a film from setting firm.
Expect a cast you have to scrunch out.
Helps protect hair from heat damage up to 450°F/232°C
Heat protection is a performance claim; an ingredient list cannot confirm it.
Only lab testing can show this.
Up to 1.7x more volume that lasts all day
A brand-run study. We report it as stated and do not repeat the number as fact.
