Minoxidil is vasodilator—originally developed as an oral medication to treat high blood pressure.
During clinical use, patients began experiencing unexpected hair growth.
That side effect is what led to its use in hair loss today.
Minoxidil works by:
*Dilating blood vessels → improves blood flow, oxygen, and nutrient delivery to the follicle
*Prolonging the anagen (growth) phase
*Increasing follicular size in miniaturized hairs
*Supporting cellular activity within the dermal papilla
It does not correct the root cause of hair loss (hormonal, metabolic, inflammatory, etc.)
👉 It supports the follicle—it doesn’t fix the system.
TOPICAL vs. ORAL (SYSTEMIC)
Topical Minoxidil (2% / 5%)
*Applied directly to the scalp
*Converted in the skin to its active form (minoxidil sulfate)
*Absorbed through the scalp—efficacy depends on scalp condition + absorption
*Minimal systemic exposure
Low-Dose Oral Minoxidil (LDOM)
*Taken internally (prescription only, off-label for hair loss)
*Circulates systemically → affects the entire body
*Does not rely on scalp enzyme conversion
EFFICACY (WHAT THE DATA SHOWS)
~40–60% of users see visible improvement with consistent topical use
Oral minoxidil often shows higher response rates, especially in those who don’t respond to topical
Works best for:
*Androgenic alopecia (pattern thinning)
Early-to-moderate stages
👉 Response varies based on genetics, consistency, and underlying cause
