I have noticed the loss of hair, too, after the birth of my child. This could be the result of shifts in hormones from pregnancy. Also, have you had your thyroid checked? One symptom of hypothyroidism is the loss of hair in addition to other symptoms like dry skin, constipation, etc. Note that not all those with hypothyroidism experience the same symptoms. In addition, after pregnancy it is not uncommon for the thyroid to act up. I hope this helps!
