It's fine. I'm a hairdresser...I specialize in color. I colored hair through both of my pregnancies, including coloring my own hair. The kids don't have 2 heads or anything<img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/lol.gif" style="border:0px solid;" title="lol"><br>
I nursed my son for 2 years.....never changed my job and continued to color my own hair as well. He's a big healthy 4 year old!
