Lower sex drive and erection problems are on the medication labels. Your follicles have a different problem, and it can be treated without touching your hormones. Here is what is happening on your scalp, and the new way to send the growth signal back.
A thinning patch is follicles growing thinner hair. They are still there and they can still respond.
It lowers a hormone in your whole body. That is where the side effects on the label come from.
Growth signals your body already makes, delivered to your scalp intact. An independent 12-week study measured it.
Reason 1 Your follicles
Look at a thinning patch and you are not looking at empty skin. The follicles are still there and still working. Each cycle they grow a hair a little thinner and a little shorter than the last, until the scalp shows through.
That is why it sneaks up on you. Day to day nothing changes. Month to month, a photo from above says otherwise.
Reason 2 The signal
Two proteins your body makes, FGF·2 and FGF·7, tell a follicle to start a growth phase and to keep going. With age, and faster with male-pattern hair loss, that signal gets weaker at the temples and crown first.
The follicle does not stop. It downgrades. Thinner hair, shorter cycles, more scalp. Give it the signal back and it has what it needs to grow a proper hair again.
Reason 3 The medication
Finasteride and dutasteride do not send a growth signal. They block the enzyme that turns testosterone into DHT, and they block it everywhere the enzyme is, not only at your hairline.
That is the mechanism. It is also the reason the side effects exist. You cannot have one without the other.
Reason 4 The label
You do not need a forum to know the risks. Both drug labels list lower sex drive, erection problems and ejaculation problems, and reports that continued after stopping.
Not every man gets them. Enough do that many men never start. Here is what each route changes in you.
| What it changes | A growth-signal serum | Hair-loss medication |
|---|---|---|
| Your hormones | Nothing. It touches no hormone. | Lowers DHT in your blood and scalp |
| Where it acts | On your scalp, at the follicle | In your whole body |
| On the label | Possible scalp irritation | Lower sex drive, erection and ejaculation problems |
| What you do | One pump at night, for 12 weeks | A pill a day, for as long as you want the hair |
| How it was tested | Independent 12-week placebo-controlled study | Approved for male-pattern hair loss |
Reason 5 The problem
A growth signal is a protein. In water it unfolds and stops working. Heat speeds that up. Time finishes it.
That is why serums you may have tried listed impressive actives and did nothing at your follicle: the active was gone before it reached you. For the signal to work, it has to arrive in the same shape your body makes it.
Reason 6 The breakthrough
Core Biogenesis spent five years fusing FGF·2 and FGF·7 to an oleosome, a natural oil body from the camelina seed, during production. The protein never touches water. It ships cold and reaches your scalp in the shape that works.
That active is exclusive to one product, OF·27, a nightly scalp serum. It carries both signals, 100 and 500 ng/mL, printed on the label. No hormone in the bottle and nothing to swallow.
Each growth factor is bound to its oleosome carrier before it ever meets water.
The bottle travels and lives refrigerated, so the protein keeps its shape.
One pump on your scalp puts the signal where your follicles can use it.
Reason 7 The proof
Abich S.r.l., an independent laboratory in Italy, tested the active on 40 people for 84 days, half of them on a placebo, randomised and blinded. Density was measured with a phototrichogram, the scalp scan used in prescription hair trials.
The active group's hair density rose 33.5% from where it started. 90% of them improved on the clinical density score. On placebo, 35% did.
The study enrolled women. Your follicles use the same signals, and your own two photos will tell you what it did for you.
Share of participants whose clinical hair-density score improved by week 12.
Reason 8 Your routine
Massage one pump of the Follicular Serum into your scalp before bed and leave it on. Once or twice a week, the Scalp Reset Serum on a dry scalp for three to five minutes, then rinse, so the nightly pump reaches the follicle.
Take a photo of your crown or hairline when the box arrives, and the same photo at week 12. If you cannot see a difference, OF·27 refunds the product price.
Email your first scalp photo to contact@of27bioscience.com.
One pump every night, Scalp Reset once or twice a week, no breaks.
Send the matched photo with your order number. No visible difference, product price refunded.
One customer, in his own words
I followed the recommended routine of one pump each night before bed. The airless bottle makes the serum easy to dose, and the formula fits into my routine without affecting styling. My hairline looks fuller and the thinner areas look denser than when I started. The experience has been very positive.
This feels nothing like the treatments I've tried before. My hair looks fuller and thicker for the first time in years.
Two serums that work as a pair, and a short guide that tells you exactly what to do.
A rinse-off exfoliating treatment. It clears buildup and excess oil so the scalp is clean and calm before the nightly serum goes on.
One pump on the scalp before bed. Leave it on. One 50 mL bottle lasts 6 weeks, so the two bottles in the Advanced Protocol cover the full 12 weeks.
A short PDF, emailed the moment you order: how to use both serums, when to open the second bottle, and how to take your two photos for the guarantee.
One pump a night. +33.5% hair density in the 12-week study of the active.
Next batch ships mid-October and it's already:
Use the Advanced Protocol every night for 12 weeks. Take a photo of your parting when the box arrives and another at week 12. If you can't see a difference between the two, we refund you.
The duration measured in the study is 12 weeks, one pump nightly, and one 50 mL bottle covers six weeks. The Advanced Protocol covers the full 12 weeks, includes the Scalp Reset Serum and the written guide at no extra charge, and carries the money-back guarantee; the Standard Protocol covers the first six weeks with a single bottle and gives you a chance to try the product.
On the Advanced Protocol, the written guide arrives by email today; the serums ship together in one shipment with the next batch in mid-October, in order of reservation. The Standard Protocol is one bottle, shipped the same way. Nothing else ships at purchase.
OF·27 is a refrigerated protein formulation bottled to reservations in one small run, so nothing is warehoused. Your payment reserves an allocation at the pre-order price and fixes your place in the dispatch order. You can cancel for a full refund at any time before dispatch.
It prepares the scalp: a rinse-off exfoliating treatment that removes buildup and excess oil and rebalances the scalp, so the nightly serum is applied to a clean, prepared scalp. The measured result comes from the study of the active, applied nightly across 12 weeks. The Scalp Reset Serum is included with the Advanced Protocol.
In the study, the measurements were taken at week 12. Photograph your scalp before the first application and again at week 12, in the same light; that comparison is also what the guarantee is assessed on. We cannot predict an individual result.
Advanced Protocol orders carry the money-back guarantee. Email a baseline photograph to contact@of27bioscience.com within seven days of delivery, run the full 12 weeks as directed, and send a matched photograph at week 12. If we cannot see a visible difference between the two, we refund the product price; shipping, duties and taxes are not refunded. Claims open between the end of week 12 and the end of week 14; one claim per customer, on a first order placed directly on of27bioscience.com. Full conditions.
OF·27 is marketed as a cosmetic and is not intended to diagnose, treat, cure or prevent any disease. It is a topical built around two fibroblast growth factors, FGF·2 and FGF·7, carried in a plant-derived oleosome, and it is not a prescription product. If you already use a prescription treatment, speak to your prescriber before adding anything.
The study ran twelve weeks; we have no data on what happens after week 12, with or without continued use, and we will not guess. If you choose to continue, one bottle covers six weeks.
