Minoxidil is the most effective drug for hair loss which does not act on the body’s hormones. It is especially effective for women. Like all medication it needs to be treated with respect and, when used to excess or in some very sensitive individuals, the topical formulation can lower blood pressure.
There have been several reports coming out of Europe of young children getting hold of their parent’s minoxidil liquid and drinking it. As you can imagine they developed low blood pressure and some needed hospital treatment.
The message is to be sure to keep medication out of reach of children.
