This question is for my fellow experienced moms. i have a question in regards to hair dye, i'm 29 and have a head full of grays so i'm having a difficult time. I asked my OB if its safe to dye my hair he besically told me that there's not enough studies to show that hair dye hurts the baby in anyway. Have you used hair dye products in the past while pregnant. does vegetable dye last and looks like normal hair dye?
