SILICONE
Amodimethicone
- silicone
A silicone modified to stick where hair is damaged, so it smooths selectively instead of coating everything. It resists rinsing more than plain dimethicone.

What it does for a formula
What Amodimethicone does
The general function first, then how the role changes by product type where we have researched it.
Fills the gaps between lifted cuticle scales so light reflects evenly.
Lowers the drag a comb feels, which is most of what "detangling" means.
Included for feel and detangling rather than for cleaning or structure.
The film is what holds a shape once the water has gone.
Charge
Positively charged, so it is drawn to the negatively charged, damaged areas of hair and stays behind after rinsing. That is why conditioning happens where the wear is.
Solubility
Spreads through water without truly dissolving, and normal shampooing removes it.

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 surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.
Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
Damage strips the 18-MEA layer off the cuticle and leaves the surface underneath more negatively charged. An amine-functional silicone picks up a positive charge in an acidic conditioner and binds hardest exactly there, rather than coating evenly.
Read where it is listed in the first three ingredients, positions 4–8 or the lower half of the ordered list.Better than the class read suggests, but not exempt: the deposited films carry like charges and repel each other, so it layers on itself far less readily than an uncharged silicone. It is still a silicone film that ordinary washing may not fully remove.
Read where it is listed in the first three ingredients, positions 4–8 or the lower half of the ordered list.How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.
Near the top of a list, a conditioning film adds weight that fine hair loses volume to.

Why it matters to shoppers
What seeing this ingredient tells you, what it does not, and the limits of our own method.
- slip and surface smoothing
- easier combing
- a style that holds
- a product ordinary shampooing removes
- 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 silicone, listed below the main ingredients in our conditioners
- it was on the printed ingredient list of every product we counted (we read labels, not marketing copy)
- it is meant to stay on the hair rather than rinse away
- buildup, since the water-soluble ones rinse out with ordinary shampoo
- 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.
Why some people avoid it
A conditioning agent that lays a smooth film on the cuticle, which is what delivers slip, shine and frizz control.
The water-insoluble ones need a detergent wash to remove, so on a routine that avoids detergent they accumulate and can leave hair feeling coated. That is the curly-method objection, and it is about buildup rather than harm. Water-soluble silicones rinse out and do not raise it.
Where regulators stand: Permitted. Some cyclic silicones are restricted in the EU on environmental grounds (they persist in waterways), not for anything to do with skin.
A formulation preference, not a regulatory finding

How this page was made
- Every number above is counted from the ingredient lists in our own product library: 850 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.
