Minoxidil hair loss pills

In November 2024, an important publication was published in JAMA Dermatology: 43 hair loss experts from 12 countries came to an international consensus on the use of low-dose oral minoxidil against hair loss.

They formulated 76 best-practice recommendations regarding dosage, safety and monitoring of oral minoxidil. There was strong agreement that oral minoxidil in low doses may be effective and safe for various forms of hair loss, including hereditary baldness, alopecia areata and telogen effluvium.

This means that oral minoxidil, although officially still off-label, is now seen worldwide as a serious and increasingly accepted treatment for hair loss. For men, the experts often recommend a starting dose of 2.5 mg/day, for women 1.25 mg/day.

At 3CO, you can easily go through an online consultation to get minoxidil pills with a doctor's prescription. Your consultation is always personally reviewed by a BIG-registered doctor to determine if it is a safe option for you. One pill a day can reduce hair loss and make your hair grow longer and thicker.

What is minoxidil in pill form?

Minoxidil was approved by the FDA as a high blood pressure medication in 1979. An unexpected side effect was hair growth, which led to it being developed as a treatment for hair loss. The topical variant is freely available, while minoxidil pills are prescribed off-label by doctors for hair restoration.

The recommended dose for hair loss is 1.25 mg per day for women and 2.5 mg per day for men, significantly lower than the dose for blood pressure treatment (10-40 mg per day).

What does off-label mean?

Off-label means that a medication is prescribed for a purpose other than that for which it was officially approved. Oral minoxidil is not officially approved for hair loss, but more and more studies are showing that it is effective and safe.

How does minoxidil in pill form work against hair loss?

Minoxidil stimulates hair growth by improving blood flow to hair follicles. This is done via the enzyme sulfotransferase, which prolongs the growth phase of the hair and reduces hair loss. As a result, the hair grows longer and thicker.

Minoxidil pills vs. Topical minoxidil

Topical minoxidil

• Apply to scalp.
• Use twice a day.
• Works locally on hair follicles.
• Freely available.

Oral Minoxidil (Minoxidil Pills)

• In pill form, taken once a day.
• Works via the bloodstream, stimulates general hair growth.
• May cause hair growth on other parts of the body (e.g. eyebrows).
• Only available with a doctor's prescription.

Why choose minoxidil pills?

Many users choose oral minoxidil because:

• It's easier than applying lotion twice a day.
• It does not cause irritation on the skin, as topical minoxidil sometimes does.
• It has a wider effect and may be more effective in some forms of hair loss.

What are the possible side effects of minoxidil pills?

Side effects occur mainly at higher doses. At low doses for hair loss, they are rare. Possible side effects include:

• Hypertrichosis (extra hair growth on face/arms/legs)
• Edema/fluid retention (ankles, feet, sometimes face)
• Heart palpitations/increased heart rate (tachycardia)
• Low blood pressure/dizziness (orthostatic hypotension)
• Headaches
• Dizziness/light-headedness
• Weight gain (due to moisture)
• Shedding (temporary more hair loss in the initial phase)
• Fatigue
• Gastrointestinal complaints (nausea, abdominal pain, rare)
• Skin reactions (allergy, rash — rare)
• Very rare: cardiovascular complications in people with underlying heart disease

Note: Minoxidil should not be used during pregnancy or in breast-feeding women.

Minoxidil pills and finasteride: an effective combination

Minoxidil is often combined with finasteride, another proven hair loss remedy. Studies show that this combination provides better results than used separately. Please note that the use of Finasteride is currently only allowed for men.

At 3CO, you can go through an online consultation, where a doctor assesses whether minoxidil pills and/or finasteride are a suitable treatment for you. When approved, you can order them directly as a subscription, so you never have to run out of medication again.
