I am red and proud 
I use a bodyshop lip-liner on my eyebrows because I can't find the right shade anywhere else. It's a warm beige with just the right hint of reddishness. Acts just like a brow pencil - has that slight extra softness that helps with application.
I have a smattering of wiry grey hairs silvery tresses, and have found a shade of hair dye that I really like: 'Butterscotch' by Casting. It's supposed to create a strawberry blonde shade, but comes out as a warm mid auburn (on my hair anyway, which is, well, warm mid auburn). Over the counter dyes tend to be much darker than the colour on the box, and this works well, although it could be a smidgeon more vibrant if I'm being picky. Looks natural though.
Would love to hear from other ginges (yes, we can use that word - but the non-red, nooooo!).
