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.
Middle of the range: noticeable on fine hair, light on coarse hair.
Conditioning agents are present, lower in the list.
Humectants in the working part of the formula.
No oils or butters in the list.
Protein high in the list: a strengthening formula, not a moisture one.
Sold as a heat protectant; no temperature is stated.
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.
A water-soluble silicone that smooths without the build-up concern of standard silicones.
Listed in the first three ingredients, it is likely a structural part of this formula.
The PEG- and PPG-modified silicones disperse in water, so ordinary washing carries them off instead of leaving a film to accumulate.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Delivers the slip and surface smoothing of a silicone without needing a detergent wash to remove it afterwards.
Fragments of the same protein hair is made of. They fill gaps on damaged strands and make hair feel firmer for a few washes.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
Size decides where it goes. In fibre testing, fractions around 221 and 2,577 Da reached the cortex while a 75,440 Da fraction stayed on the surface. A label prints the name, never the size, so a protein line is a claim about the ingredient rather than about the depth.
A light protein used for slip and shine rather than strength.
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.
Roman chamomile extract, used at low levels for a soothing claim.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Lavender extract, used at low levels for scent association and a calming claim.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Peppermint leaf extract, used for scent association and a cooling claim.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
An extract of Clary (Salvia Sclarea). 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.
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.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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 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.
A conditioning silicone with a positive charge, so it deposits where hair is damaged and stays through rinsing.
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 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.
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 solvent that keeps other ingredients dissolved and helps preservatives work.
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 fine mineral powder that absorbs oil and adds grip. It is what makes texture powders and matte pastes feel dry to the touch.
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 dry powder takes up oil and adds friction between strands, which is most of what root lift in fine hair actually is.
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 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.
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 rose-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 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 white mineral pigment that makes a product opaque or pearly.
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.
A certified colour added to tint the product itself. It does not colour hair.

Price · 12 oz
Usually a good value. Most stores sell it under the $26 line, and products that do this job typically go for about $46 at this size.
Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.
Formula
Both the formula and the price land mid-range: it covers the core of what a leave-in does and costs about what leave-ins cost per ounce.
The formula score measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.
Does the same job
Formulas that do the same things (cleanse, condition, coat or hold) for less per ounce. Scent, texture and where you buy them can still differ.

Final decision
People who blow-dry or flat-iron who want heat protection and protein high in the formula
Worth skipping for anyone sensitive to fragrance, curly-method routines, or hair that stiffens on protein
Nothing in our library matches it closely at a lower price.
We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.
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.
