How can i prevent my hair from falling? they are falling very much.can oil help? if yes, tell me the brand of oil which is very much helpful?

Baldness..: ...Is either from infection, trauma, or most likely, genetic. 18 year old men can begin to have male pattern baldness, and no oil will help with that. In order to determine if it might be something else, a doctor would need to look at it.

Hard to tell: It is certainly hard to say how to prevent hair from falling out. My advise is toast sure you eat a healthy diet and get lots of fluid. While i don't know of any specific oil or ointment to help there are certain medications that my slowdown the hair loss. Propecia (finasteride) is one and manoxidil is another one. Please talk to your doctor first before taking these meds, they do have some side effects.
