Pretty quickly. I got my hair done on Feb 13th. This is a photo that I took on the morning of the 14th. The color is accurate. My hair was RED.
I wash my hair almost every day, however the visible red “wash out” stopped after my second shampooing, so who knows. Nearly 3 weeks later, here’s where my hair color sits. Based on the last go-round with the dye job, it’ll stick at about this color indefinitely.
Sorry about the weird myspace angles. I was in the car and I am the master of taking awkward selfies.
