Pregnant women are often given advice on pregnancy from how to have a healthy pregnancy to what to avoid. For those who change their hair often, there is advice against dying hair during pregnancy. This advice is well-intended and often due to there not being enough research to determine something to be perfectly safe for the baby and expecting mom.
Should You Dye Your Hair While Pregnant?
The reason research about this topic is minimal is because studying any potential negative effects of hair dye on pregnant women and fetuses isn’t exactly easy. A well-designed study would require one group of pregnant women not using any dye and another group with regular and/or long exposures to hair dye to see if there is an increase in adverse effects among the latter group. Let’s face it, if there is any possibility that a substance could reach a growing fetus and jeopardize their health or cause harm to even one fetus, no one will be on board.
When it comes to dying your hair while pregnant, this is due to the effect of the chemical components, such as ammonia and peroxide, are understandable; and synthetic fibers the make up the hair dye which leads most to say that dying your hair not good while pregnant. Synthetic components such as dihydroxybenzene which is put in both permanent and semi-permanent dyes by the manufacturing companies. It is unclear the extent that dyes are absorbed into the body after being applied, a cut or scrape can increase absorption. There have been a few studies linking the use of hair dye to an increased risk of certain types of cancer, but there are also studies that have found no connection at all.
Many pregnant women are given the advice to wait to go for a hair dye treatment after the second trimester, giving time for the fetus to undergo development and not be as vulnerable as in the first trimester.
