(Silicone, Cationic)

PURPOSE: 

Dimethicone allows hair strands to move easily past one another.

IMPLICATIONS:

This ingredient it is very hydrophobic, so once on the hair shaft moisture may not penetrate the coating and thus make the hair dry. It is also difficult to rinse away from the hair shaft, requiring a detergent to remove. You will need to use a clarifying shampoo to remove it if it's used in your leave-in products.
