Finally, clean your scalp.

★★★★★4.9 average1,213 verified reviews

Roots that stay clean until bedtime. Hair down on day two. The photo where you look like yourself again.

It starts the first time your scalp, not your hair, gets washed. The dome puts the shampoo you already use on the skin, where the grease, the flakes, the itch and the shedding all start.

Ends the flakes at your part
Breaks the wash-then-greasy-by-4pm cycle
Calms the itch you scratch without noticing
A part that stops widening in photos

What it actually costs

Nobody buys a scalp. You buy back the room.

The bed

You showered last night. You still sleep on the far edge of the pillow and wonder if he can smell it. He has not said anything. That is worse.

His hand

In your hair on the couch, then he looks at his fingers. He has not reached for you since.

"Is it wet?"

No. You washed it this morning. It is the third time someone has asked this month.

Walking by

You pass someone in the hallway and wonder if they can smell it. You keep your head down in the elevator.

The photo

You look tired in every picture, older than you are. It is not your face. It is flat, oily roots.

The date

His eyes went to your hairline before your face. There was no second date.

Your sister

Same age, same room. Her hair gets the hands and the compliments. Yours went up in a ponytail again.

The part

Day-two hair, and the part looks wider in every photo. You skipped the party. The dress is still on the hanger.

None of it is your hair. It is the scalp under it, and people read it as how clean you are.That scalp has never once been washed: 3,900 washes on the hair, zero on the skin. Wash the cause, every wash, and the rest goes with it.

If nothing changes

You do not lose it all at once. You lose it a part-width at a time.

The hairs you are losing today started forming under the skin months ago. An oily, flaky, irritated scalp pushes more of them into the shedding phase before their time. This is the clock.

Year one

Hair up every day.

Greasy by four, dry shampoo by five. The ponytail stops being a choice.

Year three

The part is wider in every photo.

You look tired in pictures, older than you are. It is not your face. It is flat, oily roots.

Year five

The follicles let go early.

Five years under an inflamed plug, resting more and growing less. What goes at 45 does not come back at 50.

Your scalp at 35 decides your hair at 55.In a six-month study, clearing the scalp cut shedding by up to 17%. It keeps what you have. It does not grow hair back, and nobody honest will tell you it does. Sudden or patchy shedding belongs with a dermatologist first.

Why Kamiyu exists

Shampoo washes hair. Nothing has ever washed your scalp.

"For twelve years in Japan I washed scalps for a living, and scanned every one onto a screen first. For most people it was the first time they had ever seen their own scalp."

The work worked. Four weeks later they were back with the same scalp, because the hour never survived the drive home. Your fingers move the foam. They never move the plug of oil and dead skin that hardens around each follicle. Kamiyu is that hour, rebuilt for your shower.

Nao Kurihara · founder, Kamiyu

kamiyu · noun · Japanese. Kami, hair. Yu, bath. The Japanese habit of washing the scalp itself, not just the hair. Tokyo salons have done it for decades. American salons charge $150 a session for it. Now it runs in your shower.

Inside the dome

Three things your fingers cannot do.

Same shampoo. Same shower. The only thing that changes is how far down it gets.

84 kneading nodes

A therapist's fingers, counter-rotating. They knead the plug loose at the skin. They never scrape.

Onsen warmth

Bath-warm, never hot. It softens hardened buildup first, so it lifts instead of smearing.

Red light, 630 to 680nm

The band hair-density trials use, delivered at the root under running water, on the follicles the nodes just cleared.

IPX7 waterproof · USB-C, cordless · safe on fine, thinning and colored hair

What to expect

Sixty nights. This is the order it happens in.

Night 1

The rinse water runs grey.

Most people watch the first rinse. That is years of buildup leaving, not the shampoo.

Night 10

The next layer reaches the surface.

A one-off treatment quits here. This one runs inside every wash you already take.

Night 30

The itch goes quiet. Grease slows down.

Wash days start stretching. Hair down on day two stops being a gamble.

Night 60

Check your shoulders in the black top.

Shedding is the slow system. Give it the full sixty, then look. That is the guarantee.

Why nothing has worked

You already tried. Here is why each one failed.

Medicated shampoo

Strips the surface, misses the plug, and dries the scalp until it doubles its oil in defense.

Growth serums

Good actives, wrong landing zone. On a plugged scalp your serum sits on the wax, not the wick. Keep the bottle. It was never the problem.

Fingernails and plastic brushes

They scratch the surface and inflame the skin. A head spa therapist never scratches. They knead.

The $150 salon

It genuinely works. Once. The plug rebuilds inside two weeks, and the front desk books your next visit before you reach the door.

Every one of these is still in the cupboard. Not one of them ever reached the skin.

The Black Shirt Guarantee

60 nightsfrom the day it arrives

Wear the black top again, or every cent back.

Sixty nights is how long it takes to clear a plug that took years to build. If the shoulders are not clean, send it all back for every cent. No forms. No fights. One email does it, and we pay the return label. Less than 1% of our customers have ever asked.

Questions

Everything people ask before they add it to the cart.

What makes the Kamiyu different?

Three things working at once, which is what makes it a treatment and not a wash: 84 counter-rotating nodes that knead the way a therapist kneads, onsen warmth that softens hardened buildup so it lifts instead of smearing, and 630 to 680nm red light delivered at the scalp itself. That is the $150 session, minus the chair.

Will it work on my scalp?

Flakes, grease by 4pm, the itch, more hair in the drain: they look like four problems but they start in the same place, the buildup at the root. That is the surface Kamiyu clears, whichever mix of the four you have. One honest exception: if you have psoriasis, eczema, open sores, or you are under a dermatologist's care for a scalp condition, check with them first. If your shedding is sudden or patchy, see a dermatologist first and bring the photos of your part.

Does it work with my medicated shampoo?

Yes. That is the point. A medicated shampoo only works if it reaches scalp skin, and it usually rinses off in seconds. Lather, then knead it in with Kamiyu. Zinc, ketoconazole, salicylic acid: whatever your shampoo uses, it finally gets contact time.

How fast will I notice something?

The first flush shows you immediately: the rinse water tells the story. Itch and grease usually calm within the first two weeks. Shedding is a slower system, give it the full 60 nights, which is exactly what the guarantee covers.

Long, curly, thin, or colored hair?

The nodes knead at the skin and do not pull; on thinning hair they loosen what is holding the hair back. The Scalp Wash is silicone-free, so condition your lengths as you always do. Nothing in the system strips color. For protective styles, use the applicator along exposed partings and the dome on wash days.

Do I need a special shampoo?

The Dome will work whatever shampoo you own into the scalp, so your next wash is covered either way. But regular shampoo is built for hair: it coats the lengths and leaves the film that hardens back into the plug. The Scalp Wash is built for the skin, so it keeps the follicle open once the Dome has cleared it. That is why the 3 and 6 month Resets carry the supply.

Is it waterproof?

IPX7. It lives in the shower, under running water. Rinse it under the tap when you rinse yourself. Do not leave it soaking in the bath. It charges by USB-C between washes.

How does the Black Shirt Guarantee work?

Run the reset for 60 nights, counted from the day yours arrives. Then wear the black top you stopped wearing and look at your shoulders. If you do not love what you see, one email to hello@trykamiyu.com refunds every cent, and we pay the return shipping. No forms. No fights.
