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.
Conditioning agents are present, lower in the list.
Humectants in the working part of the formula.
Butters near the top: a heavy, softening formula.
Protein high in the list — a strengthening formula, not a moisture one.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No fragrance is listed.
Ingredients that matter
The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.
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.
Babassu oil - solid at cool temperatures, lighter than coconut oil in feel.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
Murumuru butter - very rich, used for sealing coarse or coily hair.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
The gum protein that coats raw silk fibres. It forms a smooth film and is used for shine and slip. Animal-derived.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
A large surface-depositing protein. If protein reliably makes your hair feel rigid, this is the form most likely to do it.
Not chemically an oil: about 97% of it is liquid wax esters, which is why it resists going rancid and sits close to the scalp's own sebum. It smooths without a heavy finish.
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.
A wax holds by staying solid on the strand, which gives grip and separation rather than a set film that cracks.
Green tea extract, included for antioxidants and as a marketing-forward botanical.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
An extract from the seed of Pea (Pisum Sativum). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
A plant-oil wax used as a vegan alternative to beeswax for hold and sheen.
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.
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
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.
A quinoa-derived protein used for light strengthening and colour retention 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.
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 positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.
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.
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
Every detergent removes some sebum along with the product it is there to wash out. Which detergent it is matters more than that there is one.
A styling polymer chosen for a soft, brushable 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.
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 conditioning polymer that improves wet combing and adds body. Repeated use can build up on fine hair.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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 small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.
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.
A large water-binding molecule that sits on the surface holding 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.
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 conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.
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.
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 coconut-derived preservative booster that also binds trace metals.
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.
A light humectant and carrier that helps extracts dissolve.
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 hydrates without contributing weight.
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 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 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.
Used with citric acid to hold the formula at a steady, slightly acidic pH. It also binds a little hard-water mineral.
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.
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 preservative booster that also holds a little moisture and helps other ingredients dissolve.
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 hydrates without contributing weight.
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 rose-scented alcohol that acts as both a mild preservative and a fragrance 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 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.

Formula
Above the range for leave-ins per ounce, on a formula that covers the middle of the format and has no close, cheaper equivalent in our library.
The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Final decision
People sensitive to fragrance who want a formula with no added fragrance and protein high in the formula
Not ideal for hair that stiffens on protein, oily scalps and fine hair, or anyone stretching time between washes

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 only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.
anti-frizz
Silicones or film formers smooth the cuticle, which is the usual mechanism.
Smoother strands, less frizz.
curl definition
Film formers or natural gums are present, which is what holds a clump together.
Holds a clump together.
UV protection
Antioxidants are present, which is not the same as a UV filter.
Indirect help, not a filter.
heat protection to 450F
Heat protection is a performance claim; an ingredient list cannot confirm it.
Only lab testing can show this.
glossy finish
The formula carries a recognised shine system — silicone, oil, or light ester.
Reflects light for visible shine.
We look at the first 10–15 ingredients and what they do in a formula — not marketing. If the list doesn't speak to a claim, we don't assume.
Reviewers
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
Multiple reviewers note the pump dispenses very little product, so thick or long hair needs many pumps to cover.
Several reviewers with fine or high-porosity hair report the treatment weighs curls down and leaves them limp rather than defined.
Many reviewers say it noticeably reduces frizz and helps curls hold definition in humid or hot weather.
A recurring complaint is a strong or unpleasant fragrance that some reviewers say pushed them back to other Ouidad products.
