seems like unnecessary dangerous experimentation with the hopes of something cosmetic. why not just color hair?
In fact, hair colors contain toxic harmful chemicals that even increase the risk of certain cancers. I do color my hair, but I don't like it, and I do it as little as necessary.
Because in terms of driving highways are safer (have less accidents) than urban and rural roads, and the most dangerous areas are intersections.
Or if you're a male, why bother with coloring at all? Just own the young silver fox look and rock with it. Or shave it and grow a huge beard. As a male you have a lot of natural workarounds against imperfect hair color..
