It is important to know whether your hair loss is actually normal or excessive. It is quite common to lose about 50-100 strands of hair each day and anything over 100 is considered excessive. The cause of a sudden excessive hair loss can be investigated with a careful history, examination of the scalp and some blood test. Before seeing a doctor, it may also be useful to take photos of how much hair you are losing a day so that you can show the doctor.
Furthermore, it is important to let the doctor determine whether your hair loss is a result of some acute and reversible hair loss or general hair thinning. Like what Dr Theng said, you will need to see a dermatologist to exclude other underlying causes of hair loss before deciding if you are actually having female pattern hair loss as hair thining over a long period is different from sudden hair loss.
Hair loss treatment varies from topical treatments, medication to surgery. However, you need to investigate and diagnose what your hair loss is due to before knowing how to treat and the pricing.
