Hair Changes

Hair changes are traditionally not recognized as one of the symptoms of pregnancy, but there are hair changes that you may experience during your pregnancy.  Although some women report a sense of hair loss, the more common thing is a sense of hair fullness.

What causes hair changes during pregnancy?

On a daily basis your hair is falling out and being replaced by new hair follicles.  Your pregnancy related hormones typically cause your hair follicles to remain in a resting state which prevents them from falling out.  This leads to a sense that your hair is fuller.

When do hair changes occur during pregnancy?

Your hair changes are usually most noticeable in the second or third trimester.

How frequently do hair changes occur?

Hair changes are not traditionally recognized as a symptom of pregnancy, so there is little research on the percentage of women that experience hair loss or hair fullness.
