Treatment for hair loss in men can be done by the use of Finasteride and Minoxidil which is also known as Rogaine. The two are clinically proven drugs that treat the hair loss to varying degrees. The individual in question can also add more mineral supplements in the diet such as calcium, magnesium and zinc along side eating green leafy vegetables. Contact a doctor for prescription depending on what is causing your hair loss.
