I think the thing to keep in mind with silicones is that you dont over do it. I use them when I need them and not when I dont.
Winter time for me is easy to follow CG but summer is very challenging for me with frizz. I try to keep the silicones to stylers and maybe a conditioner. It leaves me having to wash daily or most days at least. I do think you will see the effects of silicones if you use them long term. Actually I dont think its the silicone as much as the shampooing to remove them.
I say use them when you need them and go back to CG when you dont.
