Thanks for posting your query. You are on oral contraceptive pills
which could infact increase the hair growth. only anti cancer
agents produce sudden hair loss. Hence you may continue your medication as per advice and at the same time get investigated for hair loss like thyroid function tests
and serum ferritin levels as you may be anemic which could be the cause of hair loss.
please check with your doctor and if possible a dermatologist
for examination of hair under microscope to know at which stage the hairs are falling?
