I wanted to say that I finally tried the just for men beard and moustache dye on my white stripe in January and it works great. My white hairs are shiny diamond white, so I figured I'd get better results w/ the beard/moustache dye. The first time it didn't take well and faded in 1.5 weeks, but the second time lasted about 5-6 weeks. I tried medium brown and it's a very good color match for me. It's super easy to do since you just blend a bit of developer and a bit of color, mix it and then brush it on with the provided brush and you only mix what you need. I've spent the last three weekends out working in the yard though and my hair is already getting sun bleached, so I'll have to pick a golden color for next time. Anyway, I think it's a good option if you have just a little area around the temples or crown that you want to color because it's easy, no waste, and you don't subject the rest of your hair to the damage some hair dyes can do.
