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.

Shine system Silicone serum

A silicone or oil blend does the shine work here.

Weight on the hair Medium

Middle of the range: noticeable on fine hair, light on coarse hair.

Oils and butters Present, high in the list

Oils sit high in the list: a softening, coating formula.

Needs detergent to remove Yes

Water-insoluble silicones or waxes: a detergent wash is what removes them.

Fast-drying alcohol None

No fast-drying alcohol in the list.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

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 (32)

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 Cyclopentasiloxane
    General function

    A light, fast-evaporating silicone that spreads other ingredients then leaves. It gives serums their weightless glide.

    Leading ingredient

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

    May suitBuild-up-sensitive routines

    It leaves the hair by evaporating rather than by being washed off, so it is not part of what accumulates.

    May suitClimate-sensitive or frizz-prone hair

    A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

    May suitFine or easily flattened hair

    A cyclic silicone evaporates after it has spread the formula, so it carries the other ingredients without leaving weight behind.

    PubChem
    • silicone
    • emollient
  • 2 Dimethiconol
    General function

    A high-shine silicone often paired with dimethicone for a smoother, glossier finish.

    Leading ingredient

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

    May suitClimate-sensitive or frizz-prone hair

    A 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 hair

    Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

    May not suitBuild-up-sensitive routines

    Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.

    PubChem
    • silicone
    • emollient
  • 3 Keratin Amino Acids
    General function

    Keratin broken all the way down to individual amino acids. Small enough to sit inside the cuticle, used for softness rather than firmness.

    Leading ingredient

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

    May suitVery dry or highly damaged hair

    Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

    DependsProtein-sensitive hair

    The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

    • protein
    • amino acid
  • 4 Cocoyl Hydrolyzed Keratin
    General function

    A protein given a positive charge so it deposits where hair is damaged. It conditions and adds temporary firmness in one ingredient.

    Supporting ingredient

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

    • film former
    • protein
    • hydrolysed protein
  • 5 Cocoyl Hydrolyzed Collagen

    • cleanser
  • ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
  • 6 Tocopherol
    General function

    Vitamin E. It keeps the oils in a formula from going rancid and is used at very low levels.

    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.

    PubChem
    • antioxidant
    • vitamin
  • 7 Sesamum Indicum (Sesame) Seed Oil
    General function

    A medium-weight oil used for conditioning and scalp application.

    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

    Coats 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 hair

    A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

    • oil
    • emollient
  • 8 Hydroxypropyltrimonium Hydrolyzed Rice Protein/Siloxysilicate
    General function

    A protein given a positive charge so it deposits where hair is damaged. It conditions and adds temporary firmness in one ingredient.

    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 suitFrizz-prone, damaged, or high-friction hair

    A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

    May suitMaximum-hold styling

    Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

    May suitVery dry or highly damaged hair

    Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.

  • 11 Lecithin
    General function

    A soy- or sunflower-derived lipid that helps conditioning ingredients spread evenly on the strand.

    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 suitFrizz-prone, damaged, or high-friction hair

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

    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

    Coats 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 hair

    A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

    • oil
    • emollient
  • 19 Triethanolamine
    General function

    A base used in trace amounts to neutralise acidic polymers so a gel thickens.

    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.

    DependsFrizz-prone, damaged, or high-friction hair

    pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

    PubChem
    • pH adjuster
  • 20 Leuconostoc/Radish Root Ferment Filtrate
    • preservative
  • 21 Populus Tremuloides Bark Extract
    • botanical extract
  • 22 Butylene Glycol
    General function

    A light humectant and carrier that helps extracts dissolve.

    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 suitFine or easily flattened hair

    Light and water-binding rather than oily, so it adds less weight than oils or butters do.

    May suitVery dry or highly damaged hair

    A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

    DependsClimate-sensitive or frizz-prone hair

    A 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.

    PubChem
    • humectant
    • solvent
  • 23 Phenoxyethanol
    • preservative
  • 24 Ethylhexylglycerin
    General function

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

    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 suitFrizz-prone, damaged, or high-friction hair

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

    PubChem
    • preservative
    • emollient
  • 25 Fragrance · Parfum/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.

    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

    Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

    • fragrance
    • declared fragrance
  • 26 Benzyl Alcohol

How we work this out
  1. 0.63 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 $3.75 is the price we have observed for the 0.63 oz. We need three stores before we call a price commonly seen.
  3. Good value under $3 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $4.48/oz; at 0.63 oz that is $3. Under that line you are paying less than most of them.
  4. About $5 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 0.63 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.

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.

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.

Used daily focused on the ends; absorbs quickly and doesn't leave a greasy residue, with a scent that lasts.

reviewer applying to hair ends

Effective at working out tangles and knots in dry, damaged hair.

reviewer with dry/damaged hair

Good value for the price, leaves hair smooth and shiny without weighing it down.

general reviewer

The scent is noticeable but not overpowering or long-lingering, the vial packaging is mess-free and easy to dose, and the oil feels light rather than greasy or heavy on hair.

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.
  • 6 sources consulted for this product (1 manufacturer or regulatory, 4 retailer, 1 editorial), last checked 2026-08-27.
  • Ingredient references are linked for 12 of 17 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.
