Topical minoxidil used for hair loss lowers blood pressure.

Is it true that topical minoxidil used for hair loss lowers blood pressure?

Partly. The retrieved items only partially address the claim: one pharmacology review states minoxidil is a vasodilator that lowers blood pressure, but in the context of oral treatment for hypertension, while other items on hair-loss dosing (mostly oral) report minimal or no blood-pressure lowering. No item directly measures whether topical minoxidil applied for hair loss lowers blood pressure.
