As it stands today, there are not many options for silicone alternatives that provide the same anti-frizz, slip and shine benefits on the hair without being heavy and leaving the hair flat. Though silicones are synthetic as opposed to natural or naturally derived, when used at optimized and calibrated levels (which is how we use them), they are the best performers on hair for anti-frizz, slip and shine without leaving the hair greasy or flat. There are many different types of silicones. Some are heavier and more coating, while others are lightweight and do not build up. Amodimethicone, found in many of the conditioners and masques, for example, is a lightweight, water soluble silicone that rinses clean from the hair while providing slip and smoothing benefits.
