Can a pregnant woman dye her hair, and is that safe for the fetus?

Most studies have proven that hair dye during pregnancy is safe. The American College of Obstetricians and Gynecologists has confirmed that there are no negative effects of dye on pregnancy because the chemicals in it do not enter the body significantly through the skin, and hence, their effect will be low on Fetal growth.
On the other hand, some studies have warned of the danger of using the dye on the fetus, especially during the first trimester of pregnancy.
So, my friend, here are some tips that you should follow if you are pregnant and thinking of using the dye:

1 Do not use the dye during the first three months of pregnancy.
2 Do not use the dye if you find cracks in your scalp.
3 Use vegetable hair dyes such as henna, as they are safer than chemical dyes.
4 - When you put the dye on your hair, make sure that the place is well ventilated.
5- Do not leave the dye on your hair more than the specified time.
6 - Wash your scalp well after dyeing.
7 - Use gloves when using the dye to reduce the area of ​​skin exposed to the dye and thus reduce the amount of chemicals absorbed.
8 - Try to avoid putting the dye on your scalp, and you can do this by putting olive oil on the scalp or ear to avoid putting the dye on them...
And enjoy my friend a new color sparkling for your hair.
