What is minoxidil, and how does it work (mechanism of action)?

Minoxidil is a drug that is used
for treating male-pattern baldness and hair loss in women. Oral minoxidil was
originally used for treating high blood pressure, but patients and health care
providers noticed that hair growth was a side effect of treatment. This led to
the development of topical (solution applied to the skin) minoxidil for the
treatment of male-pattern baldness. The mechanism of action leading to growth of
hair is unknown. The FDA approved minoxidil in August 1988.

What is the dosage for minoxidil?

Minoxidil should be applied as 1 ml of solution or
half a capful of foam to dry hair and scalp once in the morning and again in the
evening. It should be spread evenly over the affected areas, and then the hands
should be washed with warm water (if the hands are used for application).
Minoxidil must be applied on the scalp at least twice daily and for at least
four months to see results. Minoxidil works less well in patients that are
older, have larger areas of baldness, and have been bald for longer periods of
time. Minoxidil should be applied to a dry scalp only, and left in place for at
least four hours. Minoxidil must be continued in order to maintain or increase
the hair growth achieved.

Which drugs or supplements interact with minoxidil?

Minoxidil should not be used with other topical medications because they may increase its absorption and side effects.
