Yep this is not-quite-a-holy-grail-but-almost conditioner for me! It's the best I've found from what's available in the UK and it is my no-fail conditioner. Everytime I use it my curls come out well moisturised, soft, shiney and well formed. Simethicone is water soluble. I think the US ingredients are diff to the UK but if they're not I hope you love it too!
(And I say it's not quite Holy Grail material as...well it doesnt make my hair SUPER shiney and doesn't leave my hair ENTIRELY frizz-free but I think these are unobtainable quests for my hair, so it is pretty much faultless for me
