Hair loss: when does it stop?


So I have exclusively breastfed my son from birth and the postpartum hair loss didn’t start until he was about 3 months old. My son is now 5, almost 6 months old and I’m still loosing huge clumps of hair like I can’t believe I don’t have massive bald spots. Is anyone else still loosing large amounts of hair? What can i do to stop it from falling out? I’d prefer not to be balding in my early 20s 😅
