The grey hairs on my head have finally become so numerous that I'm going to start dying rather than plucking. I got some Naturtint permanent dye and am currently doing a patch test.
I was thinking about putting some on my eyebrows for a minute as a tint after finding a website suggesting this, but the instructions say it's only intended for head hair. I know the skin on your face is more sensitive but can I really not use it?
