Which hair color brand is best to cover up sparkly grey hair?

I need to color my hair again! Bu my problem is that I have sparkly grey hair strands that I can't get hair color to cover up.





Maybe if I got a permanent one it would work or just a dark hair color. But which brand should I get?Which hair color brand is best to cover up sparkly grey hair?
You should dye it a dark brown or black.Works wonders on grey hair.I would try the Loreal one.Thats good.My mum uses it.
