What Is Amodimethicone?

Amodimethicone is a modified silicone with amino (nitrogen-containing) functional groups attached to its backbone. These amino groups give it a positive charge that allows it to selectively deposit on damaged areas of the hair, making it smarter than regular dimethicone. It is considered one of the most advanced and hair-friendly silicones available in consumer products.

Source: Silica (sand), chemically synthesized with amino modification

Origin: Synthetic

Also known as: Amino-Functional Silicone, Modified Dimethicone

What Does Amodimethicone Do to Your Hair?

Amodimethicone selectively binds to damaged, negatively charged areas of the hair cuticle rather than coating uniformly like dimethicone. This targeted deposition means it repairs and smooths where it is needed most without building up on healthy sections. It provides exceptional frizz control, heat protection, and color protection while being easier to wash out than dimethicone.

HairAide Verdict

Amodimethicone is the smartest silicone in hair care — it goes where it is needed and skips where it is not. HairAide considers it superior to regular dimethicone for most uses. While not CG-approved, it builds up far less than other silicones. If you use heat tools or color your hair, amodimethicone is an excellent protective ingredient.
