Well, he feels strongly against dying my hair during pregnancy and I have read BB threads and magazine articles on the subject. I just want to dye the greys at the top of my head using a root touch up colour that only takes 10 minutes. It isn't like I am soaking my scalp in the dye for a long period of time and I feel like a nanna at 33 with all the greys. The baby mag article I read said that if you have to, only do it once during second and once during third trimester. I think that because this is only a 10 minute treatment and I am not putting dye on much of my scalp that it should be ok....what are your thoughts?
