Haha, you should see me. I am 75-80% grey and I've often looked for something that will dye my hair grey just to "get it over with".

I've checked every store I shop in that carries hair care products and have not found a colorant that will do grey.

Maybe you and I are the only ones who WANT to be grey

Unless someone comes up with something I've not found, then you just let it grow out.
