#9- Color your hair when it looks like a bald spot

It's probably a good idea to color your hair when the back of your head looks like it has a bald spot. Not many people have had the courage to tell me this, and my husband doesn't count. However, a number of years ago I was due for a color and I definitely knew it was so when a 4th grade student commented on the bald spot on the back of my head. Not what you want to hear. So every 3 1/2 weeks it's me and L'Oreal!
