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.
Removes oil and product; leaves some conditioning behind.
An ordinary shampoo lather.
Conditioning agents are present, lower in the list.
Humectants near the top: binding water is one of its main jobs.
No over-the-counter scalp active.
Contains chelators, which bind hard-water and pool minerals.
Nothing here needs a detergent wash to remove.
No protein or amino acids in the list.
Fragrance is listed; it sits below the working ingredients.
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.

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.
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Listed in the first three ingredients, it is likely a structural part of this formula.
A gentle, dense-lathering cleanser used as the primary detergent in many sulfate-free shampoos.
Listed in the first three ingredients, it is likely a structural part of this formula.
The detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.
A gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.
Cleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Listed in the first three ingredients, it is likely a structural part of this formula.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
Water 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.
A mild cleanser that keeps foaming in hard water and rinses cleanly.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
The detergent class most curl routines are built around: it lathers and cleanses without stripping the strand back to bare.
A gentler detergent leaves more of the surface oil that slows water loss from coarse or porous hair.
Cleanses with less sebum removal than a sulfate detergent, so hair that is short of moisture keeps more of it through the wash.
A sugar-derived thickener used to build body in sulfate-free cleansers.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A mild co-cleanser that keeps foam stable in hard water.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
One of the mildest detergent classes. It is usually there to let a formula lather without a harsher detergent doing the work.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
A mild cleanser that accompanies sodium lauroyl methyl isethionate in gentle shampoo bases.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Cleansing is what lifts deposited films off the strand. How completely depends on which detergent it is and how high on the list it sits.
Every detergent removes some sebum along with the product it is there to wash out. Which detergent it is matters more than that there is one.
Flaxseed oil, used for softness; the seed extract is used instead for natural hold.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.
A cross-linked acrylate that thickens a gel and dries to a holding film. Cross-linking makes it build viscosity as well as set.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
A readily biodegradable chelator used in place of EDTA to bind hard-water minerals.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.
Copper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.
A wax that gives shampoo its pearly look and a slightly richer feel.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A conditioning polymer that improves wet combing and adds body. Repeated use can build up on fine hair.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Cationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
A cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
A conditioning polymer made from guar bean gum. It deposits during rinsing, which is why sulfate shampoos can still leave hair soft.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.
Cationic conditioners bind to the negatively charged damaged cuticle, laying it flat and cutting the friction that causes combing breakage.
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.
A sugar-derived humectant that also helps a formula stay blended.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
A 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.
A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
A gentle preservative helper that also holds a little moisture.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Humectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.
A 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.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.
The acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.
A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A solvent that keeps other ingredients dissolved and helps preservatives work.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Light and water-binding rather than oily, so it adds less weight than oils or butters do.
A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.
A 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.
A cellulose thickener used for slip and light hold in gels and creams.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.
A soft film binds neighbouring strands together, which is most of what helps flyaways lie down.
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.
A sugar alcohol that binds water and gives a light, non-sticky moisturised feel.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
A 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.
An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
A lemon-scented fragrance component listed separately as a recognised allergen.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A rose-like fragrance component named separately as a recognised allergen.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A citrus-smelling fragrance component that EU rules require to be named separately because some people react to it.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A floral fragrance component listed separately as a recognised contact allergen.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A certified colour that tints the product itself. It does not colour hair.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A violet or blue colorant sits opposite yellow on the colour wheel, so a trace of it deposited on the surface makes a warm cast read cooler. It washes out over the following few washes.

Price · 11 oz
Usually a good value. Most stores sell it under the $10 line, and products that do this job typically go for about $14 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. and 1 listing we don’t count, from grey-market or unverified sellers.
Formula
A complete formula at an ordinary price: mid-range per ounce among shampoos, with the working systems in place.
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
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
Colour-treated hair, looking for washing without sulfates and a protein-free formula
Not ideal for anyone sensitive to fragrance, soft, over-stretchy hair that needs protein, or very dry or very humid climates
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
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.
Non-stripping cleanse that removes buildup while helping coils stay hydrated
A moderate detergent system: enough for light residue, not a monthly reset.
Light residue, not heavy build-up.
Sulfate-free, paraben-free, vegan, cruelty-free
No sulfate detergents appear in the ingredient list.
