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.
A reset wash that removes oil, buildup, and most residue.
Thick foam that spreads quickly through the hair.
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 strong non-sulfate detergent used in "sulfate-free" shampoos. It cleans about as thoroughly as a sulfate despite the label difference.
Listed in the first three ingredients, it is likely a structural part of this formula.
A strong detergent with no sulfate on the label. It removes deposited films about as completely as a sulfate does.
Sulfate-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.
A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.
Listed in the first three ingredients, it is likely a structural part of this formula.
Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.
The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.
Among 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.
Glycerin, also called glycerol, attracts moisture and mixes completely with water.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
An extract from the leaf of Viola Odorata. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A blue-green algae extract used at low levels for protein and mineral claims.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
An extract from the fruit of Banana (Musa Sapientum). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
An extract from the flower of Banana (Musa Sapientum). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A hold polymer that forms a firm, humidity-resistant film. It is the usual source of a hard cast in gels.
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 light humectant and carrier that helps extracts dissolve.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
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 wax that gives shampoo its pearly look and a slightly richer feel.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A sugar-derived humectant that also helps a formula stay blended.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the 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.
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 cellulose-based conditioning polymer that leaves a thin, static-reducing film. Very common in shampoos as the ingredient that keeps them from stripping.
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 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.

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 mild cleanser that gives a creamy lather and leaves hair less stripped than sulfates.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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 biodegradable hard-water chelator used in place of EDTA.
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 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 · 10 oz
Usually a good value. Most stores sell it under the $12 line, and products that do this job typically go for about $16 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.
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, for washing without sulfates and a protein-free formula
Less suited to anyone sensitive to fragrance, dry or damaged hair, or soft, over-stretchy hair that needs protein
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.
