Um... I'm a guy and I color my hair using Just for Men. I do it myself at home and it can be messy. However, it's very inexpensive -- a $7 package lasts me for three coloring sessions, or about nine weeks before I have to get a new package. The darker the shade, the more likely it will stain your skin and make an obvious mess.

The color works well, though. It's natural looking and most people think I'm 10-15 years younger than I actually am. (A pretty co-worker thought I was nearly 20 years younger!) I decided to use it when I went job hunting four years ago and didn't want to look like I was on the verge of retirement. I got a very good job that pays beyond what I ever thought I'd make, so maybe the hair color was a good idea.

That's a man's view on the subject, anyway.
