Three mechanisms in one bottle, copper peptides, DHT inhibition, and liposomal delivery. Engineered in Switzerland to reduce shedding and support thicker, stronger hair.
Every type of hair loss is different and so is what works for it. Discover whether Serum N°1 targets the specific cause behind yours.
Find out whether our copper peptide formula could be a good match for your specific hair loss situation. Click on any topic below to see how it relates to Serum N°1.
Scarring alopecias (cicatricial) destroy the follicle itself. Once the follicle is gone, no topical can regrow hair from it. Serum N°1 supports living follicles, it cannot reactivate scarred ones. If you suspect scarring loss, see a dermatologist for diagnosis.
Acute stress can trigger telogen effluvium, a temporary shed that usually resolves on its own within 3–6 months. Serum N°1's copper peptides and follicle-support botanicals can shorten that recovery and reduce visible thinning during the cycle. Address the underlying stressor first; the serum supports the recovery.
Androgenetic alopecia (genetic male/female pattern loss) is driven by DHT sensitivity at the follicle. Serum N°1 attacks this on two fronts: 3.0% saw palmetto for topical 5α-reductase inhibition, and 3.0% GHK-Cu to extend the anagen growth phase. The liposomal carrier gets both into the follicle. This is exactly what the formula is engineered for.
The textbook case Serum N°1 was built for. Most users see reduced shedding by week 6–8 and visible density change by month 4. The 150-day guarantee covers a full follicular cycle so you can judge whether it works on your specific pattern.
Crown thinning is typically driven by the same DHT mechanism as MPHL. Apply directly to the crown; the calibrated dropper makes targeting easy. Most crown response shows in months 3–5 of consistent use.
Hairline recession follows the same DHT pathway. Apply to the hairline daily; the temple region is highly responsive to peptide stimulation in our 150-day cohort. Be patient, hairline density rebuilds slower than the crown.
Patchy spots are usually alopecia areata, an autoimmune condition, not androgenetic. It needs medical treatment (corticosteroids, JAK inhibitors). Serum N°1 is not formulated for this and won't address the underlying autoimmune trigger. See a dermatologist.
Diffuse thinning typically responds well to Serum N°1. The peptide stimulation, DHT inhibition, and follicle-support botanicals address the most common drivers (androgenetic overlap, telogen effluvium, post-illness shed) at once. Most users see fewer hairs in the drain by week 6–8 and visible density change at the part-line by month 4. If the underlying cause is purely nutritional or thyroid-related, address that in parallel.
Oral finasteride and dutasteride work systemically. Serum N°1 works topically and is fully complementary, you can layer them with no interaction. Many of our users do exactly this.
Minoxidil is a vasodilator, different mechanism than ours. The two layer well: apply Serum N°1 first, wait 20 minutes, then minoxidil. Or use Serum N°1 alone if minoxidil's irritation, initial shed, or twice-daily routine isn't working for you.
Serum N°1 is widely used post-transplant as part of the maintenance protocol, copper peptides support follicle survival in the graft window, and DHT inhibition protects the surrounding native hair from continued miniaturisation. Always follow your surgeon's specific timing instructions for topical application after the procedure.

I've wasted so much money on garbage over the years. I gave this one last shot and I'm honestly shocked, my hairline is thicker and my confidence is back.
BEFORE → AFTER
I was sceptical because most things marketed for women turn out to be repackaged shampoo. The peptide approach actually addresses thinning at the follicle. Five months in, I can see it in the part-line.
BEFORE → AFTER
I spent years feeling self-conscious, but now I can style my hair without worry. Documented results, substantiated, not staged.
BEFORE → AFTER
After trying countless treatments, I finally found something that works. My friends can't believe the difference, and the lab certificates put it beyond doubt.
BEFORE → AFTER
Two prescription protocols, three supplements, one ridiculous laser cap. This is the first thing that has actually moved the needle. The transparency made me trust it.

I'm a chemist by training. The Eurofins documentation was the reason I tried it. The result was the reason I stayed.

Post-pregnancy shedding hit me hard at month six. Started this at month three of the shedding cycle, within a few weeks the daily count dropped to normal. Crown is filling back in.
Twenty ingredients on the label. Three mechanisms in the bottle. Below: the actives. The supporting cast, humectants, preservatives, solvents, is fully disclosed on the homepage.
GHK-Cu is the most-studied peptide in dermatology. It signals collagen synthesis, supports angiogenesis around the follicle, and extends the anagen growth phase.
Serenoa serrulata berry extract, a natural 5α-reductase inhibitor. Targets the same enzyme as finasteride, applied topically, without systemic exposure.
A peptide that doesn't cross the stratum corneum is a peptide on the hairline. Our liposomal carrier encapsulates the actives in a phosphatidylcholine matrix, ~10× follicular penetration vs. aqueous solutions.
The protocol is short by design. Consistency outperforms intensity in every published trial we’ve read on topical scalp actives.
Apply to a dry, clean scalp. Best after evening shower or before bed. The scalp absorbs more when relaxed.
Eight drops, directly to the scalp. The calibrated dropper is precision-machined, eight drops is one milliliter, exactly.
Thirty seconds. Fingertips, not nails. Move in slow circles across the hairline, crown, and any thinning area.
We built the 150-day guarantee around the biology. Anyone promising results in 30 days is either marketing or lying, usually both.
Reduced itch and flake. Surface signal, barrier function recovering.
Most users report visibly fewer hairs in the shower drain. Not zero, but quieter.
Baby hairs return at the hairline and crown. Existing hair feels stronger, less brittle.
Full follicular cycle complete. The serum becomes a ritual, not an experiment.
Every batch is sent to Eurofins Scientific, an independent third-party lab, for HPLC verification of peptide content. If the label says 3.0%, the certificate confirms 3.0%.
We’re a topical cosmetic, not a pharmaceutical. The honest comparison:
Note: Serum N°1 is complementary, not a replacement. Many users layer it with finasteride or minoxidil with no interaction.
Three months in. Shedding noticeably down, I count fewer hairs on the pillow every morning. Hairline still receded but feels stronger, not brittle. The Eurofins certificate is what tipped me. Other brands send a label. This one sends paperwork.
Honestly didn't expect anything because nothing else worked. By week 5 I had visible baby hairs along the temples. Hair feels stronger when I run my hand through it. Wife noticed before I did.
I used minoxidil for 18 months and stopped because of irritation. Switched to this, no irritation, no shed. Up top and front, definite improvement. Will keep using.
"Every dude who's balding should try this."
"5 weeks in, baby hairs are back and my hair feels stronger."
"Steady hair growth, especially up top and in front. It's definitely working."
"First serum that didn't feel like marketing in a bottle."
"Hairline's holding and the crown is filling in. Quietly impressed."
Daniel, a Kiwi from New Zealand, ordered two peptide serums online in 2022. Both came from unregulated factories. He sent them to Marcus, a Swiss dermatologist, for testing. One had 5% of the labeled peptide content. The other was contaminated. Switzerland is the number one country in the world for pharmaceutical-grade peptide production — Bachem, just outside Basel, supplies the actives behind the world's leading dermatology programs. Eighteen months later, Serum N°1 came out of a contract pharmaceutical lab in Basel-Landschaft, formulated to that same Swiss standard.
