Personally I wouldn't do it, not with chemical dyes. Believe it or not your hair is actually living, those hairs have their own circuitry going on and it is well attuned/rooted with the whole of your body as well as the environment. There is an alternative to chemical dye I highly recommend trying at least once in your life, that is henna. It is super awesome healthy for hair and skin, 100·/. harmless, no bad smell, and I promise you will look the best and feel the best + your hair will love you for the rest of your life.
yes just make sure you are in a well ventilated room so you don't smell the chemicals and try not to get the dye on your scalp get as close to the roots as possible though . @afa2015
its fine to color/bleach your hair just make sure you are in an open area and have a fan in there blowing out the chemical smell..the chemicals will not harm your baby so dont worry :) @afa2015
Bleach only if it is ammonia free. Dying with semi permanent dye in a WELL ventilated area is okay. I used to dye my hair outside with a fan blowing on me.
