What causes less armpit hair during pregnancy?

Everyone has armpit hair, but some people have more armpit hair, while others don't. This is generally related to physical conditions.

What causes less armpit hair during pregnancy?

Generally speaking, a woman's armpit hair will not change after pregnancy. If it decreases, it is best to go to the hospital for a check-up to find out the cause and receive symptomatic treatment. The thickness of armpit hair is related to one's own hormones.

Why does pregnant women lose body hair?

Changes in pregnant women's body hair are related to hormone secretion in the body.

The growth of human hair is mainly controlled and restricted by androgens and estrogens. After a woman becomes pregnant, the hormones in her body will undergo major changes. When the male hormones in the body take over, the body hair will increase. On the contrary, if estrogen prevails, the hair on the pregnant woman's body will become less and fall off on its own. After the baby is born, hormones return to normal and body hair will grow again.

Common changes in body hair during pregnancy

Generally speaking, after pregnancy, women will experience changes such as more hair, lighter eyebrows, less armpit hair, and more sweat hair. Among them, the increase in hair and less armpit hair will make pregnant women very happy, but the obvious increase in body hair, such as on the arms, around the belly, on the calves, etc., will make pregnant women crazy. In addition, many women will grow new hair on their faces during pregnancy. They will also grow a lot of hair around their breasts, near the midline of pregnancy in the abdomen, and on their backs, which can even be clearly touched.

Pregnant women don’t need to worry too much about the increase in body hair, nor do they need to undergo hair removal treatment, because the hair will fall off automatically within 3-6 months after delivery as the hormones in the body return to their pre-pregnancy state.

Is it accurate to judge the gender of a woman by her body hair?

Inaccurate.

Rumor: If a woman has more body hair during pregnancy, she will give birth to a boy, and if she has less body hair, she will give birth to a girl.

Scientific explanation: This statement has no scientific basis and is not credible. Because the changes in pregnant women's body hair are mainly related to the level of androgen and estrogen secretion in the body, and the secretion of androgen and estrogen is determined by factors such as mood, nutritional status and external environment, and has nothing to do with the gender of the fetus. Therefore, it is not reliable to judge the gender based on the changes in body hair.
