Silicones are not usually charged, but stay on the hair because of their incompatibility with water. If you put a drop of silicone in water, it will not dissolve, no matter how much you stir it. When a silicone product is put on your hair, it deposits and resists being washed off.
DETERGENTS ARE NEEDED TO REMOVE THEM
Since silicones and polyquats stick to hair, they need more than just water to remove them. In fact, silicones can stick to hair so well that they may require multiple shampooings before they are removed. Similarly, some polyquats may be difficult to remove from hair. While a sulfate shampoo isn’t required to remove them, sulfates are your best bet.
BOTH MAY BUILD UP ON HAIR
Depending on the type of molecule, both silicones and polyquats may build up on your hair. Dimethicone is one of the most difficult silicones to remove and multiple use of products with it can make your hair look dull and weighed down over time. Cyclomethicone, on the other hand, evaporates from hair like water and will not cause the same problems. Polyquats do not build up as much, but still require occasional washing with a polyquat-free shampoo.
