Why you are losing your hair: DHT, the androgen receptor, and what actually stops it
Not stress, not your shampoo, not the hard water - in the overwhelming majority of men, one androgen acting on follicles that...

HOW IT WORKS
What DHT does.
Most hair loss is caused by DHT — a hormone that slowly shrinks your follicles until they stop growing hair. Our formulas stop that process right at the scalp.
- 01
Block DHT
The active binds to the receptor on your follicle so DHT can't attach and keep shrinking your hair.
- 02
Protect the follicle
Applied to the scalp only. It works where the problem is — without moving through the rest of your body like a pill does.
- 03
Regrow
With DHT blocked, weakened follicles recover and grow thicker hair again. Most people see change in three to six months.
Why topical, not a pill
Oral DHT blockers work through your entire body, which is where their side effects come from. A topical antiandrogen concentrates the effect on your scalp and keeps it there — the potency of a real antiandrogen, applied only where you need it. That is the whole point of the RU-58841 approach.

small shed at first but stopped after a few weeks

Took about two weeks to turn up and the tracking sat frozen for days, was getting annoyed ngl. product itself is good but the wait sucked
Verified buyer

started this after two years of fin then minox. fin held my hair but messed with me too much so i stopped. minox was great for like 8 months then all the hair i saved started falling out at once, was grim. this was kind of a last try. first couple months nothing, then around month 3 the shed stopped and by month 6 there was actual regrowth on the crown. not 18 year old hair but way better. one less thing to stress about

THE THREE OPTIONS
RU58841, finasteride, minoxidil — side by side.
Three compounds, three different jobs. Where each one acts, what it costs you, and the rows where we come off worse.
| Feature | THIS PRODUCTFolliva RU58841Topical antiandrogen, 5% | Oral finasterideSystemic DHT blocker | Topical minoxidilTopical growth stimulant |
|---|---|---|---|
| Mechanism | |||
| How it works | Blocks DHT at the receptor, in the scalp | Lowers DHT body-wide, at the source | Pushes follicles into growth. It does nothing to DHT. |
| Where it acts | Scalp, by design | Whole body. Scalp, prostate, brain, blood. | Scalp. Some absorption. |
| Side effects | |||
| No systemic or sexual side effects | YesIt breaks down in the scalp before it reaches your bloodstream. There is nothing left to act on the rest of you. | NoLower libido, erectile problems and reduced ejaculate. Most men recover after stopping. Some report that they never did. | YesNot a hormonal drug. Rare heart-rate effects at high doses. |
| No effect on energy, mood or sleep | YesIt never reaches the systems that set them. | NoLow energy, daytime drowsiness, brain fog, low mood and breast tenderness are all reported. You are dosing your whole body, so your whole body can answer. | YesNot hormonal. It does not touch them. |
| No scalp irritation | PartlyThe alcohol carrier can dry or sting. That is the vehicle, not the compound. | YesIt never touches your scalp. | NoItching and flaking are common. Mostly the propylene glycol. |
| What it does | |||
| Stops the loss itself | YesIt blocks the hormone that shrinks the follicle, which is what drives the loss. | YesThe best proven of the three. The cost is that it works everywhere in your body. | NoIt grows hair while the DHT keeps working. Growth into a headwind. |
| Stimulates new growth directly | PartlyNot by forcing it. Take the DHT off a miniaturised follicle and it can come back on its own — natural regrowth, not pushed. | PartlyThe same route, and the best documented of the three: regrowth in most men once the suppression is gone. | YesDirectly, and it is the one thing it is for. That is why people run it alongside a blocker. |
| When the loss slows | Months 1–2 | Months 1–3 | It does not stop the loss |
| Access | |||
| Available without a prescription | YesNothing to prescribe: there is no approved use anywhere. Shipped direct across the EU. | NoPrescription only. A doctor has to agree. | YesOver the counter. |
A comparison of mechanisms, not medical advice. Finasteride and minoxidil are approved medicines with decades of randomised trials behind them, and finasteride has the longest evidence base of the three. RU58841 is a research compound: no completed human trial exists for it, and it is not an approved hair-loss medicine anywhere. What is known about it comes from its mechanism and from animal work, not from trials in people. The timings above are typical, not promised. Speak to a doctor before you start or stop anything.
FAQ
Questions, answered.
When will I see results?
Six months is the earliest point at which a fair judgement is possible, and it has to be made against photographs, not memory. Anything before that is mood. The month-by-month timeline is here.
Are there side effects?
What gets reported: scalp irritation, dryness and flaking, redness where it is applied. Most of that tracks the carrier rather than the compound. What nobody can give you is a real safety profile — the long-term human trials were never run. Patch test before it goes near your head, and stop if you react. More here.
How do I know it's genuine?
We blend it ourselves in the EU — it is not rebottled, not dropshipped, and it does not sit in a warehouse. Every bottle carries its batch number, blend date and expiry, so you always know how old the thing in your hand is. RU-58841 degrades with time; a fresh batch matters more than most people realise.
Shipping and returns?
Shipped from the EU, usually 3–5 days. Unopened bottles can be returned within 14 days.
