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.

Alcohol Denat.
General function
Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.

A corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.

PubChemDependsFrizz-prone, damaged, or high-friction hairpH 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.

International Journal of TrichologyDependsFrizz-prone, damaged, or high-friction hairThe 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.

May suitCurls or waves needing flexible holdA polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.

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 — grey-market or unverified sellers.
How we work this out
- 3.45 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 $6.60 is the price we have observed for the 3.45 oz. We need three stores before we call a price commonly seen.
- Good value under $19 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $5.56/oz; at 3.45 oz that is $19. Under that line you are paying less than most of them.
- About $43 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 3.45 oz.

Formula score
3 of 10
Low cost per ounce, with a short formula: there is no conditioning agents up front here, and that is a system most scalp treatments carry.
How the score is counted
- Costs less per ounce than 92% of the 159 scalp treatments we’ve priced
- No conditioning agents up front in the formula
- No oils or butters in the working zone either
- Reviewers mention 2 things they like about how it performs
- Conditioning agents up frontWhat makes wet hair comb through.3 pts
- Oils or butters in the working zoneSoftens the strand rather than just coating it.2 pts

- A humectantBinds water into the hair.1 pt
- A pH adjusterBrings the formula to the acidic pH hair prefers.1 pt
- Fragrance kept out of the top eightScent as a finishing touch, not a major share.1 pt
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
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.

Biggest tradeoff

Claims check
What the brand says, against what the formula shows
Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

Reviewers
What people report
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
The scent is very frequently called out as a favorite part of the product, independent of whether the reviewer felt it worked.
general reviewersMany reviewers with oily scalps say it reliably cuts down greasiness and buildup, especially when used alongside the matching shampoo and conditioner.
reviewers with oily scalp/rootsSeveral reviewers with sensitive scalps report burning, tingling or itching during or after the 15-minute wait, sometimes to the point of stopping use.
reviewers describing sensitive scalpA few reviewers say repeated use over weeks left hair drier or more prone to flakes than before, especially on already-dry scalps.
reviewers who used it consistently over several weeksA recurring complaint is that reviewers noticed no real difference in oiliness after using it as directed.

How this page was made
- Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per 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.
- 5 sources consulted for this product (2 manufacturer or regulatory, 0 retailer, 3 editorial), last checked 2026-09-15.
- Ingredient references are linked for 9 of 12 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
- We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
- Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
- Formula readings: derivation v22. Record last updated 2026-09-15.
