Slows evaporation from the strand more than any other lipid class.
Coats the surface and makes hair feel more pliable.
Sits on the outside of the cuticle and holds moisture in.
Charge

Solubility

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.
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
It stays entirely on the surface, slowing water leaving the fibre — which is real — but in the comparison against coconut oil it did not reduce protein loss from washing — nothing about it enters the strand.
Read where it is listed in the first three ingredients, positions 4–8 or the lower half of the ordered list.It does not disperse in water at all: removing it means a detergent wash, and until then it stays exactly where it landed.
Read where it is listed in the first three ingredients, positions 4–8 or the lower half of the ordered list.Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.

Why it matters to shoppers
What seeing this ingredient tells you, what it does not, and the limits of our own method.
- softness and shine
- a softer feel
- a barrier that slows water loss
- something that lasts through the day
- an exact safety score (we do not publish one for any ingredient)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 supporting emollient alongside the main ingredients in our styling pastes
- it was on the printed ingredient list of every product we counted (we read labels, not marketing copy)
- 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We do not publish safety scores or hazard grades.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.

How this page was made
- Every number above is counted from the ingredient lists in our own product library: 70 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.
