If you're like many women, bleaching, dyeing, or highlighting your hair may be a regular part of your beauty regime. And if you're like most pregnant women, you probably have some hesitation or even a fear about continuing to color your hair while baby is in tow. Although research into the effects of hair coloring on baby's health are still somewhat limited, many experts now contend the dyes are most likely safe and that women needn't be afraid to color their world during pregnancy.
That said, don't be surprised if your doctor still suggests you approach hair coloring with caution. Because the dye is absorbed through the scalp and into the body (it can be identified in urine), some medical experts are hesitant to give carte blanche to hair coloring during all three trimesters. Often, many physicians advise holding off coloring hair with permanent dyes during the first trimester when your baby is undergoing important neurological developments. Coloring can then be resumed in the second or third trimester.
If you color your hair at home, look for products with the fewest number of chemicals and always work in a well-ventilated room, wearing gloves while handling the mixture. If you have your hair done in a salon, request the first appointment in the morning on their least busy day when you are least likely to suffer excessive chemical exposure.
