First of all congratulations on your pregnancy!
One of the major changes is change with the hair like other parts of the bd.
It could thin or fall out, or it could also thicken.
Understanding why this happens during pregnancy and what you can do to help the problem will help you in fighting the thinning and loss of your hair or with extra hair growth.
Hormones have lot of effects on your hair.
The main reason your hair will change during pregnancy is the change in hormones.
Estrogen plays a large part in the way that your hair is shaped.
If your hair begins to grow faster and becomes thicker, it is most likely because there is an increased amount of estrogen that is moving through your body.
Estrogen moves to the hair follicles in your body to increase the growth rate.
There will also be extra nutrients that are provided from the estrogen increase, which will also increase hair growth.
This is usually a result of the estrogen allowing the metabolism to move faster, which then supplies extra nutrients throughout the body.
