The way pregnancy affects a woman's body goes beyond weight gain or abdominal bulk. During pregnancy, in addition to the emotional changes, there are physiological and physical changes that can lead to stretch marks, skin blemishes, oral problems and even changes in the woman's hair.
The changes in a pregnant woman's hair are mainly due to hormones, as these acquire levels typical of pregnancy. In addition, women may also notice changes in their hair postpartum, until hormone levels become regular again in their bodies after giving birth.
The different sections of this article have been assembled into the following table of contents.
Pregnant women may notice differences in their hair (and nails) due to the hormonal changes that occur during pregnancy. A woman may notice her hair is fuller, shinier and healthier from the second trimester of pregnancy onwards.
This improvement in pregnant women's hair is mainly due to the increase in estrogen levels, which favor the anagen (growth) phase of the hair and, therefore, delay hair loss. Thus, there is less daily hair loss than when a woman is not pregnant, so the hair will be thicker during pregnancy.
On the other hand, pregnant women may notice an increased production of oil on the scalp. If your hair was dry before pregnancy, this will be beneficial and your hair will be shinier and healthier looking. However, if the pregnant woman had normal or oily hair, she may need to wash her hair more frequently than usual and with appropriate products.
Likewise, there are women who notice how their hair changes texture during pregnancy, going from curlier to straighter hair, or vice versa.
After childbirth, the woman regains her pre-pregnancy hormonal status. As a result, the normal pattern of hair loss returns and the woman may notice her hair falling out more than usual. This is known as postpartum telogen effluvium.
This is normal and temporary in the postpartum period. The hair that during pregnancy remained in a prolonged growth phase due to the increase of estrogens typical of pregnancy, will fall out at the same time.
However, about six months after delivery, this heavy hair loss should slow down and resemble the normal hair loss before pregnancy. If the abundant hair loss continues after this time, it would be advisable to consult a dermatologist, so that he/she can make an assessment and check if there is another possible cause.
There are several things a woman can do to take care of her hair during pregnancy and especially postpartum. Among them we can mention:
Finally, one should not hesitate to consult a dermatologist if any of the changes in the hair during pregnancy or postpartum are of concern to the woman.
During pregnancy, the scalp may have increased sebum production and the hair may become greasier.
If the pregnant woman already had greasy hair before pregnancy, she will usually have to increase the frequency with which she washes her hair and, therefore, she should use a gentle and frequent use shampoo adapted to her hair type, but which does not contain many chemicals, as they may not be safe during pregnancy and, if in doubt, consult a specialist.
Most studies indicate that colorants and hair dyes do not harm the fetus or affect fetal development. However, as a preventive measure, many women prefer to use natural hair dyes or temporary hair colors, which do not penetrate into the cuticle layer, allowing only a coating action. Others prefer to avoid hair dyes until the end of the first trimester, which configures the most vulnerable period for the fetus.
If you are pregnant, you may also have noticed changes in your skin, such as the appearance of dark spots. If you want to know more about them, you can read the following article: Why do skin spots appear during pregnancy? How to avoid them?
