Licensed US physician review

12,000+ patients treated

Available in all 50 states

Ongoing follow-up

Step 1

2-minute questionnaire

Tell us about your pattern of hair loss, how long it has been going on, any prior treatments, and your cardiovascular history. We ask the questions a dermatologist would.

Step 2

Physician review

A licensed physician confirms low-dose oral minoxidil is appropriate, screens for cardiovascular contraindications (low blood pressure, tachycardia, fluid retention), and writes your prescription. Usually within 1 business day.

Step 3

Prescription sent to your pharmacy

Your physician routes the prescription to the pharmacy of your choice. Pick it up, or have your pharmacy deliver if they offer it. Generic oral minoxidil is on essentially every formulary, but it is prescribed off-label so insurance usually doesn't apply.

Step 4

Follow-up at 3, 6, and 12 months

Hair-loss timelines are long. Most patients see shedding slow in 2 to 3 months and visible regrowth around 4 to 6 months. We check in along the way and your physician adjusts the dose if needed.

Why pay a membership fee? Minoxidil works only if you take it every day for months. Membership covers physician review, refills, and the follow-up that catches side effects (palpitations, edema, unwanted body hair) early and keeps you on plan. Because oral minoxidil is prescribed off-label, most insurance does not cover it, but generic cash prices are typically $10 to $25 per month. You pick up the prescription at your pharmacy and pay them directly.

Will my insurance cover oral minoxidil?

Oral minoxidil at low doses is prescribed off-label for hair loss, so most insurance plans will not cover it for this indication. Generic minoxidil tablets are inexpensive at the pharmacy — typically $10 to $25 per month with a discount card. We send the prescription to whichever pharmacy you'd like; you handle pickup and payment with them directly.

Week 1Day 1–5
Physician evaluation and prescription
A licensed physician reviews your history, screens for low blood pressure, tachycardia, fluid retention, or recent cardiac events, and writes your starting prescription. Most adults start at 2.5mg daily; women and patients sensitive to vasodilators sometimes start at 1.25mg. Patients under 21 are not prescribed through Instalab.
Week 1–4
Pickup and first doses
Pick up your minoxidil from the pharmacy you chose. Take it once daily, with or without food, at the same time each day. Some patients feel lightheaded or notice mild ankle swelling early on — message us if these are bothersome.
Month 2–6
Shedding slows; first signs of regrowth
A paradoxical shed in the first 4 to 8 weeks is normal as miniaturized hairs cycle out. Most patients see this resolve by month 3 and visible regrowth or stabilization by month 4 to 6.
Month 12+
Full effect and ongoing care
Visible regrowth typically peaks at 12 months and continues with sustained use. We keep your prescription active for as long as you choose to stay on it. Stopping reverses the gains over 6 to 12 months, so this is a long-term commitment.

About the medication

A daily oral pill, with a long arc to results.

One small tablet, once a day. Oral minoxidil works on the timeline of hair cycles, not weeks. Most patients see results in 4 to 6 months, with full effect by 12 months.

One pill, once a dayTake it at the same time each day, with or without food. Consistency matters more than timing.
Expect an early shedMany patients have a paradoxical shed in the first 4 to 8 weeks as miniaturized hairs cycle out. This is a sign the medication is working, not failing. It usually resolves by month 3.
Stopping reverses the gainsMinoxidil only works while you take it. Stopping leads to gradual regression over 6 to 12 months. Plan for long-term use.
Often combined with finasterideIn men, oral minoxidil and finasteride together produce more regrowth than either alone, because they hit different parts of the hair-loss pathway. Your physician can coordinate both.

Why minoxidil

Topical works. The pill works inside-out.

Minoxidil was originally a blood-pressure medication. Patients on the oral pill grew unexpected hair — that observation became Rogaine, the FDA-approved topical. Low-dose oral minoxidil (LDOM) brings the original mechanism back: a daily pill that vasodilates the scalp, prolongs each hair's growth (anagen) phase, and converts miniaturized vellus hairs back into terminal, pigmented hairs. It works on patterns and densities that topical alone can miss.

~75% see improvement in published seriesAcross published case series and meta-analyses of LDOM for androgenetic alopecia, roughly 75% of patients report visible improvement in hair density at 6 to 12 months. Response is best in the crown and vertex, with diffuse thinning also responding well.
Works on both men and womenUnlike finasteride, oral minoxidil is appropriate for women (provided they are not pregnant or could become pregnant). For women with female pattern hair loss, it is the most-prescribed off-label oral option in academic dermatology.
Skip the daily topical routineTopical minoxidil works, but twice-daily scalp application, dry residue, and irritation are why most patients quit. A daily pill is a fraction of the effort, and the systemic dose hits follicles topical applications can miss (frontal hairline, eyebrows, beard).

The published evidence

Low-dose oral minoxidil is prescribed off-label, so there is no single FDA-pivotal trial. The case for it comes from a growing body of dermatology literature: Sinclair and colleagues published the first large case series in 2017–2018; multiple studies since have replicated efficacy and safety at 0.625–5mg doses. A 2024 meta-analysis pooling published series found durable improvement in hair density with a manageable side-effect profile at low doses. It is the most-prescribed off-label oral hair-loss therapy in academic dermatology today.

Typical timeline to visible regrowth

Minoxidil is a prescription medicine. Important safety information applies. Oral minoxidil is prescribed off-label for hair loss. Most patients tolerate low doses well, but oral minoxidil has cardiovascular and fluid-retention effects that need physician oversight.
