Get checked : Hair loss can be quite devastating in your age group. See your doctor as soon as possible and get a thorough work up. Hair loss is common in thyroid diseases and overall anxiety. Your doctor will do a series of tests to rule out many possibilities. He may even ask you to see a dermatologist to make sure you do not have fungal and other skin conditions that may be causing this. All the best.
