I am 5 months pregnant, and I was just wondering if it is safe to use the hair coloring kits that you can buy at the store. I want to dye my whole head blond. Also, my hair is light brown with dirty blond highlights, so with my highlights it looks blonde, you can barely see the brown, and everytime I have used those kits to dye my hair blond it turns orange. I follow the instructions, so I don't understand why it does this. Does anyone have any advice on that??? Thanks so much!!
