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 strong hold, as stated by the brand.
Synthetic hold polymers — the firmest of the hold systems.
Softening ingredients sit alongside the film formers, so a hard shell is unlikely.
Middle of the range — noticeable on fine hair, light on coarse hair.
The brand claims humidity resistance; the ingredient list cannot confirm it.
No absorbent powders or starches.
Oils sit high in the list — a softening, coating formula.
No fast-drying alcohol in the list.
Nothing here needs a detergent wash to remove.
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 small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.
In styling gel, glycerin helps retain moisture as the product dries, supporting a softer, more flexible finish. The hold itself comes from the formula's film-forming polymers.
Listed in the first three ingredients, it is likely a structural part of this formula.
May suit hair that benefits from added water retention and a softer, more flexible gel finish.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
Consider the climate and the complete formula: prominent humectants can behave differently in very dry air and on frizz-prone hair in high humidity.
A cross-linked acrylate that thickens a gel and dries to a holding film. Cross-linking makes it build viscosity as well as set.
Listed in the first three ingredients, it is likely a structural part of this 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 neutralised acrylate hold polymer used in sprays for firm, humidity-resistant set.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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.
Keeps fragrance and oils dissolved in a watery formula so it stays clear.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A film-forming polymer used for hold and to help other ingredients deposit.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
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 base used in trace amounts to neutralise acidic hold polymers so they thicken and set properly.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.
Argan oil. A medium-weight oil used for shine and softness on the outside of the strand.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
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.
A natural sugar-based humectant that holds water against the strand.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Hydration with no oil attached, so it adds very little weight even high on a list.
Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.
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.
Fragments of the same protein hair is made of. They fill gaps on damaged strands and make hair feel firmer for a few washes.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
Keratin broken all the way down to individual amino acids. Small enough to sit inside the cuticle, used for softness rather than firmness.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
An acid used to set pH and, in scalp products, to loosen flakes.
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.
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.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
It hydrates without adding oil or a film, which is the combination fine hair usually needs.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.
Silk protein broken into amino acids, used for slip and shine rather than strength.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.
A corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.
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 hydrates without contributing weight.
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 large water-binding molecule that sits on the surface holding 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.
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 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.
Grabs metal ions from hard water so they cannot dull the 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.
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.

Formula
A complete read of the format at an ordinary price: mid-range per ounce among gels, with the working systems present.
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.
