If it's going grey in a week then you need to change the type of colour that you are using. Six weeks is the normal time before the grey comes back.
I'm dark but have come up a couple of shades as too dark is not flattering.
When I turned 40 I went blond. Don't know who was more shocked, hubby or me.

Since then I've become more sensible.
A good colour can make such a difference.
