Ingredients that matter
The ingredients that change a decision
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.

What the list leaves out, and what it carriesThe list carries no sulfates, silicones, or drying alcohols. Protein sits high: this is a strengthening step rather than a moisture one. Fragrance is on the label.
Full ingredient list (19)
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.

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.

Sodium C14-16 Olefin Sulfonate
General function
A strong non-sulfate detergent used in "sulfate-free" shampoos. It cleans about as thoroughly as a sulfate despite the label difference.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitBuild-up-sensitive routinesA strong detergent with no sulfate on the label. It removes deposited films about as completely as a sulfate does.
May not suitVery dry or highly damaged hairSulfate-free on the label is a naming fact, not a mildness one: this is an efficient detergent, and hair short of moisture can feel it.

Cocamidopropyl Betaine
General function
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
Indian Journal of DermatologyMay suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.
May not suitBuild-up-sensitive routinesThe mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
DependsVery dry or highly damaged hairAmong the mildest detergents in use — it is what baby shampoos are built on — but it is almost always the second detergent in a formula. How much a wash strips is still decided by the primary detergent listed above it.

Decyl Glucoside
General function
A sugar-derived, low-foam cleanser used in gentle and curly-method shampoos.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
PubChemMay suitDry, coarse, or high-porosity hairMild cleansing leaves more surface lubrication in place on hair that dries out quickly.

A short-chain pea protein used for strength and body claims in vegan formulas.
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.
DependsVery dry or highly damaged hairUnhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.

Hydrolyzed Rice Protein
General function
A light plant protein that adds body and shine, popular in volume products.
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 suitFrizz-prone, damaged, or high-friction hairFilling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

Starch Hydroxypropyltrimonium Chloride
General function
A positively charged conditioning agent. Damaged hair carries a negative charge, so it deposits where the damage is and makes wet hair comb through.
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 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.

Panthenol
General function
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.
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.

Citric Acid
General function
Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

International Journal of TrichologyDependsFrizz-prone, damaged, or high-friction hairThe alkali half of a pH-adjusting pair, used in small amounts to bring a formula up to its target rather than to make it alkaline.

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
- 13.02 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 $28.99 is the price we have observed for the 13.02 oz. We need three stores before we call a price commonly seen.
- Good value under $12 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.92/oz; at 13.02 oz that is $12. Under that line you are paying less than most of them.
- About $21 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 13.02 oz.

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.

Reviewers
What people report
Themes that come up again and again in sourced reviews, written by our researchers in their own words. We don’t store or scrape star ratings.
Many reviewers report softer, shinier hair after washing, and some say it looked fuller.
Reviewers across hair typesSeveral reviewers say the shampoo left their hair dry and straw-like, even after conditioning.
Reviewers across hair typesSeveral reviewers say the amount they received was too little to wash their hair fully.
Reviewers with long or very short hairReviewers split on scent: many like its fresh, clean fragrance, while others find it strong and cologne-like.
Reviewers across hair typesSeveral reviewers say they cannot yet judge the growth claims, having used it only briefly.

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.
- 4 sources consulted for this product (0 manufacturer or regulatory, 4 retailer, 0 editorial), last checked 2026-10-31.
- Ingredient references are linked for 10 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 2026-08-25.
