Why get hair loss treatment through My IV Doctors
Four ingredients, one step
Minoxidil, finasteride, ketoconazole and latanoprost are combined in a single scalp topical, so you apply one product instead of juggling several.
Clinician-checked first
A licensed clinician reviews your hair loss pattern and health before prescribing, and flags sudden or patchy loss that needs a different approach.
Made by a U.S. pharmacy
Your formula is compounded by a licensed U.S. pharmacy. Like all compounded medicines, it is not FDA-approved, and your clinician explains what that means.
Follow-up included
Your care team checks your progress and side effects over the months it takes to judge results, and answers questions as they come up.
How to get hair loss treatment online
- 1
Pick a time for your free visit
Choose phone or video. In about 5–10 minutes, a licensed clinician asks about your hair loss pattern, family history, past treatments and general health.
- 2
Send scalp photos
Clear photos of your hairline and crown help your clinician confirm the pattern and give you a baseline for later comparison.
- 3
Your prescription is sent
If your clinician decides treatment is appropriate, a licensed U.S. compounding pharmacy prepares the 4-in-1 topical and ships it with directions.
- 4
Apply daily and track progress
Use it as directed every day, and take photos in the same light at regular intervals. Your clinician reviews progress and side effects at follow-up.
Who this hair loss treatment is for
Men with pattern hair loss
Thinning at the crown or temples that has developed gradually is the classic pattern this formula targets.
One product instead of several
Combining ingredients means one routine instead of juggling separate bottles, which can make it easier to stay consistent.
Early or mild thinning
Treatment tends to work best at keeping the hair you have. Starting while thinning is mild generally gives you more to preserve.
Pregnant or could become pregnant
Finasteride can harm a male fetus. Women who are pregnant or could become pregnant should not use this formula or touch treated skin. Your clinician can discuss other options for women.
Sudden or patchy hair loss
Rapid shedding, round bald patches or scalp pain can point to other causes, such as thyroid problems, iron deficiency or alopecia areata, that need a different workup.

What is the 4-in-1 hair loss treatment?
The most common kind of hair loss is pattern hair loss, also called androgenetic alopecia. In men it usually shows as a receding hairline or thinning crown, and in women as a widening part or overall thinning. It is driven by genetics and by a hormone called DHT, which gradually shrinks sensitive hair follicles so they produce thinner, shorter hairs.
Two medicines have the strongest track record. Finasteride lowers DHT, and minoxidil keeps follicles in their growth phase longer. Both are FDA-approved for hair loss in their standard forms, finasteride as an oral tablet for men and minoxidil as a topical solution or foam.
Our 4-in-1 formula puts finasteride and minoxidil together in a topical with two supporting ingredients, ketoconazole and latanoprost. It is prepared by a licensed U.S. compounding pharmacy and, like all compounded medicines, is not FDA-approved. No topical finasteride product is FDA-approved, and the FDA has asked prescribers to explain its possible side effects clearly.
4-in-1 hair loss treatment ingredients
Each ingredient has a different job. The two main actives have the strongest evidence. The other two are added for supporting effects, with less research behind their use for hair.
- Minoxidil: extends the hair growth phase and can thicken existing hairs; topical minoxidil is FDA-approved for hair loss.
- Finasteride: blocks the enzyme that makes DHT, the hormone behind follicle shrinkage; oral finasteride is FDA-approved for male pattern hair loss.
- Ketoconazole: an antifungal used in dandruff and seborrheic dermatitis shampoos; it is added for scalp health, and its role in hair loss is supported by limited evidence.
- Latanoprost: an FDA-approved glaucoma eye drop known to lengthen eyelashes; its use on the scalp is off-label and still being studied.
How long hair loss treatment takes to work
Hair grows slowly, so patience matters. MedlinePlus advises that topical minoxidil takes at least 4 months, and possibly up to a year, before effects appear, and that finasteride usually needs at least 3 months. Some people notice extra shedding in the first weeks, which often settles as follicles reset.
The benefits last only as long as you keep using treatment. When minoxidil is stopped, most new hair is typically lost within a few months, and hair regained with finasteride is generally lost within a year of stopping. Think of this as ongoing care rather than a short course.
Hair loss treatment side effects and safety
Applying finasteride to the scalp lowers but does not remove the chance of side effects. In 2025, the FDA reported adverse events with compounded topical finasteride, including erectile dysfunction, lower libido, anxiety, depression and suicidal thoughts, and most reports said symptoms continued after stopping.
- Stop and contact your clinician right away if you have new or worsening low mood or thoughts of self-harm.
- Sexual side effects, such as lower sex drive or erection problems, can occur and may persist after stopping.
- Pregnant women and women who could become pregnant should not handle the product or touch treated skin; wash your hands after applying.
- Scalp itching, dryness, flaking or irritation are common with minoxidil and ketoconazole.
- Call your doctor for chest pain, a racing heartbeat, lightheadedness, sudden weight gain or swelling, which are rare minoxidil warnings.
- Keep latanoprost-containing product away from your eyes; in eye-drop form it can darken eye color and lashes.

Hair loss treatment FAQs
Still deciding? The first consultation is free and takes about 5–10 minutes.
Book a free consultationWhat's in the 4-in-1 hair loss formula?
Minoxidil, finasteride, ketoconazole and latanoprost, combined in one topical. It is compounded by a licensed U.S. pharmacy and is not FDA-approved.
How much does hair loss treatment cost?
The 4-in-1 formula is $199. Your first consultation is free and you do not need insurance. Your clinician confirms the cost and supply before you commit.
How long does hair loss treatment take to work?
Most people need at least 4 months of daily use, and sometimes up to a year, to judge results. Photos taken in the same light every few months make changes easier to see.
Is topical finasteride safer than oral finasteride?
Applying it to the scalp is intended to reduce exposure to the rest of the body, but side effects can still happen. The FDA has received reports of sexual and mood side effects with compounded topical finasteride, some lasting after people stopped.
Can women use the 4-in-1 hair loss formula?
Not if they're pregnant or could become pregnant, because finasteride can harm a male fetus. Your clinician can discuss other options suited to female pattern hair loss.
What happens if you stop hair loss treatment?
Hair loss usually resumes. Most new hair from minoxidil is lost within a few months, and gains from finasteride generally fade within a year.
Is shedding normal when you start hair loss treatment?
Some people notice extra shedding in the early weeks as follicles move into a new growth cycle. It often settles, but tell your clinician if it worries you.
Why are ketoconazole and latanoprost in the formula?
Ketoconazole is an antifungal that helps with dandruff and scalp inflammation, and latanoprost is a glaucoma drug that lengthens eyelashes. Both are added for supporting effects, with less evidence for hair than minoxidil or finasteride.
Is topical finasteride safe around partners and kids?
Let the product dry fully and wash your hands after applying. Women who are or could become pregnant should avoid touching treated skin, and children should not come into contact with it.
Can hair loss treatment help a receding hairline?
It can help slow loss, but crown thinning often responds better than the hairline. Your clinician can set realistic expectations based on your pattern.
Do I need blood tests for hair loss treatment?
Usually not for typical pattern hair loss. If your loss is sudden, patchy or comes with other symptoms, your clinician may order labs to look for thyroid or iron problems.
Can I use hair loss treatment while on testosterone?
Testosterone therapy can speed up pattern hair loss in some men. Your clinician will consider your full treatment plan before prescribing.
What if hair loss treatment doesn't work for me?
Your clinician can review whether the diagnosis is right and discuss other approaches. Some people do better with different strengths or other evidence-based treatments.
