The workhorse ingredients, plus anything lower down that changes a decision. The chips name what an ingredient does. They are not safety scores, and no ingredient here is rated good or bad on its own.

Full ingredient list (23)
In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.

1
Cyclopentasiloxane
General function
A light, fast-evaporating silicone that spreads other ingredients then leaves. It gives serums their weightless glide.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitBuild-up-sensitive routinesIt leaves the hair by evaporating rather than by being washed off, so it is not part of what accumulates.
May suitClimate-sensitive or frizz-prone hairA surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
May suitFine or easily flattened hairA cyclic silicone evaporates after it has spread the formula, so it carries the other ingredients without leaving weight behind.
- silicone
- emollient
-
2
Diphenyl Dimethicone
General function
A silicone. Silicones coat the strand for slip, shine and frizz control; unless the name carries PEG or PPG, removing one takes a detergent rather than water.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
May suitClimate-sensitive or frizz-prone hairA surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
May suitFrizz-prone, damaged, or high-friction hairLays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.
May not suitBuild-up-sensitive routinesDimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.
- silicone
- conditioning agent

3
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.
Leading ingredientListed in the first three ingredients, it is likely a structural part of this formula.
PubChemMay suitFine or easily flattened hairEvaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
May not suitDry, coarse, or high-porosity hairPorous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.
May not suitVery dry or highly damaged hairIt evaporates quickly and takes some water with it. On hair already short of moisture, a formula built on a lot of it can finish drier than it started.

- solvent

Fragrance
· Parfum (Fragrance)
General function
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.

May suitFine or easily flattened hairA light emollient: it softens the surface with noticeably less weight than an oil or a butter.
May suitFrizz-prone, damaged, or high-friction hairSpreads thin and lowers friction between strands without the heaviness of a fixed oil.

Panthenol
General function
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.
Estimated lower-concentration zoneIt appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
PubChemMay suitFine or easily flattened hairIt hydrates without adding oil or a film, which is the combination fine hair usually needs.
May suitFrizz-prone, damaged, or high-friction hairDeposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
May suitVery dry or highly damaged hairA humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

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.
How we work this out
- 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.
- Commonly seen is the middle half of current prices for the 1 oz at recognised stores. We leave out the cheapest and most expensive quarters, so one sale or one overpriced listing can’t move it.
- Good value under $4 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $3.62/oz; at 1 oz that is $4. Under that line you are paying less than most of them.
- About $5 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 1 oz.

The formula carries what a serum is built around, and 8 products we score as close matches cost at least a quarter less per ounce. The difference is the label, not the formula.
How the score is counted
- 8 products we score as doing the same job cost less per ounce
- Costs more per ounce than 99% of the 136 serums we’ve priced

The formula score measures completeness for the job: a weighted share of the systems this product type is usually built around that we find in this list. It does not rate how well the product works or its quality, and it never compares across product types.
Does the same job, for less
Formulas that do the same things (cleanse, condition, coat or hold) for less per ounce. Scent, texture and where you buy them can still differ.

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.

Themes that come up again and again in sourced reviews, written by our researchers in their own words. We don’t store or scrape star ratings.
Alicia G.R.G.R. says the serum seals their hair, smells great, gives a salon-like result, and works for them on dry hair.
written Laconicum customer reviewmaria pr reports that the serum leaves strong curly hair silky with fantastic shine, also works on straight hair, and seals the ends without feeling like an ordinary product.
written Laconicum customer reviewEva C. finds it effective at sealing the mid-lengths and ends and reducing frizz immediately after washing.

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.
- 3 sources consulted for this product (1 manufacturer or regulatory, 2 retailer, 0 editorial), last checked 2026-08-27.
- Ingredient references are linked for 12 of 23 product-aware annotations on this page. Fit notes are general formulation guidance. They aren’t a verdict on the finished product or on you.
- We haven’t tested this product in a lab, and we don’t physically test your hair. Formula readings come from the ingredient list. Claims about how it behaves are labelled as the brand's.
- Ingredient order tells you relative amount only above roughly 1%. Prices are what we saw on the dates shown and can change.
- 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 v23. Record last updated 2026-08-27.
