Well that depends again ..temporary or semi-perminent color?...if semi it is doable ... but you know...My natuaral hair color is a dark/medium brown...and I've done silver hair twice on me and a bunch more on my friends... the best temp solution that will REALLY WORK...is a spray...these can be found most anywhere costumes shops, sallys, anyway.... It will turn everything and anything a gorgeous shiny silver gray. Now however if you do want to do a semi-perminent just for kicks and giggles I can tell you how to do that to...but thats probably something I'd im you as I wouldn't want to keep it short on the whole dying process. But like I said I can walk you through it & I do know that the line of toners I use makes a "semi - permanent hair color in 5 shades made specifically to enhance naturally gray hair...they include Pearl, Platinum, Silver, Slate, and Smoke" I also do think that Roux does make a rinse with a silver theme something like...oh heck I'll look..........True Steel & Silver Lining. Now as how well these will work....I haven't actually used a rinse for these because the silver spray works so well. But I would imagine that with your hair type it should get the color you want if you did....I would only worry about the coming out part so you might ask someone at sallys. or a salon.
