What To Expect With Consistent Use Of Our #1 Selling PDRN Serum
-
WEEK 1
Shedding slows
Fewer hairs in your brush, fewer in the drain. Here’s why: after 40, your estrogen drops by 95%, and estrogen was the signal that told each hair to keep growing. PDRN sends that signal again, so the hairs that were about to let go hold on.
-
MONTH 1
Baby hairs along your part
Short, all one length, standing straight up: new growth. They show up first where you thinned first, your part and temples, the hairs that needed estrogen most. Not dead, just asleep.
-
DAY 60
Your call
Look at your part from above, in daylight. If you don’t see a difference, one email and you get every penny back.
-
MONTH 3
Unrecognizable
Fuller and thicker, more volume than you’ve had since your 30s. Your hair tie wraps twice again. Your part narrows.
In Her Own Words
-
“Biotin didn’t fix it. Neither did the shampoo. Two months in, my hairdresser asked what I’d changed.”
Linda M., 58
-
“Blood work normal, part still widening. 90 days later, my hair tie wraps twice again.”
Karen T., 47
-
“Eight months of Nutrafol, four pills a day. Nothing. Sixty seconds of this a day, and by week 2 there was less hair in my brush than I’d seen in years.”
Donna R., 61
-
“I counted. Forty-something hairs in the drain every morning. Now I stop counting at ten.”
Patricia H., 55
-
“I thought 66 was too late. Little hairs along my part at week 6. My daughter saw them before I did.”
Joan K., 66
-
“I was sure I’d quit like I quit everything else. Sixty seconds a day. That’s it. That’s why it’s still in my bathroom.”
Susan B., 52

Fewer than 3% of our customers ever ask.
This started in a clinic in Seoul.
My mother stopped tying her hair up the year she turned 52. There was nothing in her hand. Then she stopped wearing it down, because you could see her scalp. Her doctor ran the blood work. Everything was normal. “It’s your age.”
Two years later I was in Seoul for work, sitting in a dermatology clinic, watching women my mother’s age pay up to $1,000 a session to have PDRN injected into their scalps. Not for wrinkles. For their part.
I asked the doctor the obvious question. Why does nobody in America know about this? Her answer: because it needs a needle, and a clinic, and a doctor who’s read the Korean studies. Then she said the thing this company is built on. There’s a way to get PDRN into the follicle without the needle. Spicules.
Here’s what I learned over the next two years. After 40, estrogen drops by 95%. Estrogen was the signal that told each hair to keep growing. At 25, a hair stayed on your head for up to 7 years. Now it falls after about one. That’s the drain, the mirror, the part that keeps getting wider.
And that’s why nothing my mother tried worked. Her hair is like a lamp. Estrogen was the switch. After 40, it got turned off. She screwed in every bulb she could find: vitamins, oils, DHT blockers. The lamp stays dark until the switch goes back on.
PDRN is the ingredient that flips that switch back on. In a published study, women with thinning hair got 17.9% more hair and 13.5% thicker hair after 12 weekly PDRN sessions1. Our Spicule Complex carries it down to the follicle, where it gets to work. No needle. No clinic. 60 seconds with the brush, once a day.
My mother’s part closed up. That’s the whole reason NAYA exists.
Here’s my promise. If you don’t see a difference in your part by day 60, one email and you get every penny back. No forms, no questions.
I’m not asking you to believe me. You’ve been asked to believe people before. I’m asking you to give it 60 days and let your own drain tell you.

How NAYA Came To Exist
Two years of building it, and the three things that had to be true.
-
The switch nobody was flipping
Everything on the shelf treats hair loss in general. Nothing was built for the one thing that changes after 40: the signal that tells your hair to keep growing goes quiet. So vitamins feed hair that isn’t underfed, oils sit on top, and DHT blockers block a hormone that was never your problem. None of them touch the switch, because none of them were ever aimed at it.
-
The problem we didn’t expect
You can have exactly the right ingredient and still get nothing. Your scalp is skin, and skin is built to keep things out. That’s why most serums just dry on top. Seoul clinics solve it with a needle. We solved it with spicules: microscopic mineral crystals, finer than a hair, that slip into the top layer of your scalp, carry the PDRN down to the follicle, then dissolve. We call it Reach & Grow. Reach: the spicules carry it down. Grow: PDRN sends your follicles the same GROW signal they got at 25. Not a weaker version. Not a hormone.
-
The proof we stand on
PDRN isn’t a trend we made up. It started as a prescription medicine in Italy, then moved into Seoul clinics, where it’s been used on thinning hair since 2014. In a published study, women with thinning hair treated with PDRN alone got 17.9% more hair and 13.5% thicker hair after 12 weekly sessions1. Then we tested the tube: 68 women over 40, every day, at home. 96% saw less shedding by week 2. 85% saw new baby hairs by week 6. 92% loved that it wasn’t oily or messy2.

“Every client over 50 asks me about her hair, and she’s already taking biotin. I’ll say it plainly: this isn’t a nutrition problem. No supplement flips a switch.”
Here’s Why What You’ve Tried Hasn’t Worked
After 40, estrogen drops and each hair falls out sooner3. Everything below is a bulb. Your switch is still off.
-
Biotin & hair vitamins
The claim: Feed your hair the vitamins it’s missing and it grows back stronger.
The truth: Biotin only does anything if you’re low on it, and in women eating a normal diet, that’s almost never. When researchers tested biotin against a dummy pill, both groups grew the same amount of hair4. Your hair isn’t finishing early because it’s underfed. It’s finishing early because the signal stopped. A vitamin can’t send a signal.

Rosemary and other oils
The claim: Massage the oil in and it wakes up your follicles.
The truth: Your scalp’s outer layer is built to keep things out. Most of what you put on it never gets past the opening at the top of the follicle5. So the oil sits on your hair, your hair looks greasy, and the follicle at the bottom never hears from it. Shine on the surface is not a sign that anything reached the follicle.

DHT blockers and hair supplements
The claim: Block DHT and your hair stops thinning.
The truth: DHT blockers were built for men’s pattern loss. What changes after 40 in women is estrogen, the signal that keeps a hair growing3. Block all the DHT you want, the switch is still off. And a major review found there isn’t enough evidence to recommend the vitamins and minerals most hair supplements are built on6.

Minoxidil
The claim: The one FDA-approved drug for women’s hair loss.
The truth: It shortens the resting phase, so the next hair starts sooner. That’s why it makes you shed harder for about two months. It’s greasy, it’s twice a day, and the biggest trial of it in women stopped at age 497. Not one of them was over 49.

Frequently Asked Questions
My blood work came back normal. So is it really this?
Yes, and that’s the point. Normal blood work means it isn’t your iron or your thyroid. After 40, estrogen drops by 95%, and no blood panel flags that as a problem. Your hair does.
Could my hair loss just be stress?
Stress shedding starts, peaks and stops within a few months. A part that’s been widening for a year or more is the signal, not stress.
I’m on HRT. Will that fix it?
HRT fixed your hot flashes. It didn’t fix your part, or you wouldn’t be here. PDRN sends the GROW signal straight to the follicle. You can use both: ask your doctor if you’re unsure.
Is it too late if my hair loss started years ago?
Your follicles weren’t dead, just dormant, waiting for the signal. The ones that relied on estrogen the most respond before the others. Give it 60 days and let your part answer.
How does this compare to minoxidil?
Minoxidil restarts hairs sooner, twice a day, for life, with two months of extra shedding to begin. PDRN sends the growth signal, 60 seconds a day, no hormone, no drug. We never tested them against each other.
Will I shed more when I start?
No. Shedding usually slows within the week. If you used to shed in the shower every day, compare week to week, not shower to shower.
Can PDRN really get through my scalp?
On its own, no: your scalp is skin, and skin keeps things out. That’s what the Spicule Complex is for. The spicules carry the PDRN down to the follicle, then dissolve. No needle.
What are spicules? Does it hurt?
Microscopic mineral crystals, finer than a hair. No needle. You may feel a light tingle for a minute. No pain, no redness, no clinic.
Is it greasy? Will it mess up my hair?
No greasy roots. It’s a light gel that dries on your scalp in minutes. Style as usual.
Does it work on gray hair?
Yes. The GROW signal has nothing to do with color. The follicles under gray hair respond the same way.
How long until I see results?
Shedding slows in about a week. Baby hairs along your part at about a month. Fuller, thicker hair by month 3. Results vary.
How do I know it’s working before three months?
Count the drain. Fewer hairs by week 2 is the signal that the switch is back on. Then watch your part at month 1.
Will the shedding come back if I stop?
The signal is PDRN. Stop it and, over months, your hair goes back to doing what it did before. Most women keep going because 60 seconds is easier than the drain.
Is this backed by real clinical data?
PDRN is backed by a published study in women with thinning hair: 17.9% more hair, 13.5% thicker strands after 12 weeks1. Our 68-woman home study is published in full below2.
Where is it made?
Formulated and made in Korea, home of PDRN. Ships within 1-2 business days, delivered in 5-9 business days.
