Sometimes we put up walls not to keep people out, but to see who cares enough to break them down.
I don't think there's anything out there yet, but who knows what will be available in the future. There are color products that last for a number of washings and then gradually come out, or there are dyes that you can use to keep your hair the normal color. Mine? I let it be gray--I feel like I've earned every last one of them!!!! LOL
