Minoxidil is a medicine used in the management of pattern hair loss. Topical minoxidil is applied directly to the scalp and is available over the counter in Australian pharmacies. Low dose oral minoxidil is also used for hair loss and is prescription only.
Minoxidil supports hair growth while it is being used, and shedding can resume when treatment stops, so it is prescribed as part of a long term plan. A doctor reviews blood pressure history and other medicines before considering the oral form.
