Tugain Men 5% Solution is a combination of two medicines: Minoxidil and Finasteride, which treats hair loss in men. In men, the balding scalp contains small sized hair follicles along with increased levels of a male hormone that is believed to cause excessive hair loss and retards hair growth. Minoxidil is a vasodilator, which means it widens the blood vessels and provides better blood flow to the hair follicles. This prevents hair loss and stimulates re-growth resulting in longer, thicker and increased numbers of hair. Finasteride is a 5-alpha-reductase inhibitor. It blocks the production of a male hormone in the scalp that stops hair growth, thereby reversing the balding process and preventing further hair loss.
