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.
Typically, a hair is in the anagen phase for two to four years, then enters the telogen phase, rests for about two to four months, and then falls out and is replaced by a new, growing hair. The average person naturally loses about 100 hairs a day.
