Dutasteride

A daily 0.5mg capsule that blocks both type I and type II 5-alpha reductase — the enzymes that turn testosterone into DHT, the hormone shrinking your hair follicles. In Olsen et al. (2006), dutasteride cut scalp DHT by ~90% vs ~70% for finasteride at 24 weeks.

How It Works

1

Answer health questions (about 3 minutes).

We ask about your hair loss history, medications, and anything that would rule dutasteride out.

2

A U.S.-licensed physician reviews your file.

If dutasteride is appropriate, they write the prescription. If it isn't, they'll tell you why and suggest alternatives.

3

Your prescription ships from a licensed U.S.

pharmacy in discreet packaging. One 0.5mg capsule daily. Your care team checks in and can adjust the protocol.

Why Patients Choose

Cuts scalp DHT by ~90% at 24 weeks (Olsen et al., 2006), vs ~70% for finasteride at the same timepoint

Increased hair count at the vertex vs finasteride and placebo at 24 weeks in the same Phase III trial (men aged 21–45 with male pattern hair loss)

One capsule daily

no injections, no topical mess, no daily routine to forget

Real prescription from a U.S.-licensed physician, dispensed by a licensed U.S.

pharmacy. Not a research chemical, not gray market.

Clinical Evidence

Clinical Trial

Findings apply to men in that age range with male pattern hair loss. Results in women, older men, or other forms of hair loss are not established and dutasteride is not FDA-approved for hair loss in t

How

Hair loss in men is driven by DHT — a hormone made when 5-alpha reductase converts testosterone. There are two versions of that enzyme

type I and type II. Finasteride blocks mostly type II. Dutasteride blocks both. Less DHT reaching the follicle means less shrinking, less shedding, and a longer growth phase for hairs that are still alive.

Frequently Asked Questions

Correct — in the U.S. it's FDA-approved for BPH and prescribed off-label for hair loss. Off-label prescribing is legal and routine when the evidence supports it; the Olsen 2006 Phase III data is the reason physicians use it here.

They're real and you should know the numbers. In the Olsen trial, decreased libido and erectile dysfunction each occurred in a single-digit percentage of men on dutasteride, similar in range to finasteride. Most cases resolve after stopping. If you experience them, tell your physician — dose can be adjusted or treatment stopped.

Often yes, in the first 2–3 months, as dormant follicles reset into a new growth cycle. It's expected, not a sign the drug is failing.

Dutasteride blocks both enzymes that make DHT, not just one — that's the ~90% vs ~70% number. It's also longer-acting in the body, which matters if you ever stop.

No. Women, especially those who are or may become pregnant, must not handle the capsules. Dutasteride can cause birth defects in male fetuses.

It blocks both type I and type II 5-alpha reductase, the enzymes that convert testosterone into DHT. Less DHT at the follicle = less miniaturization. In the Phase III trial, daily 0.5mg cut scalp DHT by about 90% at 24 weeks. When will I see results? Most men notice less shedding by months 2–3 and visible regrowth by months 4–6. Hair cycles are slow — judge results at 12 months, not 12 weeks. Stop the medication and the DHT comes back, and so does the loss. What are the real side effects? The most reported ones are decreased libido, erectile dysfunction, and ejaculation issues. In the Olsen trial these were in the single-digit percent range and similar to finasteride. Most cases resolve after stopping. A small number of men report persistent symptoms. Your physician will monitor and adjust. Do I need bloodwork? We recommend a baseline PSA before starting if you're over 40, because dutasteride lowers PSA and your doctor needs the baseline number to interpret future prostate screenings correctly. Your physician will tell you what's right for your situation. Can I take dutasteride with minoxidil? Yes — they work on different parts of the problem (DHT vs follicle blood flow and growth signaling) and are commonly stacked. Your physician can build that protocol with you. Is this FDA-approved for hair loss? In the U.S., dutasteride is FDA-approved for BPH and prescribed off-label for male pattern hair loss. It is FDA-approved for hair loss in South Korea and Japan. What if I want to stop? Stop anytime. Cancel in the dashboard. DHT levels return to baseline over several weeks; the hair benefit reverses over the following months.

6 months on Dutasteride and I can definitely see new growth coming in. The initial shedding was scary but the ArgoMD team prepared me for it. Worth the patience.

My hairline had been receding for years. After starting Dutasteride, the recession has stopped and I'm seeing baby hairs filling in. Very pleased.

The combination protocol my ArgoMD physician recommended including Dutasteride has made a noticeable difference. My barber even commented on it.
