Is there any store bought hair color or highlights that i can use while i'm pregnant?

i'm seven months pregnant and i can wait to color my hair, but i was just wondering if there was any hair dyes or highlights(blonde) i can use that won't harm the baby. any ideas?Is there any store bought hair color or highlights that i can use while i'm pregnant?
The suggestion is not to use a permanent dye in the first three months (for fear of dye entering the body through the scalp). Instead, use a rinse or other less permanent color during this time. Another option for you is to use highlights instead of a permanent color until after you have delivered the baby, because the dyes do not go into the scalp itself.
