When the hormones return to pre-pregnancy levels, that hair
falls out and the normal cycle of growth
and loss starts again.
Some medicines can cause hair
loss. This type of hair loss improves when you stop taking the medicine. Medicines that can cause hair loss include blood thinners (also called anticoagulants), medicines used for gout, medicines used in chemotherapy to treat cancer, vitamin A (if too much is taken), birth control pills and antidepressants.
