Heparin-induced thrombocytopenia (HIT) occurs in up to 1% of patients receiving unfractionated heparin. HIT may occur even when very-low-dose heparin (eg, used in flushes to keep IV or arterial lines open) is used. The mechanism is usually immunologic.
The hair loss can seem more extreme if your hair grew much more than normal during pregnancy, or if you have long hair. Most women will return to their usual hair growth cycle within six months, or between 6 and 12 months after birth.
Some babies will have very little hair when they are born while others will already have heads covered in hair. Infants will also lose all the hair they had at birth within the initial 6 months of their life. Sometimes this hair will grow back, though it will have a different texture and color than it did initially.
