Once a day. Twenty seconds. Dries clear.
NAPE Peptide Hair Serum
For hair that's thinning while there's still fine hair in the area.
A once-a-day scalp serum built around Baicapil™ — a complex tested against a placebo on 61 people over six months — in a water-based formula with no alcohol and no propylene glycol. One dropper, worked in for twenty seconds. Nothing to wash out.
- Less of it left in the shower.The first thing most people look for. In the Baicapil study, hair loss measured −60.6% at three months against day one — on the studied lotion, at 3%.
- You'll feel it in the ponytail before you see it in the mirror.Hair that feels thicker between your fingers is usually the first change — the one you can't photograph yet.
- A part that photographs the way it used to.Judge it against a day-one photo, in the same light. Twelve weeks is the honest window, and the guarantee covers it.
- A scalp that isn't itching by six in the evening.Eucalyptus leaf extract for comfort, in a base with no alcohol to dry the skin out.
- Twenty seconds, once a day, on a dry scalp.One dropper, worked in with fingertips. It dries clear in about a minute — no crust, no grease, nothing to wash out before styling.
For external use only. Avoid contact with eyes. Patch test before first use. Discontinue if irritation occurs. Sunburn alert: this product contains an alpha hydroxy acid that may increase sensitivity to the sun. Not for use by athletes subject to anti-doping testing. Not recommended during pregnancy or breastfeeding, or with a history of hormone-sensitive cancer - ask your doctor.
What people tend to notice first — and when
Hair runs on its own timetable: months, not weeks. This is the order things usually show up in, so you know what to look for and when to look. Take a photo on day one, in the light where you first noticed it.
Weeks 1–2
Scalp comfort, and a serum you don't notice
Less tightness and itch by the evening. Hair that isn't wet, greasy or crusted after applying. This is the part that decides whether you're still using it in week six.
Weeks 3–6
Texture — in the ponytail, not the mirror
Hair that feels a little thicker between your fingers, or heavier in the hand. It's usually the first change, and it's the one you can't photograph yet.
Weeks 6–10
The shower, the pillow, the brush
Less of it left behind. It's what the Baicapil study measured at three months, and it's what most people are quietly checking for every morning.
Week 12
The photo
The part or hairline, judged against your day-one photo in the same light. Nothing else is a fair comparison — not memory, not the mirror on a good day.
One full dropper. Not a third of one.
Both our bottle and the cheap ones hold 30 ml. The difference is what you are told to do with it. A full dropper parted across four or five sections of scalp uses about a millilitre a day, which is why a bottle is a month.
A 30 ml bottle sold as a three-month supply is the same glass with a third of the dose. That is where the low price comes from, and it is why so many people conclude that peptide serums do not work.
1 ml a day
A full dropper, once daily. 30 ml lasts thirty days, which is what a month of use actually costs.0.33 ml a day
A third of a dropper across an entire scalp. The bottle lasts longer because far less of it reaches you.Twenty seconds, once a day. Nothing to wash out.
On a dry or towel-dried scalp — on the skin, not the lengths. Morning or evening, whichever you'll actually keep.
1
Photograph it first
Before the first application, take a photo of the area in the light where you first noticed it. In ninety days it's the only comparison that will tell you anything.
2
Part and apply
Draw one dropper. Part the hair over the area you care about and lay the serum onto the scalp in a few lines — the skin, not the lengths.
3
Twenty seconds, then leave it
Work it in with your fingertips for about twenty seconds. Don't rinse. It dries clear in about a minute and it's fine on colour-treated hair.
The part nobody tells you
The reason most topicals fail isn't the formula, it's week six. Nothing visible has changed, the bottle is two-thirds gone, and it quietly stops getting used. That is the single biggest predictor of whether this works for you.
Which is why it's built to be easy to keep — once a day, dries clear, nothing to wash out — and why the guarantee runs ninety days, not thirty.
Tested against a placebo. Not a questionnaire.
NAPE contains Baicapil™ — a complex of Scutellaria baicalensis root, soy germ and wheat germ. Its maker, Provital, tested it on 61 volunteers, men and women aged 18–60, for six months: half on a 3% Baicapil lotion, half on a placebo lotion.
61 people, six months
Men and women, 18 to 60. Half used a lotion with 3% Baicapil, half used a placebo lotion — the comparison most products in this category never run.
Hair loss: −60.6% at three months
Measured against day one, in the Baicapil group. In plain terms: less of it left behind.
Hair density: +59.3% at three months
Measured against day one, in the Baicapil group. In plain terms: a part that photographs closer to the way it used to.
What it didn't measure
It didn't test NAPE as a finished product, and it's the supplier's own study. The results belong to the studied complex at its studied level. We'd rather you know both things than neither.
Figures are from Provital’s study of Baicapil™ at 3%, on the studied lotion. NAPE is a cosmetic product and is not intended to treat, prevent or cure any condition.
What's in the bottle, and what each part is there for
Four things, in the order you'll notice them.
Baicapil™ — the studied complex
Scutellaria baicalensis root, soy germ and wheat germ. The reason there's a placebo-controlled study behind this product at all: 61 people, six months, hair loss and density measured against day one.
Scutellaria baicalensis root extract, Glycine soja germ extract, Triticum vulgare germ extractFive peptides
The part of the formula the name comes from. Water-soluble, which is why the base can stay free of alcohol and still carry them.
sh-Polypeptide-1 / -9 / -11, sh-Oligopeptide-2 / -10Eucalyptus leaf extract
For scalp comfort — the ‘isn't itching by six in the evening’ part. Studied on people for scalp condition and shine, which is exactly what we use it for.
Eucalyptus globulus leaf extractThe base
Water, glycerin, lecithin, propanediol. No alcohol, no propylene glycol, no fragrance. It dries clear in about a minute and it doesn't flake — the difference between a serum you use for ninety days and one you abandon in week two.
Water, Glycerin, Lecithin, Propanediol
Use the whole bottle. Use all three.
If your hair hasn't changed in ninety days, we refund what you paid. One email, no restocking fee, no hoops.
Ninety days isn't a round number chosen because it sounds generous. It's the shortest honest window in which anything topical can be judged on hair — and it's the window the Baicapil study itself reported at.
- Ninety days, not thirty. Long enough to actually judge it.
- One email, no questions. No restocking fee, no forms, nothing to post back.
- Nothing to cancel. Every pack is a one-time purchase. There is no subscription to unwind.
The full terms are in our Refund Policy. In short: claims are made by email, and the guarantee covers each customer once. Faulty, damaged or incorrect orders are handled separately and are not counted as a guarantee claim.

Why it's built the way it is
Most of what decides whether a serum does anything is whether you're still using it in week six. Every choice in the bottle is made with that in mind.
Step 1 · Once Once a day, not twice
One application, morning or evening. A twice-daily routine is the one most people quietly drop by the second week.
Step 2 · Clear Dries clear in about a minute
No alcohol, no propylene glycol. It doesn't leave hair wet, greasy or crusted, so there's nothing to wash out before you style.
Step 3 · Comfort Kind to the scalp it sits on
Eucalyptus leaf extract in a water-and-glycerin base. A scalp that's tight and itching by the evening is a scalp you'll stop treating.
Step 4 · Studied Built around a studied ingredient
Baicapil™ was tested on 61 people against a placebo for six months. It's the reason this page can show you numbers instead of adjectives.
What's in it, one at a time
Baicapil™
Scutellaria baicalensis root · soy germ · wheat germ
- 61 people: Men and women, 18–60, six months, half on a placebo lotion
- Hair loss: −60.6% at three months against day one, in the Baicapil group
- Hair density: +59.3% at three months against day one, in the Baicapil group
It's the reason this page can show you a study instead of a testimonial. Supplier study, at 3%. The results belong to the studied complex, not to NAPE.
Five peptides
sh-Polypeptide-1, -9, -11 · sh-Oligopeptide-2, -10
- Named on the label: All five, in order, on the bottle
- Water-soluble: Why the base can stay free of alcohol
- In the name: The part of the formula NAPE is built around
We name them and we don't make promises about them. What we can say is that they sit in a base built to keep you using it.
Eucalyptus leaf extract
Eucalyptus globulus
- Scalp comfort: For a scalp that isn't tight or itching by the evening
- Studied on people: For scalp condition and hair shine
- Every day: Comfort is what keeps a daily serum daily
A serum you use for ninety days has to feel like nothing. This is the ingredient that does that job.
Arginine
Amino acid
- In the base: An amino acid hair is partly built from
- Conditioning: Helps hair feel smoother through the lengths
- Nothing hidden: Listed in full on the label
It's here for how hair feels, and that's how we describe it.
The base
Water · glycerin · lecithin · propanediol
- Dries clear: In about a minute, no residue
- No alcohol: Nothing to dry the scalp out
- No propylene glycol, no fragrance: Fewer reasons to react
The base is most of the bottle, and it's most of the reason people keep using it.
Research described here was conducted on individual ingredients as studied, not on the finished NAPE formula. NAPE is a cosmetic product and is not intended to treat, prevent or cure any condition.
What's not in it
A serum sits on your scalp every day for months. What's been left out of it matters as much as what went in.
Formulation attributes confirmed by the manufacturer of the formula.

The questions that actually stop people
Is this a subscription?
No. Every pack is a one-time purchase — you are charged once, nothing renews, and there is nothing to cancel. When you run out, you decide whether to buy again.
How long until I notice something?
Scalp comfort is usually first, within the first couple of weeks. Texture in the ponytail tends to come next, then less left in the shower somewhere around weeks six to ten. The part or hairline is a twelve-week photo, not a mirror check. Months, not weeks.
What exactly does the 90-day guarantee cover?
The full amount you paid. Use all three bottles. If your hair hasn't changed, email us within ninety days and we refund you — no restocking fee, no forms.
Why three bottles?
Because one is a month, and a month can't tell you anything about hair. Ninety days is the shortest window you can judge it in — it's the window the guarantee covers, and the one the Baicapil study reported at.
Do I need to keep using it?
Yes. That's true of every topical in this category. It's a daily product, which is why it's built to be easy to keep: once a day, twenty seconds, dries clear.
Is this minoxidil?
No, and it doesn't contain it. It's a cosmetic scalp serum, applied once a day, with no alcohol and no propylene glycol in the base — so it dries clear rather than leaving hair wet.
Is it for women or men?
Both. Most of the people we built it for are women who noticed it in the part or the ponytail first; men more often notice the crown or the corners. The routine and the guarantee are the same.
Will it cause the shedding phase people talk about?
That effect is most associated with starting certain drug topicals. It isn't something we'd expect from a cosmetic serum, and it isn't something the Baicapil study reported. If you notice anything unusual in the first weeks, stop and email us.
Is it safe on colour-treated or chemically treated hair?
Yes. It goes onto the scalp rather than the lengths, dries clear and does not interfere with colour or chemical treatments.
Who should not use this?
It contains an alpha hydroxy acid, so use sun protection on any exposed scalp. If you are pregnant, breastfeeding, have a history of hormone-sensitive cancer, or are subject to anti-doping testing, ask your doctor first. If your scalp is already smooth and shiny in an area, see the next question.
Will it do anything where my scalp is already smooth?
Probably not in those places — ours or anyone else's. It's made for hair that's thinning while there's still fine hair in the area. If there is, that's where to apply it.
Why is it more expensive than the serums I see on Instagram?
Dose. A 30 ml bottle sold as a three-month supply is the same glass with a third of the daily amount. Ours is one dropper a day, so a bottle is a month — and the price per month is what it costs to actually use it.
Where is it made?
Manufactured in the USA using globally sourced ingredients. The full ingredient list is printed on the bottle, in order, and on this page.
Ninety days, and you'll know
Three bottles is the course. Take the photo today, one dropper every day, and judge it in three months against that photo — not against memory.
What this is not. It is not a drug and it is not a transplant. Where a scalp has gone smooth there's nothing for a topical to do — ours or anyone else's. It's made for hair that's thinning while there's still fine hair in the area.
