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.
Weight on the hair
Light
Water-first and light: unlikely to flatten fine hair.
Slip and detangling
High
Conditioning agents sit high in the list — this is a detangling formula.
Water-binding (humectants)
High
Humectants near the top — water-binding is a headline mechanism here.
Oils and butters
None
No oils or butters in the list.
Protein
None
No protein or amino acids in the list.
Heat protection
Stated to 450°F
The brand states a protection temperature — a label claim, not a measurement.
Needs detergent to remove
No
Nothing here needs a detergent wash to remove.

Full ingredient list (27)
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.

Water
· Water/Eau/Aqua

Peg/Ppg-8/3 Laurate

Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay 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.

Polyquaternium-37
General function
A thickening polymer that gives creams and curl products their bounce and helps them cling to the strand.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitCurls or waves needing flexible holdCationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
May suitFrizz-prone, damaged, or high-friction hairA cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

Propylene Glycol Dicaprylate/Dicaprate
General function
A light, dry-feeling ester that spreads other ingredients and softens without a greasy finish.

May suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.

Glycerin
General function
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.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.

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
- 1.7 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 $17.10 is the price we have observed for the 1.7 oz. We need three stores before we call a price commonly seen.
- Good value under $2 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $0.92/oz; at 1.7 oz that is $2. Under that line you are paying less than most of them.
- Each size is guarded on its own, so a multipack or a marketplace listing at one size cannot move another.
- About $2 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 1.7 oz.

Formula score
10 of 10
The formula carries what a leave-in is built around, and 8 products we score as close matches cost at least a quarter less per ounce. The difference is buying the label, not a different formula.
How the score is counted
- 8 products we score as doing the same job cost less per ounce
- Costs more per ounce than 91% of the 549 leave-ins we’ve priced
- Covers 6 of the 6 things a leave-in should do

- No detergent-dependent filmNothing that needs a clarifying wash to remove.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
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
What the brand says, against what the formula shows
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.

What people report
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
Pleasant, salon-like scent that makes hair feel and smell smoother
Lightweight, no greasy residue or heavy feel; but some report it left hair frizzy, dry, or too perfume-y compared to Living Proof Restore
Detangles thick hair without leaving it flat, though light on oils for very tangled hair

How this page was made
- Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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 (3 manufacturer or regulatory, 0 retailer, 0 editorial), last checked 2026-08-25.
- Ingredient references are linked for 11 of 17 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
- We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
- 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 v22. Record last updated 2026-08-25.
