If you need help I recommend you type in the specific question you need help with
I do not believe that cyclopentasiloxane is bad for your hair. Case in point, I've been using conditioners that specifically include this ingredient because it conditions THE BEST and leaves absolutely no knots in my hair. Only a little bit of conditioner is necessary when using this ingredient as it spreads so easily that a tiny bit is all you need and you never ever have to leave it in your hair for any amount of time for the conditioner to work! My hair comes out soft, manageable and shiny. Problem is, you won't find this ingredient in less expensive products (Suave doesn't include it in their products as far as I know).
it is very harmful or harmful depending on your body
It is not harmful to animals but it can be harmful/fatal to children
