General function
Vitamin B3, used in scalp products for conditioning claims.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.

Polyquaternium-37
General function
A thickening polymer that gives creams and curl products their bounce and helps them cling to the strand.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitCurls or waves needing flexible holdCationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.
May suitFrizz-prone, damaged, or high-friction hairA cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.
May suitMaximum-hold stylingFilm formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

Propylene Glycol Dicaprylate/Dicaprate
General function
A light, dry-feeling ester that spreads other ingredients and softens without a greasy finish.
Supporting ingredientListed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
May suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.

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 TrichologyMay suitBuild-up-sensitive routinesHolds hard-water minerals in solution so they rinse away instead of depositing on the hair.
May suitFrizz-prone, damaged, or high-friction hairThe 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.
May suitGray, silver, or brass-prone hairWhere a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

How we work this out
- 5.1 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 $39.43 is the price we have observed for the 5.1 oz. We need three stores before we call a price commonly seen.
- Good value under $13 comes from the 6 products we score as doing the same job as this one. A quarter of them cost less than $2.50/oz; at 5.1 oz that is $13. Under that line you are paying less than most of them.
- About $18 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 5.1 oz.

Final decision
Should you buy it?
Above-range price, specific fitBest user
People who want maximum slip, looking for real detangling slip and a silicone-free formula
Biggest tradeoff
Not ideal for anyone sensitive to fragrance, very dry or high-damage hair, or vegan and cruelty-free shopping
Best alternative if not
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
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.

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, 3 retailer, 1 editorial), last checked 2026-10-03.
- Ingredient references are linked for 17 of 26 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
