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.
Conditioning agents sit high in the list, so this is a detangling formula.
No oils or butters in the list.
Middle of the range: noticeable on fine hair, light on coarse hair.
Humectants appear, but low enough to be a minor part.
No protein or amino acids in the list.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No chelating agent in the list.
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.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| Water | solvent | The base everything else is dissolved in | Neutral |
| Cetyl Alcohol | fatty alcohol | Thickens and conditions (not a drying alcohol) | Softens |
| Ethylhexyl Olivate | light ester | Light slip without much weight | Softens |
| Cetearyl Alcohol | fatty alcohol | Thickens and conditions (not a drying alcohol) | Softens |
| Quaternium-91 | conditioning agent | Conditions and softens so hair combs through | Detangles |
| Cetrimonium Methosulfate | conditioning agent | Conditions and softens so hair combs through | Detangles |
| Cetyl Esters | light ester | Light slip without much weight | Softens |
| Squalane | emollient | Softens and smooths the strand | Detangles |
| Amodimethicone | silicone | A little smoothing and shine | Buildup |
| Tribehenin | wax | Adds a little grip | Buildup |
| Dimethicone | silicone | A little smoothing and shine | Buildup |
| Alcohol Denat. | drying alcohol | A small amount, for fast drying | Drying |
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 fatty alcohol used to thicken creams and add slip. It softens rather than dries.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.
A light olive-derived ester used as a plant alternative to silicone slip.
Listed in the first three ingredients, it is likely a structural part of this 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 waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.
In conditioner, cetearyl alcohol gives the emulsion its creamy structure and helps it spread evenly through the hair. Its emollient layer adds slip and a smoother feel.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suit dry, coarse, or high-porosity hair that benefits from added slip and a more substantial conditioning film.
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
Consider if hair is fine or easily flattened: a formula built heavily around fatty alcohols can feel richer than a lightweight conditioner.
A conditioning agent used in leave-ins for detangling without much weight.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 positively charged conditioning agent. Damaged hair carries a negative charge, so it deposits where the damage is and makes wet hair comb through.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 waxy ester blend that replaces spermaceti in creams. It thickens and leaves a smooth, non-greasy finish.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 fully hydrogenated form of squalene, now made from olive or sugarcane rather than shark liver. Hydrogenation is what makes it so slow to oxidise; it spreads very lightly and absorbs without a greasy film.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
A positively charged conditioning agent. Damaged hair carries a negative charge, so it deposits where the damage is and makes wet hair comb through.
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 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.
A silicone modified to stick where hair is damaged, so it smooths selectively instead of coating everything. It resists rinsing more than plain dimethicone.
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 plant-derived wax used to thicken balms and give a firm, smooth 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 wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
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.
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.
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.
Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
A quick-acting conditioning agent that reduces static and combing force. It also helps keep the formula stable.
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 C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on 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.
Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
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.
Vinegar acid, used in tiny amounts to bring the formula to an acidic pH so the cuticle lies flat.
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 citrate ester used to stabilise fragrance and support the preservative system.
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.
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 synthetic musk used as a long-lasting fragrance base note.
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 jasmine-like fragrance component named 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.
