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.
A silicone or oil blend does the shine work here.
Middle of the range — noticeable on fine hair, light on coarse hair.
No oils or butters in the list.
The brand claims humidity resistance; the ingredient list cannot confirm it.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
No fast-drying alcohol in the list.
Fragrance sits in the first eight ingredients — a larger share of the formula.

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
Dimethicone
General function
The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitClimate-sensitive or frizz-prone hairA 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 hairLays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
May not suitBuild-up-sensitive routinesDimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.

- emollient
- conditioning agent

Bis-(Morpholinomethyl C1-4 Dialkoxysiloxy) Dimethicone
General function
A silicone. Silicones coat the strand for slip, shine and frizz control; unless the name carries PEG or PPG, removing one takes a detergent rather than water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.

- conditioning agent

Bis-Cetearyl Amodimethicone
General function
A conditioning silicone that deposits selectively on damaged hair for slip and shine.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitClimate-sensitive or frizz-prone hairA 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 hairAmino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

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.

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
- 17 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 $30 is the price we have observed for the 17 oz. We need three stores before we call a price commonly seen.
- Good value under $36 comes from the 5 products we score as doing the same job as this one. A quarter of them cost less than $2.14/oz; at 17 oz that is $36. Under that line you are paying less than most of them.
- About $54 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 17 oz.
Formula
It carries the working systems a anti-frizz finisher needs and still sits in the lower part of the price range for anti-frizz finishers per ounce.
How the score is counted
- Costs less per ounce than 100% of the 22 anti-frizz finishers we’ve priced
- Covers 4 of the 6 things a anti-frizz finisher should do
- Reviewers mention 3 things they like about how it performs
- Salon tier, sold at Ulta and Brand website
- A shine systemThe silicone, oil, or ester that produces gloss.3 pts
- A weightless carrierDelivers the shine without leaving grease.2 pts
- Oils or butters in the working zoneSoftens the strand rather than just coating it.2 pts
- An antioxidantKeeps the oils in the bottle from going off.1 pt
- No drying alcohol in the first threeFast drying without leading on alcohol.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
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.

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.
- 2 sources consulted for this product (1 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-09-04.
- Ingredient references are linked for 3 of 7 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 2026-09-04.
