Hair dye help!

[divergirl]

I have been in hospital for nearly two weeks but should be out in the next few days. Totally unexpected stay and as a result I have missed a number of things including my all important Xmas haircut. Hairdressers is now too busy for me to book something in at the end of this week and will then be closed until into the new year.
I usually have a cut and a semi permenant root colour every 5/6 weeks. I now have a lovely grey line of root showing. I've never coloured my hair myself, any suggestions on something semi permenant that I could use to get me through until I can get a proper appointment.

Should have added that my hair is a mid brown colour

I use Nice & Easy root touch up for this - it's pretty good.

Thanks for your advice, still in hospital but will try this when I get out. 😀
