hello Arun, welcome to HCM Androgenic Alopecia is the most common cause of hairfall in males of your age...It is a genetically determined progressive disorder characterized by the gradual conversion of thick terminal hairs into vellus i.e very thin hairs and eventually baldness... Minoxidil and finasteride(same as finpecia) are the only approved and time tested medications available for the condition. So, your doctor had made a right choice in prescribing the medicine... As minoxidil usually present as an alcoholic solution so it may cause itching and dryness on continuous use..To combat it you may use gel based/ foam based /alcohol free minoxidil lotion... You may get PRP scalp therapy if the above treatment is not benefiting you as desired... thanks
