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.
A silicone or oil blend does the shine work here.
Water-first and light: unlikely to flatten fine hair.
No oils or butters in the list.
No humidity claim on the label.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No fast-drying alcohol in the list.
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.
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 castor-oil derivative that dissolves fragrance and oils into water so the product stays clear and does not separate.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
Listed in the first three ingredients, it is likely a structural part of this 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.
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.
The most common modern preservative; it keeps the product free of bacteria and mould. It sits well below 1% of 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.
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 cellulose thickener that gives gels and conditioners their body and adds a soft, flexible film.
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.
A fermented gum that thickens and gives a slippery, cushioned 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 modified guar gum used to thicken and give a slippery, cushioned 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.
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.
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.
A silicone. Silicones coat the strand for slip, shine and frizz control; unless the name carries PEG or PPG, removing one takes a detergent rather than 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.
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 gentle conditioning agent activated by the acid in the formula. It smooths the cuticle without much 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.
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.
An acid used to set pH and, in scalp products, to loosen flakes.
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 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.
A floral fragrance component listed separately as a recognised contact 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 UV filter used in leave-on hair products to slow colour fade.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Sunlight oxidises hair pigment, and on gray, silver or lightened hair that shows up as yellowing. A UV filter on the label absorbs some of the light that drives it.
A soft floral 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.
The smallest fruit acid, used in scalp products to loosen flakes and clear 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 fragrance component with a faint balsamic scent, named separately on the label because it is a recognised contact 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.
