Low Dose Oral Minoxidil

Researchers are studying how a decades-old blood pressure medicine may help prolong the hair growth cycle and support regrowth over time.

Low Dose Oral Minoxidil:
How does it work?

In the 1980s, dermatologists began studying a much smaller dose of Minoxidil for hair thinning instead.

Studies find it widens blood vessels around each follicle, which may help keep more follicles in their active growth phase.1,5

What Low Dose Oral Minoxidil may support

Even as hair follicles shrink with age or hormonal changes, many remain alive beneath the scalp. Low Dose Oral Minoxidil is being studied for its effect on the hair growth cycle itself, not just the scalp’s surface. 
Some follicles remain capable of producing hair, even when growth has slowed.
Research suggests Minoxidil may help some follicles produce thicker hairs and spend more time in active growth phase.1,5

How Low Dose Oral Minoxidil works

(mih-nok-sih-dill)

Think of it as opening a valve.

Once converted into its active form, Minoxidil widens the blood vessels around each hair follicle, so more blood, oxygen, and growth signals can reach follicles that have been pushed into a resting state.

Our research

Hair health deserves a place in longevity science

Hair follicles change as we age, just like the rest of our bodies. And while hair thinning is often treated as a cosmetic concern, the biology behind it deserves scientific attention.

That’s why we’re bringing published research and personalized care together, backed by our Stanford PhD-led Research Team and 16 in-house licensed clinicians with 199+ years of combined clinical experience.

Frequently asked questions

01 What is Low Dose Oral Minoxidil?

Low Dose Oral Minoxidil is an oral tablet, a low dose of minoxidil prescribed off-label to help support hair regrowth in people with thinning hair or androgenetic alopecia.

02 Is Low Dose Oral Minoxidil FDA-approved?

No, not for this use. Minoxidil is FDA-approved only for treating resistant high blood pressure. Using a much lower dose for hair regrowth is an off-label use, supported by a growing body of published clinical evidence.1,2,6

03 Is Low Dose Oral Minoxidil safe?

It is generally well tolerated at the doses used for hair regrowth, far below blood-pressure doses. The most common effect is hypertrichosis, extra hair growth on the face or body, which is cosmetic rather than dangerous.2

For full safety info, see the product page.

04 How is Low Dose Oral Minoxidil different from topical minoxidil?

They share the same active ingredient. Topical minoxidil is a solution or foam applied to the scalp. Low Dose Oral Minoxidil is a pill that works throughout the body rather than sitting on the scalp. Research suggests the two forms offer comparable effectiveness for regrowth.1

05 What happens if I stop taking Low Dose Oral Minoxidil?

Hair regrowth benefits are not permanent. If treatment is discontinued, hair loss typically resumes within a few months, so ongoing use is generally needed to maintain results.

06 Can I combine Low Dose Oral Minoxidil with topical minoxidil or finasteride?

Most people use one form of minoxidil rather than both. Finasteride works differently, on hormones rather than blood flow, so some care teams prescribe the two together. Ask your care team what makes sense for your goals before combining anything on your own.
