Postpartum hair loss — what is happening and when it ends
Handfuls of hair two to four months after birth is normal and alarming. Here is the mechanism, the timeline and when to see a doctor.
During pregnancy, high oestrogen keeps many hairs "parked" in the growth phase (anagen) longer than usual, so hair looks thicker and sheds less. After birth, hormones fall quickly, those hairs enter the resting phase (telogen) together, and shed together about two to four months later. This is postpartum telogen effluvium.
When it ends
Shedding usually peaks around months three to four and then eases, with hair returning to its previous density within six to twelve months. The follicles are not damaged — they have simply reset their cycle at the same time.
What actually helps
- Enough protein and iron. Blood loss at birth and breastfeeding raise requirements, and low iron is linked to shedding that lasts longer than it should.
- As much sleep as you can get, and less stress — easier said than done.
- Avoid tension on the hair, like tight ponytails, while it is fragile.
When to see a doctor
If heavy shedding continues beyond twelve months, if hair falls in patches, if the scalp is itchy, red or sore, or if you feel very tired or your weight is changing quickly, see a doctor to check thyroid function and iron levels. Both are common after birth and both are treatable.
Note: U-TURN is not recommended during pregnancy. If you are breastfeeding, ask a doctor or pharmacist before taking any supplement.
