Whether this much richness suits you depends on your strand thickness, porosity and how easily your hair goes flat. We work that out in the consultation.

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 Little

Nothing here is built to reduce combing force.

Oils and butters None

No oils or butters in the list.

Weight on the hair Light

Water-first and light: unlikely to flatten fine hair.

Water-binding (humectants) High

Humectants near the top: binding water is one of its main jobs.

Protein None

No protein or amino acids in the list.

Needs detergent to remove No

Nothing here needs a detergent wash to remove.

Hard-water defence None

No chelating agent 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.

Full ingredient list (11)

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 · Aqua
    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
  • 2 Hamamelis Virginiana Extract · Hamamelis Virginiana (Witch Hazel) Extract
    General function

    An extract of Hamamelis Virginiana. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Leading ingredient

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

    • botanical extract
  • 3 Aloe Barbadensis Leaf Juice · Organic Aloe Barbadensis (Aloe Vera) Juice
    General function

    Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.

    Leading ingredient

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

    May suitCurls or waves needing flexible hold

    Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

    May suitFine or easily flattened hair

    Hydration with no oil attached, so it adds very little weight even high on a list.

    May suitVery dry or highly damaged hair

    Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.

    • humectant
    • botanical extract
    • gum
  • 4 Organic Cucumis Sativus (Cucumber) Fruit Extract
    General function

    An extract from the fruit of Organic Cucumis. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Supporting ingredient

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

    • botanical extract
  • 5 Coco-Glucoside · Coco Glucoside
    General function

    A sugar-derived, low-foaming cleanser used in gentle and curly-method shampoos.

    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

    Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

    May suitVery dry or highly damaged hair

    A 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 routines

    Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.

    PubChem
    • nonionic cleanser
    • cleanser
  • 6 Ilex Guayusa Leaf Extract
    General function

    An extract from the leaf of Ilex Guayusa. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Supporting ingredient

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

    • botanical extract
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 7 Chlorophyll
    General function

    A natural plant pigment (commonly from grass, alfalfa or nettles) used as a green colorant in gels, mousses and treatments.

    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.

    • colourant
  • 8 Fragrance (Aroma) · Natural Aroma
    • fragrance
    • declared fragrance
  • 9 Glycerin · Vegetable Glycerin
    General function

    Glycerin, also called glycerol, attracts moisture and mixes completely with water.

    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 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
  • 10 Potassium Sorbate
    • preservative
  • 11 Citric Acid
    General function

    Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

    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 suitBuild-up-sensitive routines

    Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

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

    The acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.

    May suitGray, silver, or brass-prone hair

    Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

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 $36 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 $14 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $3.39/oz; at 4.2 oz that is $14. Under that line you are paying less than most of them.
  4. About $16 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 4.2 oz.

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 person
Best user

Hair that stiffens on protein, for a protein-free formula and something that will not weigh hair down

Biggest tradeoff

Not ideal for anyone sensitive to fragrance, very dry or very humid climates, or people shopping on a budget

Best alternative if not

Consider Rizos Curls Apple Cider Vinegar Scalp & Hair Rinse, for similar results at a lower price

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.
  • 4 sources consulted for this product (0 manufacturer or regulatory, 1 retailer, 3 editorial), last checked 2026-09-15.
  • Ingredient references are linked for 3 of 4 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 2026-09-15.
