The #1 scalp cleaning of 2026 · Tokyo method, your shower

Your shampoo washes your hair. Nothing has ever washed your scalp.

For womenWhite dome

For menBlack dome

Same dome. Same shower. Two colours.

In Tokyo, washing hair and washing the scalp are two different appointments. The KAMIYU Dome is the second one: warmth, 84 kneading nodes and red light, under water, every wash. The flakes stop. The 4pm grease stops. The drain empties.

The black is the shirt

Nothing on the shoulders. That is the whole test.

Flakes, grease, itch and shedding are four symptoms of one thing: a scalp that has never been cleaned under the hair. These are customer photos as submitted. Phone cameras, bathroom light, no retouching.

How it works

Three things happen at once. That is the whole trick.

Warmth melts it

Sebum is semi-solid at room temperature. Warm it and it turns to liquid. This is the step the salon does with a steam towel. Nothing lifts until it softens.

84 nodes knead it out

Counter-rotating heads work the way a Tokyo therapist works: under water, at the root, on the skin. Contact time is the part your shampoo never had.

Red light feeds the follicle

630 to 680 nanometre light is the most studied thing you can point at a hair follicle. It only reaches skin once the buildup is off it. Clean first, then feed.

The Scalp Wash

The Dome opens it. The Wash keeps it open.

Regular shampoo is built for hair. It leaves silicone and conditioning polymers behind, and by night ten the follicle is coated again. The Scalp Wash is built for skin.

Pure tea tree. Rinses to nothing.
No silicones, no sulfates, no synthetic fragrance.
One bottle a month, in every Reset.

A stranger on the train asked me

She asked what I use in my hair. Nobody has ever asked me that. Six weeks ago I was parting it in the car to check how bad the flakes were before a meeting.

My barber said it out loud

He asked what I changed. He has been cutting my hair for nine years and he actually stopped and looked. The buildup he used to scrape off is gone.

I wore navy to church

I am 61 and I stopped wearing dark colours a long time ago without ever deciding to. Last Sunday I did not check my shoulders once.

Questions

Before you decide.

Do I still use my own shampoo?

You can. The Dome does the cleaning. But regular shampoo is built for hair and leaves silicone and conditioning polymers on the skin, so the follicle coats over again around night ten. The Scalp Wash is built for skin and rinses to nothing, which is why one bottle a month comes in every Reset.

How fast will I see something?

Night one, most people see it in the rinse water: grey, then clear. The part line and the shoulders take two to three weeks. The shedding in the drain is the slowest, usually week four to six. Sixty nights covers all of it, which is why the guarantee is sixty nights.

Is it safe for coloured, thin or fine hair?

Yes. The Dome works on the scalp, not the hair. The nodes are soft silicone, the warmth is the temperature of a warm shower, and the red light is the same 630 to 680 nanometre range used in clinical scalp devices. The shower you already take is the whole protocol.

What if it does not work for me?

Sixty nights, then one email. Every cent back and we pay the return shipping. Less than one percent of customers have ever asked.
