Many women wear makeup, nails, hair coloring, perms, and tight pants on a regular basis, which may not seem like a big deal to women who aren’t planning to get pregnant. However, for the mother-to-be, these beauty initiatives can do more harm than good. First of all, some cosmetics, especially the so-called whitening products, are more lead-containing, if a woman’s body contains a lot of lead, resulting in the birth of a baby with hyperactivity disorder, mental retardation, anemia, the chances of a long time. Secondly, it is not advisable to perm and dye your hair. Many perms and hair coloring products on the market contain a large amount of stupid diamine, which has a great impact on the human body’s hematopoietic function, making people develop aplastic anemia. These toxic substances may enter the blood circulation through the skin, which in turn affects the quality of eggs, and even lead to fetal malformation. Furthermore, wearing tight-fitting pants for a long period of time restricts the body’s movement, which to a certain extent hinders blood circulation in the abdomen and oxygen supply to the internal organs, leading to damage to the uterus and ovaries, causing irregular menstruation, gastrointestinal disorders, and fatigue easily, among other symptoms. Therefore, in order to prepare for pregnancy, it is best to use less lead-containing cosmetics for the health of the fetus and baby, and to do the basic cleaning of the skin. You can’t dye or perm your hair from 3 months before pregnancy to delivery. Wear loose cotton clothes and pants.
