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.

Slip and detangling Some

Some slip, mostly from esters or silicones rather than conditioners.

Oils and butters None

No oils or butters in the list.

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Needs detergent to remove Rinses with water

The silicones here are the water-soluble kind.

Ingredients that matter

The ingredients that change a decision

The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

Full ingredient list (9)

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

  • 1 Pyrithione Zinc (0.1%)
  • 2 Alcohol Denat. · Ethanol
    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 ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    May suitFine or easily flattened hair

    Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.

    May not suitDry, coarse, or high-porosity hair

    Porous 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 hair

    It 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.

    PubChem
    • drying alcohol
    • solvent
  • 3 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 ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    • solvent
  • 4 Niacinamide
    General function

    Vitamin B3, used in scalp products for conditioning claims.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    May suitFrizz-prone, damaged, or high-friction hair

    Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

    PubChem
    • vitamin
    • conditioning agent
  • 5 Peg/Ppg-20/23 Dimethicone
    General function

    An ethoxylated or propoxylated formulation aid. Ingredients of this family keep oils, silicones and fragrance evenly dispersed in a water-based product.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    • emulsifier
    • silicone
    • water-soluble silicone
  • 6 Glycerin
    General function

    A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    May suitDry, coarse, or high-porosity hair

    High-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 hair

    Binds 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 hair

    Water 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.

    Scientific Reports
    • humectant
  • 7 Acrylates/C10-30 Alkyl Acrylate Crosspolymer
    General function

    A gel-forming thickener that also keeps oils suspended. It contributes a little hold.

    Supporting ingredient

    Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

    May suitClimate-sensitive or frizz-prone hair

    A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

    May suitMaximum-hold styling

    Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

    DependsBuild-up-sensitive routines

    Some 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
  • ▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 8 Mentha Piperita (Peppermint) Oil
    General function

    Peppermint essential oil, used for scent and the cooling feeling on the scalp.

    Estimated lower-concentration zone

    It 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 routines

    Essential 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.

    • botanical extract
    • essential oil
    • fragrance
  • 9 Tetrahydroxypropyl Ethylenediamine

What the whole list adds up to

  • 2 solvents
  • 1 drying alcohol
  • 1 vitamin
  • 1 conditioning agent
  • 1 emulsifier
  • 1 silicone
  • 1 water-soluble silicone
  • 1 humectant

Where we’ve seen it1 listing · 1 store

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
  1. 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.
  2. Seen at $12.97 is the price we have observed for the 4.2 oz. We need three stores before we call a price commonly seen.
  3. Good value under $23 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $5.58/oz; at 4.2 oz that is $23. Under that line you are paying less than most of them.
  4. About $36 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 4.2 oz.

Formula

Low cost per ounce, with a short formula: there is no conditioning agents up front here, and that is a system most scalp treatments carry.

How the score is counted
  • 1 products that do the same job cost less per ounce
  • Costs less per ounce than 77% of the 152 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 is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.

Does the same job, for less

Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Claims check

What the brand says, against what the formula shows

Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

Reviewers

What people report

Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.

The pointed applicator tip is called out as making it easy to target itchy or flaky sections directly on the scalp, especially through thick hair.

reviewers with thick or hard-to-reach hair

Reviewers repeatedly praise the lightweight, non-greasy feel and how quickly it absorbs into the scalp without weighing hair down.

general reviewers using it between washes

The cooling, minty tingle on contact is a divisive sensory trait: most reviewers describe it as pleasant and soothing, but at least one disliked the menthol scent outright.

general reviewers

Some reviewers with very sensitive or dry scalps found it only okay, noting mild irritation, and said it soothes itch without visibly reducing dandruff itself.

How this page was made

  • Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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.
  • 6 sources consulted for this product (3 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-09-06.
  • Ingredient references are linked for 3 of 5 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
  • We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
  • 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 v22. Record last updated 2026-09-06.
