Pregnant women are not recommended to perm their hair throughout their pregnancy, especially during the first three months of pregnancy. Hair dyes contain a lot of chemicals and heavy metals, such as mercury, lead, etc. These chemicals and heavy metals are absorbed through the blood circulation and transmitted to the fetus through the placenta, which has a teratogenic effect on the fetus, so it is not recommended for pregnant women to perm their hair. The skin care products for pregnant women throughout pregnancy need special attention, the general skin care products containing chemicals are not recommended, pure natural plant skin care products pregnant women can use, I hope pregnant women keep this in mind to give birth to a healthy baby.
