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.
Heat protection
Stated to 450°F
The brand states a protection temperature. That is a label claim, not a measurement.
Weight on the hair
Rich
Heavy butters and waxes in the first eight ingredients.
Slip and detangling
High
Conditioning agents sit high in the list, so this is a detangling formula.
Needs detergent to remove
Yes
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Water-binding (humectants)
None found
No humectants, so nothing here pulls water into the hair.
Fast-drying alcohol
None
No fast-drying alcohol in the list.
Fragrance
Prominent
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

Full ingredient list (24)
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/Water/Eau
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 ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- solvent
-
2
Cetearyl Alcohol
General function
A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitDry, coarse, or high-porosity hairThe waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.
May suitFrizz-prone, damaged, or high-friction hairDeposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
DependsFine or easily flattened hairNear the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.
- fatty alcohol
- emollient
- thickener

3
Cocos Nucifera (Coconut) Oil
· Cocos Nucifera Oil/Coconut 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.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
International Journal of TrichologyMay suitDry, coarse, or high-porosity hairBecause it penetrates rather than sits on top, it works on hair that loses water through a worn cuticle instead of only slowing evaporation from the surface the way a non-penetrating oil does.
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 suitVery dry or highly damaged hairThe exception to the class read: lauric acid is small and linear enough to enter the shaft rather than only coat it, and in comparison testing coconut oil was the one that reduced protein loss from washing on both undamaged and damaged hair.
- oil
- emollient

Cetyl Esters
General function
A waxy ester blend that replaces spermaceti in creams. It thickens and leaves a smooth, non-greasy finish.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.

A fatty alcohol used to thicken creams and add slip. It softens rather than dries.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

Amodimethicone
General function
A silicone modified to stick where hair is damaged, so it smooths selectively instead of coating everything. It resists rinsing more than plain dimethicone.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
International Journal of TrichologyMay 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.
- silicone
- conditioning agent
- film former

Behentrimonium Methosulfate
General function
A mild cationic conditioner known for heavy detangling with a light rinse-out feel. Common in curly-hair conditioners.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
International Journal of Cosmetic ScienceMay suitDry, coarse, or high-porosity hairA C22 conditioning quat, the chain length that deposits most heavily in electrokinetic testing. It is the slip coarse or porous hair usually needs, delivered by chain length rather than by charge alone.
May suitFrizz-prone, damaged, or high-friction hairA cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
May suitVery dry or highly damaged hairThe class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

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.

Hydrolyzed Wheat Protein
General function
Wheat protein broken into fragments small enough to cling to the hair. It adds temporary strength and body; too much can feel stiff.

A quick-acting conditioning agent that reduces static and combing force. It also helps keep the formula stable.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
International Journal of Cosmetic ScienceMay suitFine or easily flattened hairThe C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.

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
- 5.1 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.
- Commonly seen is the middle half of current prices for the 5.1 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- About $15 is what heat protectants typically cost at this size. Too few of the products that do the same job carry a price for us to draw a good-value line.

A complete formula at an ordinary price: mid-range per ounce among heat protectants, with the working systems in place.
How the score is counted
- 5 products that do the same job cost less per ounce
- Costs more per ounce than 69% of the 891 heat protectants we’ve priced
- Covers 4 of the 6 things a heat protectant should do

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.

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 (3 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
- Ingredient references are linked for 12 of 18 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 2026-08-25.
