What the formula actually does
Read from the label, not the marketing
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 near the top: binding water is one of its main jobs.
Oils sit high in the list: a softening, coating formula.
Protein appears, low enough to be a supporting ingredient.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Fragrance is listed; it sits below the working ingredients.

Full ingredient list (32)
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.

Water
· Water (Aqua, Eau)
General function
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent
-
2
Panthenol
General function
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.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitFine or easily flattened hairIt hydrates without adding oil or a film, which is the combination fine hair usually needs.
May suitFrizz-prone, damaged, or high-friction hairDeposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
May suitVery dry or highly damaged hairA humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

Prunus Insititia Seed Oil
General function
The oil pressed from Prunus Insititia. How much weight a plant oil leaves depends on the hair it lands on; coarse hair tends to take more of it than fine hair.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitDry, coarse, or high-porosity hairCoats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
May suitFrizz-prone, damaged, or high-friction hairA thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

Simmondsia Chinensis (Jojoba) Seed Oil
General function
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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

General function
A concentrated aloe extract used for light moisture and a soothing claim.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitFine or easily flattened hairHydration with no oil attached, so it adds very little weight even high on a list.

Hydrolyzed Vegetable Protein PG-Propyl Silanetriol

A plant protein modified to bind more firmly to hair than a plain hydrolysed protein. Used for strength and body claims.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitFrizz-prone, damaged, or high-friction hairFilling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
May suitBuild-up-sensitive routinesThe PEG- and PPG-modified silicones disperse in water, so ordinary washing carries them off instead of leaving a film to accumulate.

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.
How we work this out
- 5.1 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
- Commonly seen is the middle half of current prices for the 5.1 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- Good value under $25 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $4.93/oz; at 5.1 oz that is $25. Under that line you are paying less than most of them.
- About $30 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 5.1 oz.
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.
How the score is counted
- 1 products we score as doing the same job cost less per ounce
- Costs more per ounce than 68% of the 749 leave-ins we’ve priced
- No conditioning agents up front in the formula
- Reviewers mention 2 things they like about how it performs

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.

What people report
Themes that come up again and again in sourced reviews, written by our researchers in their own words. We don’t store or scrape star ratings.
Many reviewers say it makes wet hair easy to detangle, including knotted or curly hair.
Reviewers with curly or damaged hairMany reviewers say the spray leaves hair softer and shinier without a heavy feel.
Reviewers across hair typesSome reviewers wish it provided more moisture or body, feeling it is too thin.
Reviewers with fine or very dry hairMany reviewers like the light, fresh scent, though some find it faint or odd as it dries.
Reviewers across hair typesSome reviewers say it feels sticky or heavy, especially when they use too much product.

How this page was made
- Everything above comes from our researched product record: identity, the ingredient list as printed, the brand's own claims, dated prices and review themes our researchers wrote in their own words. No part of this page is written by hand for one product.
- The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
- Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
- The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
- 3 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-10-31.
- Ingredient references are linked for 10 of 22 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
- We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
- Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
- Formula readings: derivation v23. Record last updated 2026-10-07.
