Hello, I've met the point now where greys seem to appear after a week of having my hair coloured (yes it grows fast) and really it needs doing every 3 weeks, but its so expensive. Of course the greys are all around my part and hair line 
Does anyone have anyways they try to keep greys masked in between colour treatments?
I read somewhere about some a aveda shampoo and conditioners helping give temporary coverage.
Thx
