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.
Nothing here is built to reduce combing force.
Humectants near the top: binding water is one of its main jobs.
Oils sit high in the list: a softening, coating formula.
No protein or amino acids in the list.
Nothing here needs a detergent wash to remove.
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.
Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.
Listed in the first three ingredients, it is likely a structural part of this formula.
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.
A thick, tacky oil used for sealing ends and for slick, held-down styles.
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.
One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.
Listed in the first three ingredients, it is likely a structural part of this formula.
Because it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
The exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.
A plant or fermented gum. Gums thicken a water-based formula and give it a slippery, cushioned feel; in a styler they also contribute soft hold.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.
A cellulose thickener that gives gels and conditioners their body and adds a soft, flexible film.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
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 biodegradable hard-water chelator used in place of EDTA.
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.

Priced above the products that do the same job. Stores sell it above the $13 line; products that do this job typically go for about $15 at this size.

Formula
Nothing separates this from the middle of the range for leave-ins, on formula or on 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, for less
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
Hair that stiffens on protein, for a protein-free formula and moisture that stays in
Not ideal for anyone sensitive to fragrance, oily scalps and fine hair, or soft, over-stretchy hair that needs protein

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.
A light cream oil moisturizer used to refresh your hair days after your style.
Humectants or rich emollients sit in the first eight ingredients.
Helps hair feel hydrated.
We look at the first 10–15 ingredients and what they do in a formula, not at the marketing. If the list doesn't speak to a claim, we don't assume.
