I am a student and currently I am suffering from hair fall problem. Till first two years of my engineering it wasn't this serious but as I moved in hostel in my 3rd year it started falling more rapidly. Now my hairs are thinner and density is less. Also as I am student I can't afford to expend much on my hairs treatment. I don't know what's wrong now whether its because of hostel water or mess food. How to reduce the hair fall and increase the density again?
