I've got a few grey hairs at the front of my head / crown area, mainly one one side. I have long dark hair and they are definitely noticeable in some circumstances eg hair up.
I don't think I want to dye it as most of the time my hair is down and it's not massively noticeable plus I'm in the house most of the time but for occasions when I want to cover those few dark hairs what's the best thing to use.
I've seen spray on products, powders and mascara type things but wondered what is best to go for?
