Full ingredient list (23)
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.

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.

General function

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.
- Seen at $40 is the price we have observed for the 1 oz. We need three stores before we call a price commonly seen.
- Good value under $5 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $4.87/oz; at 1 oz that is $5. Under that line you are paying less than most of them.
- About $8 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 1 oz.

Formula score
8 of 10
The formula carries what a serum is built around, and 7 products we score as close matches cost at least a quarter less per ounce. The difference is buying the label, not a different formula.
How the score is counted
- 7 products we score as doing the same job cost less per ounce
- Costs more per ounce than 100% of the 79 serums we’ve priced
- Covers 4 of the 6 things a serum should do
- Reviewers mention 3 things they like about how it performs

- No drying alcohol in the first threeFast drying without leading on alcohol.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, 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.

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.

What people report
Recurring themes our researchers wrote in their own words from sourced reviews. We do not 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.
written Laconicum customer reviewEugenia UBdO says it gives dry or wet hair shine and softness with a pleasant scent, but recommends applying only from mid-lengths to ends to avoid a greasy result.

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.
- 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 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 2026-08-27.
