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.

Light esters
Light esters or a volatile carrier: shine with little residue.
Weight on the hair

Heavy butters and waxes in the first eight ingredients.

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.

Propylene Glycol Dibenzoate
General function
A light ester used for shine and slip in finishing products.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.

Capryloyl Glycerin/Sebacic Acid Copolymer
General function
A plant-derived polymer that forms a light film and helps hold a style without a stiff feel.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitFrizz-prone, damaged, or high-friction hairEmollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
DependsCurls or waves needing flexible holdHow rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.

Diheptyl Succinate
General function
A light plant-derived ester used as a silicone alternative for slip and a dry, smooth finish.

Crambe Abyssinica Seed Oil
· Crambe Abyssinica (Abyssinian) Seed Oil
General function
A light oil with very long fatty-acid chains, used as a plant alternative to silicone shine.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitDry, coarse, or high-porosity hairCoats 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 hairA 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 hairNear the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.

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
- 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.
- Seen at $17.99 is the price we have observed for the 2 oz. We need three stores before we call a price commonly seen.
- Good value under $13 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $6.25/oz; at 2 oz that is $13. Under that line you are paying less than most of them.
- About $17 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 2 oz.

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.
Many reviewers say it adds lightweight shine and smooths flyaways, and a little goes a long way.
straight, silk-pressed and natural-hair usersSome reviewers dislike a sticky, greasy or watery feel, and a few say the pump dispenses too much.
lower-rated reviewsHumidity protection is reported to work best on straightened or silk-pressed hair, while curly-haired reviewers see less difference or only partial frizz control.

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.
- 5 sources consulted for this product (2 manufacturer or regulatory, 1 retailer, 2 editorial), last checked 2026-10-11.
- Ingredient references are linked for 4 of 11 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 2026-10-12.
