CoileenDimethicone
What it is
A synthetic silicone polymer used as a conditioning and smoothing agent in shampoos, conditioners, and styling products. It creates a silky, slippery feel on the hair.
Why it matters for curly hair
Dimethicone coats the hair shaft in a waterproof film that blocks moisture from penetrating the cuticle. Over time this leads to dry, brittle curls that feel soft to the touch but are starved of actual hydration. Because it is not water-soluble, dimethicone can only be fully removed with a harsh sulfate shampoo, creating a cycle of buildup and stripping that damages curl pattern.
