37 here. Embraced the gray for a while, then got a bit sick of it. My next door neighbor happens to be a stylist/own a salon, and she recommended a semi permanent rinse. The nice thing about it is that it does not give me a line when it grows out -- it just fades after 6-8 weeks. So I just start going naturally gray again after a while if I forget/don't have time to go see her. Much better than a line. So far, so good. I am not disciplined enough to get in regularly enough to do a permanent color. I would be the dork with the skunk strip otherwise.
