Dimethiconol is a hydroxyl-terminated silicone (a high-molecular-weight dimethicone), usually supplied blended in a carrier fluid.

It is a premium conditioning and smoothing silicone that forms a light, breathable film for softness, slip, shine and frizz control — especially prized in hair care.

Benefits of Dimethiconol

A dependable functional ingredient that does its job elegantly.

Smoothing Film: Lays down a light film for a silky, smooth feel.
