Hi. As per your photo, your hair look fine. It's normal to lose up to 50 to 100 hair per day. Don't worry, looks like you r over anxious. You can be treated with some hair specific vitamins. Visit a dermatologist so that necessary medication may be prescribed. Helmet does not cause hair loss. Even if it does, it's better to be bald and alive than hairy and dead. Let me know if you need any further assistance in this regard. Take care Govind S Mittal Bangalore.
