Male Baldness Info

Hi,
I am 20 years old , studying in IIT Roorkee. I have been suffering from hair loss (for more or less 2 years). The hair loss seems to be throughout the scalp , but a little more concentrated round th e left parting and the rest like the male pattern baldness of sehwag where only the side parts remain. The middle area throughout has very much reduced hair density now.
I have very curly and at the moment medium length hair and as a result the hair loss can be hidden with some hairstyles. However if i roll back my hair , or while its wet, the scalp is visible from the front.
I am using Clinic All Clear , Hairfall defense shampoo at the moment. Moreover I am originally situated in Delhi.
Please advise me on remedies that i should take and whether i should take steps such as getting hair cut short or shaving my head as well as increasing intake of juice or something.

i wanted to know if there were any homeremedies or natural treatment(i prefer not to use chemical sutff) to stop hairfall especially from the hair on the side of my head,the male pattern baldness area?. if not stop hairfall, is there any easy way to reduce it or lessen it?
