Hair treatments include hair coloring, curling (permanents), bleaching and straightening agents. Low levels of hair dye can be absorbed through the skin after application, and the dye is excreted into the urine.
But, according to the experts at Mother to Baby, “There is no information on having hair treatments during breastfeeding. It is highly unlikely that a significant amount would enter the breast milk because so little enters the mom’s bloodstream. Many women receive hair treatments while breastfeeding, and there are no known reports of negative outcomes.”Despite this good news, if you are still hesitant, you might consider highlights or streaks, as the dye is not placed directly on the scalp.
If you have any questions about breastfeeding, speak with a lactation consultant or email us at AskUs@marchofdimes.org. We are happy to help!
