Hey Michele! My first appointment is the same day as yours. This will be our first, so I know I will be very apprehensive when I go. I found info at americanbaby.com about the safety of coloring your hair. Here is what it says:
"Is Hair Coloring Safe?
During your pregnancy, you're bound to have many concerns about how your lifestyle, or certain substances you're exposed to either at home or work, could affect your baby. Here are answers to some common questions.
There's no proof that the chemicals in hair dyes cause birth defects, miscarriages, or any other complications -- nor are there reliable studies that prove these substances are safe. Because we don't yet know enough about these chemicals, some doctors say that pregnant women should avoid hair dyes (or at least minimize their contact with them), especially during the first trimester.
Highlighting or streaking your hair, both processes that involve less scalp contact, may be safer. Vegetable-based products, such as henna, are also considered safer. If you decide to color your hair yourself, wear plastic or latex gloves to minimize absorption of the chemicals through your skin, and don't leave the product on your scalp any longer than necessary."
I hope copying and pasting this here is okay. Somebody let me know if it's not please.
