Is Weight The Cause of My Hair Loss?

I am 21 years old girl. My hair were extremly good, thick, heavy two years back. My friends used to make fun of me that I used to wear a wig. Then I had two operations (teeth and rhinoplasty). For one year nothing happened but then my hair started falling. I had a haircut and it made my hair look better. But even then my hair continued falling and is still falling out.

I have one more problem, I am underweight. My height is 5 ‘7 ” and my weight is 47 kgs (104 lbs). I eat potatoes etc but dont put on weight. Is this the cause of hair loss? My hair is exposed to the sun for most of day because I am an university student. But I am sure its not the reason because I know many people who work in sun but dont affected. Please help me for that. Can you please give me advice that I can make up at home. I dont wanna go to parlours at this age. Plus please mail me the solution preferebly

It sounds to me that you might have either a medical condition (disease) causing the hair loss and possibly the low weight as well, or a dietary/eating disorder. You need a good doctor to evaluate your overall health. Malnutrition, although rare in the United States, is seen with Bulimia. In foreign countries where adequate vitamins and nutrition are problems, hair loss is seen with some frequency. You need to get a good doctor and get to the root of your problem.
