Scalp treatment
Scent:
The ingredient list declares fragrance. What it smells of is not stated, and we do not guess.

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.
Conditioning agents are present, lower in the list.
No oils or butters in the list.
Water-first and light: unlikely to flatten fine hair.
Humectants near the top — water-binding is a headline mechanism here.
Protein appears, low enough to be a supporting ingredient.
Nothing here needs a detergent wash to remove.
Chelators are present — they bind hard-water and pool minerals.
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.
| Ingredient | What it does | Why it matters | Chip |
|---|---|---|---|
| Water | solvent | The base everything else is dissolved in | Neutral |
| Glycerin | humectant | Pulls water into the hair | Moisturizes |
| Polysorbate 20 | solubilizer | Keeps oils dissolved in water | Stabilizes |
| Rosmarinus Officinalis (Rosemary) Leaf Extract | botanical extract | A trace plant extract | Stabilizes |
| Caffeine | active | A secondary active | Active |
| Pisum Sativum (Pea) Peptide | protein | A small amount of protein | Protein |
| Aloe Barbadensis Leaf Juice | humectant | Adds a little water-binding | Moisturizes |
| Zingiber Officinale (Ginger) Root Extract | botanical extract | A trace plant extract | Neutral |
| Fragrance | fragrance | The scent | Fragrance |
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.
Listed in the first three ingredients, it is likely a structural part of this 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.
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.
Keeps fragrance and oils dissolved in a watery formula so it stays clear.
Listed in the first three ingredients, it is likely a structural part of this formula.
Rosemary extract, used both as a scent note and as a natural antioxidant in scalp products.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Included in scalp and thickening products for label appeal. Evidence for applied caffeine changing hair growth is limited.
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 short-chain pea protein used for strength and body claims in vegan formulas.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Unhydrolysed protein is too large to enter the strand. It sits on the surface, which is a coating effect rather than internal reinforcement.
Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.
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.
Ginger extract, a traditional scalp botanical used at low levels.
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 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 small humectant and solvent that keeps formulas stable and helps active ingredients spread.
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 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 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.
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.
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.
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.

Price · 2 oz
Priced above the products that do the same job. Stores sell it above the $8 line; products that do this job typically go for about $31 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
Both the formula and the price land mid-range: it covers the core of what a scalp treatment does and costs about what scalp treatments cost per ounce.
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.

Final decision
Fine or easily-flattened hair who want something that will not weigh hair down and a silicone-free formula

Claims check
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
Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings.
Reviewers consistently describe the serum as lightweight and non-greasy even when applied to the scalp daily, with several noting it leaves no residue on clean hair.
general reviewers on the brand's own review widgetMultiple reviewers with a dry, flaky or itchy scalp report visible relief and calmer skin after regular use, especially in cold-weather months.
reviewers who described a dry or itchy scalpReviewers coping with thinning hair or recent hair loss report a fuller, thicker-looking result, most often when the serum is used alongside the brand's thickening shampoo and conditioner rather than alone.
