Minoxidil is the most accessible hair growth treatment on the planet. No prescription required for topical, available at any pharmacy, and clinically proven to work. Here's everything you need to know.
Originally a blood pressure medication, minoxidil's hair growth effects were discovered as a "side effect." Now it's one of only two FDA-approved treatments for hair loss.
As a vasodilator, minoxidil widens blood vessels in the scalp, increasing blood flow to hair follicles and delivering more nutrients and oxygen.
Minoxidil prolongs the anagen (growth) phase of the hair cycle, allowing hairs to grow longer and thicker before entering the resting phase.
Through mechanisms still being studied, minoxidil appears to directly stimulate dormant follicles, pushing them into active growth mode.
Unlike finasteride, minoxidil doesn't address the hormonal cause of hair loss. For best results, many people combine minoxidil with a DHT blocker. Learn about finasteride →
The most common question we get. Here's the honest breakdown.
Bottom line: Both work equally well. Choose foam if you have a sensitive scalp or want convenience. Choose liquid if you want to save money.

More convenient: One daily pill vs twice-daily topical application
More effective: Studies show superior results vs topical in many patients
Requires monitoring: Possible effects on blood pressure, potential for body hair growth

Started minoxidil and now shedding more? This is actually a good sign. Here's why — and why you shouldn't quit.
When you start minoxidil, it pushes resting hair follicles into the active growth phase. The old, thin hairs that were "hanging on" get pushed out to make room for newer, healthier growth.
This typically happens: Weeks 2-8 after starting treatment.
How long it lasts: Usually 3-6 weeks.
What the research shows: Higher initial shedding correlates with better long-term results.
The worst thing you can do is stop treatment during the shed — you've pushed out the old hairs but haven't given the new ones time to grow in.
Minoxidil is the easiest entry point into hair treatment. No prescription needed, available anywhere, and proven to work. Give it 3-6 months and see what happens.
