I am 18 years old and I am doing by B.Tech .I had a long hair when I am in 12th. When I entered to college I gone through a hair cut so that my hair become short. And it started to fall quickly with a 2 to 3 months I lost half of hair and now I am studying 2nd year still it continues to fall. I have found that it is due to weak hair roots. I haven't gone through any surgery ,chemotherapy and I had no such a severe disease and I have noticed that all my hair is from scalp.
