Question: are water soluble silicones bad for hair?
Answer: Water-soluble silicones are kinder to locks as they wash out easier and don't leave a heavy build-up behind. ... If you choose a non-water soluble silicone, you'll definitely need to use a clarifying sulfate-based shampoo to remove it. Amodimethicone is very common in leave-in conditioners and can weigh the hair down.
