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, buildup, and most residue — a reset wash.
Thick foam that spreads quickly through the hair.
Some slip, mostly from esters or silicones rather than conditioners.
No humectants found — nothing here pulls water into the hair.
No over-the-counter scalp active.
Chelators are present — they bind hard-water and pool minerals.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
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. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.
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 high-foaming, strongly cleansing detergent. It clears build-up thoroughly and is the harsher of the two common sulfates.
Listed in the first three ingredients, it is likely a structural part of this formula.
A sulfate detergent removes deposited silicone, wax and styling films in one wash, which is what resets a routine before build-up is visible.
Fine hair that goes limp under conditioning films usually reads a full detergent wash as volume returning.
Coarse and high-porosity hair loses water quickly on its own; an efficient detergent removes the surface oils that were slowing that down.
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 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.
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.
A coconut-derived thickener that stabilises shampoo foam and gives the liquid its body.
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.
A sugar-derived non-ionic detergent, among the gentlest in use. It cleanses with little foam of its own and little sebum removal.
Gentle cleansing leaves water-insoluble deposits largely in place; they come off with a stronger wash, not this one.
Table salt. In shampoo it is used to thicken the liquid, not to treat the hair.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
White ginger lily extract, used at low levels for scent association and label appeal.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
An amino silicone used in heat-protection and smoothing products for a durable film.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.
A water-soluble silicone that smooths without the build-up concern of standard silicones.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
The PEG- and PPG-modified silicones disperse in water, so ordinary washing carries them off instead of leaving a film to accumulate.
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Delivers the slip and surface smoothing of a silicone without needing a detergent wash to remove it afterwards.
A wax that makes shampoo look pearly and adds 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 fine mineral powder that absorbs oil and adds grip. It is what makes texture powders and matte pastes feel dry to the touch.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
A dry powder takes up oil and adds friction between strands, which is most of what root lift in fine hair actually is.
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.
Binds the metal ions in hard water so they cannot dull hair or destabilise the formula.
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 strong base used in trace amounts to raise pH; fully neutralised in the finished product.
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 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. Alkaline conditions raise the fibre's surface charge and lift the scales — but the finished pH is not on the label.
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 fragrance component with a faint balsamic scent, named separately on the label because it is 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 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.

Sold through salons at a price 7 products that do the same job undercut — the distribution is part of what you are paying for.
The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job, for less
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.
