CONDITIONING AGENT

Panthenol

conditioning agent

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.

At a glance

Four things worth knowing about how this ingredient behaves on hair.

Buildup risk Low

How much of it is left on hair between washes.

Rinse-out behaviour Rinses clean

What it takes to get it off the hair again.

Adhesion Low

Whether hair pulls it in or pushes it away, read from its charge.

Slip Some

How much easier it makes a comb pass.

What it does for a formula

What Panthenol does

The general function first, then how the role changes by product type where we have researched it.

Makes combing easier

Included for feel and detangling rather than for cleaning or structure.

Pulls water inward

Binds water and holds it against the hair rather than adding oil.

Answers to the weather

What a humectant does depends on the air around it as much as on the formula.

Included as a vitamin

Usually present in small amounts, below where label order indicates quantity.

Charge

Nonionic (no charge)

Carries no charge, so it neither clings to hair nor is pushed away by it. Nonionic ingredients are the mild, pH-tolerant workhorses of a formula.

Solubility

Water-solubleOil-solubleWater-dispersibleInsolubleVolatile

Rinses out with water alone, so it does not build up on hair between washes.

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.

May suitFine or easily flattened hair

It hydrates without adding oil or a film, which is the combination fine hair usually needs.

May suitFrizz-prone, damaged, or high-friction hair

Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

May suitVery dry or highly damaged hair

A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

DependsClimate-sensitive or frizz-prone hair

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.

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.

A good sign if you want

easier combing
hydration rather than oil
a named vitamin on the label
a rinse-clean feel

Less relevant if you want to know

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

Seeing it usually means

a secondary conditioning agent, 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)

It does not automatically mean

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.

Commonly paired with

The ingredients that most often appear alongside this one in our library. We leave out the near-universal ones, because they pair with everything and tell you nothing.

The number beside a name is how many products in our library list both.

These ingredients tend to appear together to soften the strand, carry the formula and let it dry, and improve feel after rinsing.

How this page was made

Every number above is counted from the ingredient lists in our own product library: 2355 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.
