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.
Heavy butters and waxes in the first eight ingredients.
Some slip, mostly from esters or silicones rather than conditioners.
Humectants near the top: binding water is one of its main jobs.
Butters near the top: a heavy, softening formula.
Protein appears, low enough to be a supporting ingredient.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
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.
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 sugar-derived humectant that holds water with a lighter, satin feel rather than glycerin's tack. It also helps other ingredients stay dissolved.
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.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
A small humectant and solvent that keeps formulas stable and helps active ingredients spread.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 medium-weight oil used for softness and slip.
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.
A rich oil used in masks and heavier creams for softness on coarse or dry hair.
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.
A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
The oil pressed from Olive (Olea Europea). It is one of the heavier plant oils — rich on coarse or dry hair, and enough to flatten fine hair.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A light, fast-evaporating silicone that spreads other ingredients then leaves. It gives serums their weightless glide.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
It leaves the hair by evaporating rather than by being washed off, so it is not part of what accumulates.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
A cyclic silicone evaporates after it has spread the formula, so it carries the other ingredients without leaving weight behind.
The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.
A gentle preservative helper that also holds a little moisture.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
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.
Wheat protein broken into fragments small enough to cling to the hair. It adds temporary strength and body; too much can feel stiff.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
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.
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.
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.
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.
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.
