My last effort to blue my own hair worked, but was also a huge pain in the ass and made a bit of a mess. Plus, I really didn't do that wonderful of a job with it.
Rachel was pretty excited with the prospect of getting to do my hair. She isn't a hair stylist or anything like that, but as an artist has a pretty amazing ability to visualize colors, textures, and the like.
And of course from my own point of view, the worst thing that would happen is that I'd have to wait for my hair to grow back out.
Thankfully, however, that won't be necessary as she did an absolutely spectacular job. ...despite the fact that I only had a full sized paintbrush and baking foil instead of the much thinner aluminum foil sheets (typically used for hair coloring).
She's been reading up on how to properly bleach hair that's already been colored with blue dyes and I'm guessing that project is around the corner.
