Hair loss slows down during pregnancy so your hair gets thicker. This is due to an increase in various hormones (progesterone, oestrogen, prolactin)2. These stimulate the growth (anagen) stage of the hair. As a result, hair lasts longer.
Some expectant mothers notice this change in their hair as early as the first few months of pregnancy. The effects are temporary3, however, as after pregnancy the amount of oestrogen drops back to normal and the rate of hair loss goes back to normal.
So even if Mother Nature has given you a helping hand for nine months, you should make sure you continue to look after your hair once baby arrives. Read our tips on how to avoid hair loss after pregnancy.
