I read in what to expect while you're expecting that it ISNT harmful to color your hair...and my brother is in med school and he told me it wasn't proven to be harmful. The only bad thing about coloring your hair while you're pregnant is the hormones in you make it harder for your hair to hold the color. I colored mine with hard chemicals and payed a lot of freaking money and the hair dye didn't take well. Anyways just do what you think is best though...I have heard some sort of vegetable dyes work well(?) |
