I had my mom do mine (she's a pro) with the oila stuff cuz its ammonia free..didn't take evenly.
It's okay to get your hair dyed just do it in a well ventilated room and try not to get the hair dye on your scalp. The color may not come in though idk why but it's common.
Your fine I dyed my hair all the time with all 3 of my kids , the smell just might bother you more so open a window that's all
Just test the color first to make sure that the color will come out the way you want it to. Also make sure you're in a ventelated area, but es, it's safe. My hair dresser said that she dyed her hair so much with her daughter Violet that she was going to come out violet, lol. Her babies are 100% healthy. Getting your nails done if fine too. :)
I heard the color won't come in
It's safe! Just dye your hair in a big, ventilated room. Somewhere with a window open or something. Getting your nails done is also safe. Just try to go to the nail salon when it isn't too busy. It won't smell as bad then haha.
