What the formula actually does
Read from the label, not the marketing
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.
Water-first and light: unlikely to flatten fine hair.
Conditioning agents are present, lower in the list.
Water-insoluble silicones or waxes: a detergent wash is what removes them.
Humectants near the top: binding water is one of its main jobs.
Contains fast-drying alcohol, which speeds drying but can leave hair feeling dry.
Fragrance is in the first eight ingredients, so it makes up a larger share of the formula.

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.

Glycerin
General function
Glycerin, also called glycerol, attracts moisture and mixes completely with water.

DependsClimate-sensitive or frizz-prone hairWater 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.

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
- 8.5 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 $19 is the price we have observed for the 8.5 oz. We need three stores before we call a price commonly seen.
- Good value under $19 comes from the 7 products we score as doing the same job as this one. A quarter of them cost less than $2.24/oz; at 8.5 oz that is $19. Under that line you are paying less than most of them.
- About $19 is what those same products typically cost at this size: the midpoint of their prices per ounce, scaled to 8.5 oz.
Formula
The formula covers the core of what a heat protectant does, and it costs less per ounce than most heat protectants in our library.
How the score is counted

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.

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.
- 1 source consulted for this product (0 manufacturer or regulatory, 0 retailer, 1 editorial), last checked 2026-11-01.
- Ingredient references are linked for 16 of 18 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 2026-11-01.
