Emina,
I was wondering if you are comfortable discussing this health issue with a trusted adult in your daily life? I don't presume to know what level of communication exists in your household. If my daughter was having ANY problems, I would want to know. Have you seen a health care professional about this? There are many reasons for hair loss and many treatments. Fasting is definitely therapeutic for many ailments, but determining the underlying cause is essential to sucessful treatment.
Your body is experiencing it's greatest period of growth and development. This includes your brain, organs, reproductive system, and musculoskeletal system. It's easy for nutritional deficiencies to set your body off balance. Nutritional suppliments are a science and must be studied carefully for benefit versus causing harm. The web is a wealth of knowledge, but also full of people seeking wealth through false information.
You stated you have benn researching hair loss for the last two months. Good for you taking charge of your own health. Your tenacity will serve you well throughout your life. Perhaps someday you will pursue a career in naturopathy, osteopathy, or some other natural health field. Please let me know if I've answered your question; I am a little concerned. Colleen
