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. 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 (32)

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 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 Phenyl Trimethicone
    General function

    A high-refractive silicone used specifically for visible shine in serums and finishing oils.

    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.

    • silicone
    • emollient
  • 4 Ethylhexyl Methoxycinnamate
    General function

    A UV filter added to protect the product's colour and, in leave-ins, to slow colour fade.

    Supporting ingredient

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

    May suitGray, silver, or brass-prone hair

    Sunlight oxidises hair pigment, and on gray, silver or lightened hair that shows up as yellowing. A UV filter on the label absorbs some of the light that drives it.

    PubChem
    • UV filter
  • 5 Olea Europaea (Olive) Fruit Oil
    General function

    A heavy, coating oil traditionally used for deep conditioning.

    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

    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.

    May not suitFine or easily flattened hair

    Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.

    • oil
    • emollient
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 6 Tocopheryl Acetate · Tocopheryl (Vitamin E) Acetate
    General function

    A stable form of vitamin E used to keep the oils in a formula from oxidising. It is used at fractions of a percent.

    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 Lavandula Angustifolia (Lavender) Oil
    General function

    Lavender essential oil, used for scent in aromatherapy-positioned products.

    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
  • 8 Gardenia Taitensis Flower Extract
    General function

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

    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.

    • botanical extract
  • 9 Cocos Nucifera (Coconut) Oil · Cocos Nucifera Oil
    General function

    One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.

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

    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

    Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

    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.

    General function

    A small humectant and solvent that keeps formulas stable and helps active ingredients spread.

    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 hydrates without contributing weight.

    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
  • 27 Fragrance · Fragrance (Parfum)
    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

How we work this out
  1. 6 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 $16.78 is the price we have observed for the 6 oz. We need three stores before we call a price commonly seen.
  3. Good value under $60 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $10.00/oz; at 6 oz that is $60. Under that line you are paying less than most of them.
  4. About $71 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 6 oz.

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.

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 (0 manufacturer or regulatory, 5 retailer, 1 editorial), last checked 2026-09-05.
  • Ingredient references are linked for 9 of 15 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 2026-09-05.
