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.
No oils or butters in the list.
Middle of the range: noticeable on fine hair, light on coarse hair.
No protein or amino acids in the list.
No humectants, so nothing here pulls water into the hair.
Conditioning agents sit high in the list, so this is a detangling formula.
Nothing here needs a detergent wash to remove.
No fragrance is listed.
Ingredients that matter
The workhorse ingredients, plus anything lower down that changes a decision. The 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 |
|---|---|---|---|
| Diethylhexyl Maleate | emollient | Softens and smooths the strand | Softens |
| Oleyl Alcohol | fatty alcohol | Thickens and conditions (not a drying alcohol) | Softens |
| Alcohol Denat. | drying alcohol | Speeds drying but can leave hair feeling dry | Drying |
| Stearamidopropyl Dimethylamine | conditioning agent | Conditions and softens so hair combs through | Detangles |
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.
A lightweight synthetic ester used as an emollient in styling creams and finishing products to soften texture and add slip without heaviness.
Listed in the first three ingredients, it is likely a structural part of this formula.
A liquid fatty alcohol that adds slip and helps other oils spread.
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.
Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.
Listed in the first three ingredients, it is likely a structural part of this formula.
Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
Porous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.
It evaporates quickly and takes some water with it. On hair already short of moisture, a formula built on a lot of it can finish drier than it started.
A gentle conditioning agent activated by the acid in the formula. It smooths the cuticle without much build-up.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

Price · 10.14 oz
Priced above the products that do the same job. Stores sell it above the $24 line; products that do this job typically go for about $38 at this size.
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.
Formula
Mid-range per ounce for a shorter formula: there is no rich emollients here.
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.

Final decision
People sensitive to fragrance who want a formula with no added fragrance and a product with no scent
Less suited to very dry or high-damage hair, soft, over-stretchy hair that needs protein, or very dry hair that needs water-binding

Claims check
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.
