Hair powder to cover grey roots?

[fassbender]

Can anyone recommend me something to cover my roots between visits to the hairdresser? I am dark haired and getting greyer, could really do with something - before I pluck up the courage to just go completely grey!

Charles Worthington spray colour is amazing. They sell it in boots in lots of different colours. I haven't needed to colour hair for weeks. I just spray it into parting

Colour Wow Root Cover Up. I get it from my hairdressers, but you can buy it online. Not cheap, though.

I use nice and easy root touch up, I get my hair dyed professionally about every 3 months and get my dd11 to wack this on my parting when the roots start to show after about 6 weeks.then it gets me through to the next dye job. Have tried spray and hair mascara with very poor results.

Thank you! I will look at your suggestions :) Needing to cover my roots after about 3 weeks at the moment :-/
