Don’t do your hair when you are pregnant because the potions used to do your hair, such as hair coloring water, perming water and straightening water, will have a certain effect on your body. The body’s resistance is relatively poor during pregnancy, so if you get your hair done at this time, it is likely to affect the fetus, so it is recommended to consider getting your hair done when you are not pregnant. It is also not recommended to wear heavy makeup or tattoo eyebrows during pregnancy, which may affect the fetus in some way. It is recommended that you protect yourself during pregnancy by not breathing second-hand smoke and not drinking alcohol, in addition to eating a nutritious diet and not coming into contact with toxic or harmful gases or objects. This will be conducive to the healthier development of the fetus and eugenics.
