Amodimethicone (Amino Silicone)
INCI · Amodimethicone
Amodimethicone (INCI: Amodimethicone), described as one of hair care's highest-performing conditioning silicones, is a dimethicone derivative functionalised with an amino, nitrogen-containing group. This distinguishes it from conventional dimethicone: the amino group gives a slight positive tendency, allowing selective adhesion to hair areas negatively charged by washing, heat or colour damage. It therefore targets areas most in need of smoothness. Through this substantivity, amodimethicone smooths the cuticle to give slip, shine and reduced visible frizz; its conditioning feel is associated with greater persistence through washing than conventional dimethicone. The common perception that silicone suffocates hair or builds up needs context. Amodimethicone is generally used at low doses as an emulsion, and its anti-adhesion tendency means it does not produce noticeable build-up in most uses. Even so, layering a very heavy silicone routine on fine hair can feel weighty; this concerns the routine and cleansing system more than the ingredient alone. Labels show 'Amodimethicone'. We discuss silicones' formulation roles in a separate Academy article; Klaris considers amodimethicone alongside silicone type, dose and cleansing context.
i. Cosmetic Functions
Frequently Discussed Effects
The following headings summarise areas of effect frequently discussed in the literature; visible results in each area require regular use and a suitable formula.
Smoothness That Adheres to Hair
Its amino group selectively adheres to damaged, negatively charged areas, smoothing the strand surface.
Shine and Frizz Appearance
Smoothing the cuticle supports shine and reduced visible frizz.
A Lasting Feel
Associated with a conditioning feel that lasts through washing longer than conventional dimethicone.
Mechanism
What Happens Within the Skin?
The following points summarise mechanisms from dermocosmetic literature in plain English. Klaris presents them as background information to help readers understand the context, not as medical claims.
Step 1
Amino-Functional Silicone
Dimethicone functionalised with an amino group, giving a slight positive charge and hair adhesion, or substantivity.
Step 2
Selective Adhesion
Targets areas negatively charged by damage, providing smoothness where it is most needed.
Step 3
Anti-Adhesion Tendency
At low doses in emulsion form, it does not produce noticeable build-up in most cases.
ii. Role in the Formula
How Is It Read on a Label?
Amodimethicone is a dimethicone derivative functionalised with an amino, nitrogen-containing group that gives it a positive tendency. This charge enables selective adhesion, or substantivity, to areas negatively charged by damage. Conditioners, masks and leave-ins use it for smoothness and frizz control. Generally formulated as an emulsion at low doses, its anti-adhesion tendency means excessive build-up is not a common problem.
Typical Concentration Range
Low dose (generally in an emulsion, below 1% active)

iii. Sensitivity Advisory
A Note on Extra Care in Context
The perception that silicones clog pores or suffocate hair needs context. At low doses, amodimethicone's anti-adhesion tendency means it does not build up in most uses. Layering a very heavy silicone routine on fine hair can feel weighty; it is assessed alongside the cleansing system.
A sensitivity advisory is not an instruction for use; where individual health circumstances, pregnancy or known sensitivities are involved, discussing the decision with your doctor may be a more contextual approach.
