Hi Rahul.. From the above presentation and treatment i assume the diagnosis made is of Androgenetic pattern hair loss.Two medications are approved to treat male pattern baldness: 1)Minoxidil: is a solution that you apply directly to the scalp to stimulate the hair follicles. It slows hair loss for many men, and some men grow new hair. Hair loss returns when you stop using this medicine. 2)Finasteride: is a pill that interferes with the production of a certain male hormone linked to baldness. It slows hair loss. Hair loss returns when you stop using this medicine. So you are definitely in the correct path.However what you have to understand that a genetic pattern hair-loss will never have a complete cure.There are a number of other therapies available too, however none of them have been proved to be effective or are FDA approved. Some dryness and scaling of the scalp is common after using Minoxidil due to its vehicle.U can add on Ketoconazole shampoo 2% thrice weekly to shampoo your hair.This keeps you dandruff free. Ketoconazole shampoo is frequently used as an adjunct to other hair loss treatments. It is a mild anti-androgen that may possibly block DHT (the hormone that causes hair loss) at the scalp. The shampoo itself also helps maintain a healthy scalp, which is important when treating hair loss. Hope this helps..Take care!
