Removes oil, sweat, odors and buildup
The detergent system is gentle; it is unlikely to clear heavy build-up on its own.

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.
Cleansing strength
None
No detergent. The conditioners do the cleaning.
Expected lather
Little
Very little foam; it is worked through rather than lathered.
Slip and detangling
Some
Some slip, mostly from esters or silicones rather than conditioners.
Water-binding (humectants)
Moderate
Humectants in the working part of the formula.
Scalp active
None
No over-the-counter scalp active.
Hard-water defence
None
No chelating agent in the list.
Needs detergent to remove
No
Nothing here needs a detergent wash to remove.
Protein
None
No protein or amino acids in the list.
Fragrance
Prominent
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

Ingredients that matter
The ingredients that change a decision
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.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| Alcohol Denat. | drying alcohol | Speeds drying but can leave hair feeling dry | Drying |
| WaterWater (Aqua) (Eau) | solvent | The base everything else is dissolved in | Neutral |
| Tapioca Starch | starch | Soaks up oil and adds grip | Neutral |
| Ammonium Polyacryloyldimethyl Taurate | thickener | Sets the texture | Holds |
| Triheptanoin | light ester | Light slip without much weight | Softens |
| C13-16 Isoalkane | emollient | Softens and smooths the strand | Softens |
| Rosmarinus Officinalis (Rosemary) Leaf Oil | botanical extract | A trace plant extract | Fragrance |

| Alcohol Denat.Alcohol | drying alcohol | A small amount, for fast drying | Drying |
What the list leaves out, and what it carriesThe list carries no sulfates or silicones. No protein: a moisture formula, not a repair one. Fragrance is on the label. Contains fast-drying alcohol.
Full ingredient list (30)
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
Alcohol Denat.
General function
Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitFine or easily flattened hairEvaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
May not suitDry, coarse, or high-porosity hairPorous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.
May not suitVery dry or highly damaged hairIt evaporates quickly and takes some water with it. On hair already short of moisture, a formula built on a lot of it can finish drier than it started.

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.

3
Tapioca Starch
General function
A fine starch that absorbs oil and leaves a dry, grippy feel.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitFine or easily flattened hairAdds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.
DependsMaximum-hold stylingStarch gives texture and grip rather than a set film; firm hold usually needs a polymer alongside it.
- starch
- powder

4
Ammonium Polyacryloyldimethyl Taurate
General function
A synthetic thickener that gels water quickly and holds oils in suspension. It gives creams a light, springy texture.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
- thickener
- polymer
-
5
Triheptanoin
General function
A light plant-derived ester used for slip and a non-greasy finish.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay 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
-
6
C13-16 Isoalkane
General function
A branched hydrocarbon of the stated chain length. It spreads other ingredients thinly and evaporates, leaving the hair without added weight.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
- emollient
- solvent

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
- 7.1 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 7.1 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 $45 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $6.35/oz; at 7.1 oz that is $45. Under that line you are paying less than most of them.
- About $54 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 7.1 oz.

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.
- 5 sources consulted for this product (2 manufacturer or regulatory, 2 retailer, 1 editorial), last checked 2026-10-17.
- Ingredient references are linked for 9 of 18 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 2026-10-17.
