What the formula actually does
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.
Conditioning agents sit high in the list — this is a detangling formula.
Butters near the top: a heavy, softening formula.
Middle of the range — noticeable on fine hair, light on coarse hair.
Humectants near the top — water-binding is a headline mechanism here.
Protein appears, low enough to be a supporting ingredient.
Nothing here needs a detergent wash to remove.
Chelators are present — they bind hard-water and pool minerals.
No fragrance is listed.
Ingredients that matter
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.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| WaterAqua/Water/Eau | solvent | The base everything else is dissolved in | Neutral |
| Cetearyl Alcohol | fatty alcohol | Thickens and conditions — not a drying alcohol | Softens |
| Behenamidopropyl Dimethylamine | conditioning agent | Conditions and softens — this is what makes it comb through | Detangles |
| Propanediol | humectant | Pulls water into the hair | Moisturizes |
| Glycerin | humectant | Pulls water into the hair | Moisturizes |
| Butyrospermum Parkii (Shea) Butter | butter | Heavy softening — this is what makes it rich | Heavy |
| Lactic Acid | pH adjuster | Fine-tunes the pH | Moisturizes |
| Pentylene Glycol | humectant | Adds a little water-binding | Moisturizes |
| Keratin | protein | A small amount of protein | Protein |
| Melaleuca Alternifolia (Tea Tree) Leaf Oil | botanical extract | A trace plant extract | Fragrance |
| Mentha Piperita (Peppermint) Oil | botanical extract | A trace plant extract | Fragrance |
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.
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Listed in the first three ingredients, it is likely a structural part of this formula.
A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.
Listed in the first three ingredients, it is likely a structural part of this formula.
The 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.
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.
A light conditioning agent favoured in silicone-free formulas for slip and detangling.
Listed in the first three ingredients, it is likely a structural part of this formula.
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.
The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.
Substantive by design. A routine with no detergent wash gives it nothing to leave with.
A corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Light and water-binding rather than oily, so it hydrates without contributing weight.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
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.
A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
Water 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.
A rich, solid plant butter used for heavy conditioning on coarse or dry hair. High in the list it makes a product decidedly heavy.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Coarse, porous hair loses water quickly and can carry the weight; a butter slows that loss more than a thin oil does.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A solid fat melts onto the strand at body temperature and stays there, which is the heaviest surface moisture-holding a formula can offer.
An acid used to set pH and, in scalp products, to loosen flakes.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
A 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.
A humectant that also helps preserve the formula, often used where a brand wants a short preservative list.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Light and water-binding rather than oily, so it hydrates without contributing weight.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
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.
The fully hydrogenated form of squalene, now made from olive or sugarcane rather than shark liver. Hydrogenation is what makes it so slow to oxidise; it spreads very lightly and absorbs without a greasy film.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
The protein hair is made of. On the outside of the strand it fills gaps and firms up the feel for a few washes.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Unhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.
Tea tree essential oil, used in scalp products for its sharp scent and traditional clarifying reputation.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
Peppermint essential oil, used for scent and the cooling feeling on the scalp.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

A light humectant and carrier that helps extracts dissolve.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Light and water-binding rather than oily, so it hydrates without contributing weight.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
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.
A coconut-derived preservative booster that also binds trace metals.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.
Copper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.
A fast-evaporating carrier that lets oils and polymers spread thinly, then leaves nothing behind.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Formula
A complete read of the format at an ordinary price: mid-range per ounce among scalp treatments, with the working systems present.
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.
Does the same job, for less
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Claims check
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.
