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.
Conditioning agents are present, lower in the list.
Oils are present, but low enough to be a finishing touch.
Water-first and light: unlikely to flatten fine hair.
Humectants near the top: binding water is one of its main jobs.
Protein appears, low enough to be a supporting ingredient.
The silicones here are the water-soluble kind.
No chelating agent in the list.
No fragrance is listed.

Full ingredient list (73)
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.
-
1
Water
· Aqua (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
Decolorized Aloe Barbadensis (Aloe Vera) Leaf Juice
· Decolorized Aloe Vera (Aloe Barbadensis) (Leaf) Juice
General function
Aloe leaf juice filtered to remove its yellow latex fraction. Used for light moisture and slip, often in place of some of the water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
- botanical extract
- humectant

3
Sodium Hyaluronate
General function
A large water-binding molecule that sits on the surface holding moisture.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May 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 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.

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

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.

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.
May suitBuild-up-sensitive routinesThe PEG- and PPG-modified silicones disperse in water, so ordinary washing carries them off instead of leaving a film to accumulate.

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 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 $19.99 is the price we have observed for the 1 oz. We need three stores before we call a price commonly seen.
- Good value under $3 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $3.21/oz; at 1 oz that is $3. Under that line you are paying less than most of them.
- About $5 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 1 oz.
Formula
It costs more per ounce than 77% of the 280 scalp treatments we’ve priced, and 2 formulas we score as close matches cost at least a quarter less per ounce.

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.
- 1 source consulted for this product (0 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-10-07.
- Ingredient references are linked for 8 of 19 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 2026-10-08.
