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.
Slip and detangling
Some
Some slip, mostly from esters or silicones rather than conditioners.
Oils and butters
Present, high in the list
Oils sit high in the list: a softening, coating formula.
Weight on the hair
Rich
Heavy butters and waxes in the first eight ingredients.
Water-binding (humectants)
Low
Humectants appear, but low enough to be a minor part.
Protein
None
No protein or amino acids in the list.
Needs detergent to remove
No
Nothing here needs a detergent wash to remove.
Hard-water defence
None
No chelating agent in the list.
Fragrance
Prominent
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

What the list leaves out, and what it carriesThe list carries no sulfates, silicones, or drying alcohols. No protein: a moisture formula, not a repair one. Fragrance is on the label. Heavier butters sit in the working part of the list.

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
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.
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.

Propylene Glycol

PubChemMay suitFine or easily flattened hairLight and water-binding rather than oily, so it adds less weight than oils or butters do.
May suitVery dry or highly damaged hairA small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
DependsClimate-sensitive or frizz-prone hairA 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.

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
- 4 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 $5.78 is the price we have observed for the 4 oz. We need three stores before we call a price commonly seen.
- Good value under $10 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $2.46/oz; at 4 oz that is $10. Under that line you are paying less than most of them.
- About $10 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 4 oz.

Low cost per ounce, with a short formula: there is no conditioning agents up front here, and that is a system most scalp treatments carry.
How the score is counted

- No conditioning agents up front in the formula
- No slip for detangling either

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.

Final decision
Should you buy it?
A solid pick for the hair it suitsBest user
Hair that stiffens on protein who want a protein-free formula and a formula with real substance
Biggest tradeoff
Not ideal for anyone sensitive to fragrance or oily scalps and fine hair
Best alternative if not
Nothing in our library matches it closely at a lower price.
We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.
Claims check
What the brand says, and what the formula shows
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.

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 (1 manufacturer or regulatory, 1 retailer, 1 editorial), last checked 2026-09-08.
- Ingredient references are linked for 7 of 16 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 2026-09-08.
