This episode explores the science behind postpartum hair loss and reassures mothers about the natural process of hair shedding after pregnancy.

You survived birth, the sleepless nights and the newborn haze. And then somewhere around three or four months in, you reach up to wash your hair and pull your hand away covered in it. It's alarming, and for most of us, nobody warned us it was coming. This episode is for every mum who has stood over the shower drain wondering if something is seriously wrong. It isn't.
