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.
Nothing here is built to reduce combing force.
Humectants near the top: binding water is one of its main jobs.
No over-the-counter scalp active.
Nothing here needs a detergent wash to remove.

The ingredients that change a decision

Full ingredient list (13)
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.

Water
· purified water
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
Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Scientific ReportsMay suitDry, coarse, or high-porosity hairHigh-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
May suitVery dry or highly damaged hairBinds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
DependsClimate-sensitive or frizz-prone hairWater moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.

Sorbitol
General function
A sugar-based humectant that adds moisture and a slight cushiony feel.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

DependsClimate-sensitive or frizz-prone hairA humectant moves water in whichever direction the air allows: it holds moisture in humid conditions and can pull it back out of hair in very dry ones.

Stearic Acid
General function
A fatty acid that thickens creams and helps them hold their texture.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

A coconut-derived fatty acid used to build cleansers and stabilise foam.

Theobroma Cacao (Cocoa) Seed Butter
· cocoa butter
General function
A firm plant butter used for sealing and hold in heavier styling creams.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitDry, coarse, or high-porosity hairCoarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.
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 suitVery dry or highly damaged hairA solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.

- emollient
- sealant

Butyrospermum Parkii (Shea) Butter
· shea butter
General function
A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.

Cocos Nucifera (Coconut) 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.
Secondary ingredientLower in the ordered portion of the list, it is more likely playing a supporting role than defining the 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.

How we work this out
- 3.5 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 $9.99 is the price we have observed for the 3.5 oz. We need three stores before we call a price commonly seen.

Less suited to oily scalps and fine hair, hair that tangles the moment it is wet, or very dry or very humid climates

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.
- 3 sources consulted for this product (2 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-10-21.
- Ingredient references are linked for 5 of 7 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 2026-10-22.
