Minoxidil has a half-life of about 4.2 hours in the bloodstream after oral administration. However, when applied topically, as is common for hair loss treatment, it has minimal systemic absorption. This means very little enters the bloodstream, and it's quickly metabolized and excreted. Most of it leaves the body within 1 to 2 days after stopping use. But, the effects on hair growth may last longer due to its action at the scalp level.
