Minoxidil is available as a lotion, that you must rub on your scalp every day. It is available in pharmacies without a prescription. It is not clear how minoxidil works, but there is evidence that it causes hair growth in most men.
The medication contains either 2% or 5% minoxidil. There are indications that the stronger (5%) version is more effective. From other evidence, it appears to be more effective than the 2% version. However, the stronger version has more side-effects mainly itching and dry skin.
Like Finasteride, Minoxidil is used for several months before any effect is observed. The balding process will resume when discontinuing the treatment with minoxidil. The transplanted hair will fall after approximately two months when the treatment is stopped. Side effects are uncommon.
It is the only drug currently available to treat female pattern baldness.
One in four women who use Minoxidil lotion will grow hair, and it slows hair loss or stop at other women. In general, women respond better to minoxidil than men. Hair growth products should be used for a number of months in order to see any effect.
