At a glance
Four things worth knowing about how this ingredient behaves on hair.
How much of it is left on hair between washes.
What it takes to get it off the hair again.
How much oil the solid takes up.
A solid at room temperature holds hair where it is put.

What it does for a formula
What Mica does
The general function first, then how the role changes by product type where we have researched it.
A solid particle: it changes how a formula looks and feels, not what it cleans.
Purely how the product looks in the bottle.
The colour of what is in the bottle or, in a depositing product, of your hair.
It dissolves in neither water nor oil, so it is removed by washing or brushing.
Charge
Charge is not recorded for this ingredient.
Solubility
Does not dissolve in water or oil. It sits on the surface and is removed mechanically or by cleansing.

We have not researched differences by product type yet. The reading below comes from where it sits on the labels in our library.
Position footprint
Every listing in our library, by position on the label.
| Positions | Zone | Listings |
|---|---|---|
| 1-3 | Leading | 1 |
| 4-8 | Supporting | 14 |
| 9-15 | Secondary | 27 |
| 16-25 | Lower | 38 |
| 26+ | Trace | 23 |
How to read this
US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order.
So position tells you about relative amount only above that line, and we never convert a position into a percentage.
Who should pay attention
Formulation guidance for specific hair conditions, limited to the label positions where it applies. It is not a conclusion about any finished product, or about you.
A violet or blue colorant sits opposite yellow on the colour wheel, so a trace of it deposited on the surface makes a warm cast read cooler. It washes out over the following few washes.
A deposited colorant is a surface layer. It is a very small amount of material, but on a routine already fighting for root lift it is one more thing sitting on the strand.
Read where it is listed in the first three ingredients or positions 4–8.Read from this ingredient’s chemical class. Where we have researched the ingredient itself, that reading replaces the class one.
Why it matters to shoppers
What seeing this ingredient tells you, what it does not, and the limits of our own method.
- body and opacity
- a creamy-looking product
- a product whose colour you can see
- a visible surface effect
- an exact safety score (we do not publish one for any ingredient)
- how a finished product performs, which depends on the whole formula, not one line of it
- the exact percentage in a bottle, because label position never converts into a number
- a secondary mineral, listed below the main ingredients in our shampoos
- it was on the printed ingredient list of every product we counted (we read labels, not marketing copy)
- a treatment effect (it changes how the formula looks and feels)
- that it will change your hair colour
- that a product is right or wrong for you
We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.

The number beside a name is how many products in our library list both.
These ingredients tend to appear together to absorb oil and add texture, carry the formula and let it dry, and keep the formula stable.

How this page was made
- Every number above is counted from the ingredient lists in our own product library: 103 of 6816 researched products list this ingredient. Nothing on this page is written per ingredient.
- The dots are levels, not scores. Each one comes from what kind of ingredient it is (its chemical class, charge and solubility) or from where it sits on the labels we have.
- US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Position tells you about relative amount only above that line, and we never convert a position into a percentage.
- The prominence bands (leading, supporting, secondary) are the same ones the product pages use to read a single label, applied here to the median position across a category.
- We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.
- Identifiers and references appear only when a published source is attached to this entry. Without one, we leave the row out rather than fill it in.
- This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
