Our expert says:
Minoxidil and Propecia are actually the only medications that has been proven to work. You however have to use it for ever - if you stop, the hair would start falling out again. Minoxidil lotion won't really cause any systemic side effects, or rings under the eyes. Propecia may have some side effects but is is not a given that it will cause erection problems or loss of sexual desire.
