@rootmd: When Does Postpartum Hair Loss Actually Start? Postpartum hair loss usually doesn’t start the day you give birth. Because of the hair cycle, there’s often a delay of a few months before the shedding becomes noticeable. So if your shower drain suddenly looks a little scary a few months after having a baby, that timing can actually make sense. #PostpartumHairLoss #Postpartum #NewMom #HairLoss #TelogenEffluvium
