Benefits
keyboard_arrow_downLands on the scalp, not the strand — the silicone brush parts the hair so the formula goes where the root actually is.
Designed to get below the surface. Reedle Shot micro-spicules open temporary micro-channels so the actives have a way down instead of sitting on top.
Roots that look fuller and denser at the part line, over 8 to 16 weeks.
Less coming away in the brush usually the first thing women notice.
A calmer scalp: less itch, less tightness, no white flakes after drying.
Cools on contact, absorbs clean. Nothing on the pillow, no flat greasy roots in the morning.
Two minutes a night. No pills, no device, no appointment, no subscription.
How It Works ?
keyboard_arrow_downYour scalp's whole job is keeping things out. That's why the serums you've tried slid off the surface they were landing on hair, which is dead keratin, or sitting on a barrier built to block them. It wasn't your discipline. It was the door.
Klyver works in three steps, in the right order:
1. Part. The silicone brush pushes the hair aside and lays the formula down on the scalp itself. One pass per part line.
2. Path. Reedle Shot spicules hollow micro-structures from marine sponge silica — are designed to open temporary micro-channels in the outermost layer of the scalp. They close again on their own. No metal needle, no roller, no blood.
3. Payload. PDRN travels down that route, supported by caffeine, Korean ginseng, biotin, peptides, centella and hyaluronic acid.
The right place, the right route, the right molecule. And because you part your hair in the same spot every night to apply it, you finally have something to compare against instead of guessing under a different light every day.
Ingredients
keyboard_arrow_downPDRN (Sodium DNA) — the salmon-derived DNA fragment at the centre of Korea's scalp-clinic routines. It started in wound and burn repair, not beauty. Here it works on the scalp itself: calmer, better-conditioned skin is a better home for fuller-looking roots. Topical PDRN is not the same as a clinic injection, and we won't pretend otherwise.
Reedle Shot Spicules — microscopic marine sponge silica, designed to open temporary micro-channels in the surface layer so the actives aren't left sitting on top.
Caffeine — the cooling hit you feel in the first ten seconds. Helps energise the scalp and supports roots that look less flat by morning.
Korean Ginseng — a botanical Korean scalp care has leaned on for generations, for scalp comfort and stronger-looking hair.
Biotin + Peptides — biotin, but applied where you see the problem instead of diluted through the bloodstream. The peptides are conditioning agents: hair looks thicker and feels less fragile in the hand.
Centella + Hyaluronic Acid — cica calms irritated, tight scalp skin; hyaluronic acid holds water where it's applied. Together, why Klyver can be used nightly without itch or flakes.

Our Guarantee
keyboard_arrow_downThe 60-Day Root Guarantee. You've already spent money on things that did nothing. We're not asking you to do that again on faith.
Use Klyver every night for 60 days. If your brush isn't cleaner and your part line doesn't look fuller, email us and we'll refund you. Bottles can be open and half-empty — that's the whole point. You can't judge this in three weeks, so we've built the window in.
No subscription. No auto-renewal. No re-stocking fee. The only guaranteed failure in this category is quitting early, and that risk is ours, not yours.
I cried in the shower more times than I'll admit, watching my hair go down the drain. Three serums, two years of supplements, a dermaroller I used four times. I'd given up. Klyver was the first thing that explained why none of it ever worked — it never got down there. Two minutes at night and I finally feel like I'm doing something real.
Four months after my daughter was born I was pulling handfuls out and nobody warned me. I felt like a stranger in the mirror. The brush was the moment it clicked — it parts the hair and the serum lands on my scalp, not smeared down the lengths. Nothing runs onto my forehead. I look forward to it now. It's two minutes that are just mine.
My scalp was oily and itchy by day two and every serum I tried made it worse — flat roots, flakes, that unwashed look. Klyver goes on cool and dries down clean. I wore my hair up to my son's graduation for the first time in three years and didn't think about it once all day. That's what it gave me back.
The exhausting part was never the hair. It was checking my part under every single light and getting a different answer each time. Parting it in the same spot every night means I finally know where I stand instead of guessing. Less coming away in the brush, and my shoulders came down about two inches. I didn't know how much I'd been carrying.
For years I was told it was normal and to be patient. I stopped bringing it up because I was tired of being dismissed. Klyver was the first explanation that made sense of the whole mess — the products were landing on the hair, not the scalp. Week nine, my brush is noticeably cleaner and I stopped apologising for caring about this.
I almost didn't order. I'd promised myself no more subscriptions, no more four pills a day, no more money thrown at hope. This is two minutes before bed and nothing auto-renews. The cooling feeling is what kept me going the first few weeks — and my husband noticed my roots before I said a word. I sat down and cried.
Most serums stop at the surface. Here's what Klyver is designed to do differently — and why the place it lands changes everything.
Your scalp's whole job is keeping things out. That's why the serums you've tried slid right off the surface. Klyver's silicone brush parts the hair and puts the formula on the scalp itself not on the strand, where nothing living happens.
The same regenerative molecule behind premium Korean scalp treatments, in a format you apply yourself. Reedle Shot micro-spicules are designed to open temporary channels in the surface layer, so the actives have a way down instead of sitting on top.
The brush tip goes to your exact problem spots part line, temples, crown. Not your whole head. Right where you keep checking. Two minutes at night, no rinse, no flakes, no flat roots in the morning.
The salmon-derived DNA fragment at the centre of Korea's scalp-clinic routines. It wasn't invented for beauty at all — it started in wound repair and burn recovery, and Korea noticed what it did to normal skin along the way.
In Klyver it works on the scalp itself, not the hair. A calmer, better-conditioned scalp is simply a better home for roots that look fuller. Worth being straight with you: topical PDRN is not the same thing as a clinic injection, and we won't pretend otherwise.
The ingredient behind the cooling hit you feel in the first ten seconds. It's also the one thing you'll notice on night one, long before anything else has had time to happen.
On the scalp it helps energise the surface and support roots that look healthier and less flat by morning — no greasy film, no second-day residue at the part line.
A botanical Korean scalp care has leaned on for generations, long before any of this reached a lab. It's included for scalp comfort and for hair that looks stronger and better conditioned.
No magic claimed here. It earns its place because it pairs well with everything else in the formula and because it's been used on scalps for a very long time without drama.
Micro-spicules drawn from marine sponge silica — hollow, microscopic, and the reason Klyver isn't just another serum sitting on your skin. They're designed to open temporary micro-channels in the outermost layer of the scalp so the actives have somewhere to go.
The channels are shallow and they close again on their own. No metal needle, no roller, no blood, no device, no appointment. If you've ever put a dermaroller down after four uses, this is the part that replaces it.
Biotin is the name you already know from the supplement aisle — the difference here is where it goes. Swallowed, it's diluted through the bloodstream and sent everywhere in your body at once. Applied on a parted scalp, it stays where you actually see the problem.
The peptides are short chains of amino acids, the same building blocks your hair is made from. In cosmetic use they're conditioning agents: they help hair look thicker, feel less fragile in the hand, and hold up better to being brushed, tied back and slept on.
Centella asiatica — cica — is the Korean skincare staple for skin that's irritated, tight or reactive. Your scalp is skin, and it's usually the most neglected skin you own.
Hyaluronic acid holds water where it's applied, which is what keeps a leave-on formula from leaving you dry or flaky by morning. Together they're the reason Klyver can be used nightly without the itch, tightness and white dust that made you quit the last one.
Klyver is a cosmetic product. Ingredient descriptions refer to cosmetic function only and are not medical claims. Spicules create temporary micro-channels in the outermost layer of the scalp.
You've been let down before. Here are the straight answers — including the ones most brands leave out.
You're right to ask, and honestly — you were right about the others too. They didn't fail because you picked badly or gave up too soon. They failed because they never got past the surface of your scalp.
Klyver is built around that one problem. The brush parts the hair so the formula lands on the scalp instead of the strand, and the spicules are designed to open temporary micro-channels so the actives have a way down. Different place, different route. That's the whole difference.
The cooling feeling is immediate — night one. Everything else takes time, and we'd rather say so now than lose you at week three.
Give it 8 to 16 weeks. The first change most women notice isn't in the mirror, it's in the brush: less coming away. That usually shows up before anything else does.
This is the fear that stops most women from starting anything new, so here it is plainly: some scalp routines are followed by a short period of increased shedding in the first few weeks. It's the single most common reason people quit at week two or three.
If it happens, it isn't a sign the product is making things worse — but you're the one who decides what you're comfortable with. Know it's possible before you start, not after, and use the full window before you judge.
No — and this is the part you can check for yourself within a week, without waiting for anything. The formula goes on cool, absorbs clean and leaves nothing on the pillow.
The one thing that causes greasiness is overdoing it. One pass per part line with the brush, three to five drops with the ampoule. More is not better here, it's just heavier.
There's no subscription. Nothing auto-renews, nothing gets charged to your card without you clicking. You buy the kit, and that's the end of the transaction.
Klyver is a protocol with a beginning and an end — two minutes a night across the 8 to 16 week window, not four pills a day for the rest of your life. What you do after that window is entirely your call.
No. There's no metal needle, no roller, no device and no appointment. The spicules are microscopic silica structures from marine sponge, designed to open temporary channels in the outermost layer of the scalp — the layer that's already shedding on its own.
Most women describe a light cooling or tingling sensation, nothing more. It's the same technology that went viral on faces in 2024, adapted for the scalp and applied with a brush instead of your hands.
