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.
Some slip, mostly from esters or silicones rather than conditioners.
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.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

Full ingredient list (19)
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.

1
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
Ethyl Macadamiate
General function
A light macadamia-derived ester used for a dry, silky finish.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.
May suitFrizz-prone, damaged, or high-friction hairSpreads thin and lowers friction between strands without the heaviness of a fixed oil.
- light ester
- emollient

Dipropylene Glycol
General function
A light humectant and solvent that helps fragrance and extracts dissolve evenly.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it adds less weight than oils or butters do.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
DependsClimate-sensitive or frizz-prone hairA 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.

- solvent

Olus Oil
· Olus Oil/Vegetable Oil
General function
The oil pressed from Olus. 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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
May not suitFine or easily flattened hairNear the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.

- emollient

Polysilicone-29
General function
A silicone network that leaves a longer-lasting smoothing film than plain dimethicone.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitClimate-sensitive or frizz-prone hairA surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
May suitFrizz-prone, damaged, or high-friction hairLays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
- silicone
- film former

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Scientific ReportsMay suitDry, coarse, or high-porosity hairHigh-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
May suitVery dry or highly damaged hairBinds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
DependsClimate-sensitive or frizz-prone hairWater 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.

Polyglyceryl-2 Dipolyhydroxystearate
General function
A plant-derived polyglycerol ester. It emulsifies without ethoxylation, which is why it turns up in formulas positioned as PEG-free, and leaves a soft feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

Fragrance
· Fragrance/Parfum
General function
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.

PubChemMay suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May suitVery dry or highly damaged hairA sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.
May not suitBuild-up-sensitive routinesGentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.

Glyceryl Oleate
General function
An emulsifier that also softens, often added to make a cleanser feel less stripping.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
May suitFrizz-prone, damaged, or high-friction hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Disodium EDTA
General function
Grabs metal ions from hard water so they cannot dull the hair or destabilise the formula.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
PubChemMay suitBuild-up-sensitive routinesBinds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.
May suitGray, silver, or brass-prone hairCopper 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.

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
- 6 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 6 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 $6 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $1.07/oz; at 6 oz that is $6. Under that line you are paying less than most of them.
- Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
- About $7 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 6 oz.
Formula
Above the range for leave-ins per ounce for a formula that 6 lower-priced products come close to on ingredients and attributes.
How the score is counted
- 6 products that do the same job cost less per ounce
- Costs more per ounce than 78% of the 749 leave-ins we’ve priced
- No conditioning agents up front in the formula

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.

Reviewers
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 the spray tames frizz and leaves hair looking shinier and smoother.
Reviewers across hair typesSeveral reviewers use it before heat styling and feel their hair is shielded from their tools.
Reviewers who heat style their hairSome reviewers say it is hard to style with, feels sticky, and gave poor styling results on coarse hair.
Reviewers with long, coarse hairReviewers disagree on weight, as some say it makes fine hair limp while others say it stays light.

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 (1 manufacturer or regulatory, 1 retailer, 1 editorial), last checked 2026-10-31.
- Ingredient references are linked for 10 of 15 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 2026-10-08.
