I was just reading up on dermmatch. They will send you a free extra shade after you get your first one, so you can mix them. And there is a money back guarantee that includes shipping. That takes the risk out. So the only reason not to try it is it just sounds so hard to believe. I'm sure if someone is NW5 and very thin, it would look good, expecially for work. But since my scalp is just showing a bit, I wonder if it is worth the hassel for me, and if it will be noticed, or it it will rub off on a woman playing with my hair. If you can't let a woman play with your hair, they you might as well stay single. I love it when my hair is played with.
