Hi. You may be suffering from female pattern hair loss or telogen effluvium. This could be related to anemia, thyroid problem, environmental factors , pollution, stress, junk food and poor diet. You'll probably need treatment with hair care lotions or serums - something that has vasodilator properties and improves thickness of hair and reduces hair loss. Have a good balanced nutritious diet and probably a three month course of hair specific vitamin supplements. See a dermatologist near you. Hope this helps. Let me know if you need any further assistance in this regard. Warm regards.
