Josh the Red

So my lovely wife has been subjected to about 10 years of me talking about wanting to color my hair red (just for fun). This year, for my birthday, she finally relented and embraced the redness. I'd always intended it to be a bit more drastic, but this is probably the more mature (if that's even possible here) way to go about this. I'm assuming a lot of this will wash off later, even though they CLAIM it to be 'permanent'. If it lightens up too much, I may do it again... Maybe a less 'natural' shade next time. :)
