Is it safe for us to do chemical treatment for our hair? Rebonding and hair coloring

Although no data is available on women receiving hair treatments while pregnant, it is known that little of the chemicals would actually be absorbed into the bloodstream. BUT if you are hesitant (very good reason to be), you can avoid treatments that involve the scalp because these can be absorbed into the bloodstream and in the long run, affect the baby as well as breastmilk. Alot of mommies choose to avoid such chemical hair treatments till after the birth. Some even wait till they are done breastfeeding. Consider alternatives like having highlights put in your hair because the dye is only placed on strands of your hair and does not touch the scalp. This way, the skin does not absorb the chemicals into the bloodstream. Another alternative is pure vegetable dyes including henna. You could also consider home made natural hair treatments.
