Online consultations have such limitations as discussion about the medications is often incomplete. Minoxidil is for indefinite usage in patients of male pattern baldness as per current medical literature and has to become a part of life, if you wish to have a good hair volume. It gradually enlarges the miniaturized hair follicle to full grown hairs. The first 12 months of treatment is very important and Minoxidil should be continued twice daily or else the expected benefits may not happen. It is a good maintenance drug with minimal side effects.
