I go for my 30 wheel appt today & I'll be asking about this. I wanted to wait but my greys aren't being cooperative.
They say it's ok I personally avoid doing things like this
Wait til second or third tri
It's ok but after the first 3 months and as long as you are in well ventilated room.
My ob told me uts ok to dye hair but not bleach.but for me I wait for second tri to color my hair.im 20 wks and 4days now.
