Full ingredient list (16)
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
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
Niacinamide
General function
Vitamin B3, used in scalp products for conditioning claims.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay 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.
- vitamin
- conditioning agent
-
3
PEG-40 Hydrogenated Castor Oil
General function
A castor-oil derivative that dissolves fragrance and oils into water so the product stays clear and does not separate.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solubilizer
- emulsifier
- ▾Below about here, the order stops meaning much. These are usually used at 1% or less.

Menthol
General function
Produces the cooling, tingling feeling on the scalp. The sensation is real; it is not evidence that anything else is happening.
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 not suitFragrance-sensitive routinesDeclared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

Mentha Piperita (Peppermint) Oil
General function
Peppermint essential oil, used for scent and the cooling feeling on the scalp.
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 not suitFragrance-sensitive routinesEssential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.

Mentha Arvensis Leaf Oil
General function
Cornmint oil, used for a cooling sensation and mint scent.
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.

Phenoxyethanol
General function
The most common modern preservative; it keeps the product free of bacteria and mould. It sits well below 1% of the formula.
Estimated lower-concentration zonePubChemIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

Caffeine
General function
Included in scalp and thickening products for label appeal. Evidence for applied caffeine changing hair growth is limited.

- silicone
- water-soluble silicone

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
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.
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.
- humectant

11
Fragrance
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.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer
General function
A gel-forming thickener that also keeps oils suspended. It contributes a little hold.
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 suitClimate-sensitive or frizz-prone hairA set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
May suitMaximum-hold stylingSynthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
DependsBuild-up-sensitive routinesSome acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
- thickener
- polymer
- film former

14
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.
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 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.

- vitamin
- 15 Tetrahydroxypropyl Ethylenediamine

Ethylhexylglycerin
General function
A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.
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 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.

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
- 4.2 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.
- Seen at $10.75 is the price we have observed for the 4.2 oz. We need three stores before we call a price commonly seen.
- Good value under $12 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.95/oz; at 4.2 oz that is $12. Under that line you are paying less than most of them.
- About $18 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 4.2 oz.

It costs less per ounce than most scalp treatments, and the formula leaves out conditioning agents up front, which a scalp treatment is usually built around.
How the score is counted

- Costs less per ounce than 86% of the 280 scalp treatments we’ve priced
- No conditioning agents up front in the formula
- No oils or butters in the working zone either

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
Should you buy it?
Good for the right personBest user
Hair that stiffens on protein who want a protein-free formula and something that will not weigh hair down
Biggest tradeoff
Less suited to anyone sensitive to fragrance, silicone-free routines, or vegan and cruelty-free shopping
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
What the brand says, and what the formula shows
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.

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 (1 manufacturer or regulatory, 2 retailer, 2 editorial), last checked 2026-09-09.
- Ingredient references are linked for 5 of 9 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.
