Welcome aboard, Bumble!
I was also a reddish ginger but, over a decade or so faded to a sort of pale honey-blonde which, in all honesty, I rather liked.
But around a year ago, I realised the blonde was getting paler and a bit dingey-grey. This was very depressing as my grandmother, who had the same colouring as me, went a very glamorous silvery white in her sixties.
Then someone told me about Superdrug's Colour Effects shampoo-in conditioner. I use the Strawberry Blonde about once every 10 days and I'm delighted with the result. The depth and intensity of the colour depends on how often you use it and how long you leave it on your hair. And, if you hate it, it'll fade in a couple of weeks.
Highly recommended!
