What comes off

This came off a scalp that gets shampooed every day.

You are not dirty. You were never given the tool. Dermatologists have a name for what sits at the openings under your hair: yellow dots, follicle openings plugged with oil and dead skin. Shampoo has never reached them.

If two of these are you

Built for the man who showers every day and still gets caught.

Flakes on the collar by lunch. Grey shirts only.
Greasy by 4pm after a 7am shower. Day two is a hat day.
The itch you catch yourself doing in a meeting.
More on the pillow and in the drain than last year.
Your barber went quiet at the top of the fade.
Someone you're seeing noticed before you did.
Head & Shoulders worked for a month. Then it came back.
You brush your shoulders off before every photo.

Two or more? This was built for you. Five minutes, every wash. Sixty nights to prove it or you pay nothing.

Why you still have flakes

Shampoo washes hair. Nothing has ever washed your scalp.

3,900 : 0

Count your washes.

Three a week since you were fifteen. Every one cleaned the hair. Your fingers slide over the top, the lather sits on the strands for thirty seconds and goes down the drain. The skin underneath was never touched.

The plug

Oil comes out of thousands of openings all day.

A yeast every man carries eats that oil and leaves behind an acid that irritates the skin. Irritated skin panics and sheds in sheets. Those sheets are your flakes. They are made at the opening, under the hair, where nothing you own has ever cleaned.

5 min

On the skin, not the hair.

84 soft nodes knead the scalp itself, at every opening, under water, with the wash sitting on the skin the whole time. Not thirty seconds on hair. Five minutes on skin. In Tokyo, washing hair and washing the scalp are two different appointments. This is the second one.

Cross-section: fingers glide over hair; the nodes reach the scalp and the plug at each follicle
LEFT: fingers on hair. RIGHT: nodes on skin, at the opening.
Why it always came back

Dandruff shampoo works for three days. Here is why.

Everything in your drawer treated the smoke. Nothing removed the fuel.

Medicated shampooPoisons the yeast for a few days, dries the skin, and the oil comes back double. Markers rise three days after you stop. Flakes are back in three weeks. You were not imagining it.
Growth serums and oilsGood drops, wrong landing zone. On a plugged scalp they sit on top of the plug and feed the yeast that lives on oil.
Fingernails and plastic scratchersThey scrape the surface and inflame it. A barber's hands never scratch. They knead, at the root, under water.
The barberHe sees it every three weeks under bright light, says "buildup," and moves on. He cuts hair. The problem is skin. It was never his job.
Under the hood

Three things your hands can't do.

The questions men actually ask

Will it pull my hair? No.

Soft silicone nodes, not bristles. Part the hair, keep the Dome moving, and it glides. Longer hair: keep it moving and it never tangles.

Does it work on a buzz cut? Better.

Short hair is the easiest scalp to reach. A fade, a crew cut, a shaved side: the nodes sit straight on skin.

Do I still need my dandruff shampoo? Your call.

The Wash goes on the scalp; your shampoo goes on the lengths. Most men retire the medicated bottle inside a month. If a dermatologist put you on one, keep it and use the Dome underneath it: it works better on a clean scalp.

Is it safe wet? It lives in the shower.

IPX7. Rinse it under the tap. Gentle warmth, never above 43°C. Charges on USB-C between sessions.

Same scalp

A clean scalp is where the hair you still have lives.

Your flakes and your thinning are not two problems. They are the same scalp. The oil and yeast that make you flake irritate the roots, and irritated roots let go early. In a six-month study of 150 men with thinning and dandruff, simply clearing the scalp cut shedding by up to 17%. Nobody has shown it regrows anything. It keeps what you've got.

Same barber. Eleven years. First compliment.

Someone at work asked if I switched barbers. Same barber. It was a Tuesday. I wrote it in my notes app.

Bought my first black tee in twelve years.

I only bought grey t-shirts so it wouldn't show. That was my whole system since college. Last week I bought a black one. My wife stopped brushing my shoulder and I noticed the not-noticing.

My barber said "buildup" and wouldn't say more.

So I looked it up and ended up here. Three weeks, same part, same bathroom light. He got to the top of the fade and asked what changed.

The rinse water ran grey the first night.

I have showered twice a day since high school. I stood there staring at the water. Night 14: caught myself looking at my hairline in the gym mirror. Not checking. Just looking.

Counted the drain this morning out of habit.

Then realized I had stopped counting weeks ago. Booked a haircut because I wanted one, not to hide anything.

Annoyingly good. Wish the cord were longer.

Four stars because the charging cable is shorter than I'd like. The itch stopped in week one and my hair stays put a full day longer. Longer cord and it's five.

The Tokyo method
Nao Kurihara, KAMIYU founder

In Tokyo the scalp wash comes with the cut.

Comb, cleanser on the skin, five minutes of kneading under warm water. No man asks for it and no man skips it. America renamed it the head spa and priced it at $150 a session. The steps were never the secret. The access was. I took the finish apart and rebuilt it for a shower.

Questions
How long does one Scalp Wash last?

About eight weeks at three washes a week, because the applicator puts it on the scalp only. Your normal shampoo still does the lengths.

How fast does it ship?

Within 48 hours from our US warehouse. Free on the 90 and 180-day boxes. $5.95 on the Dome alone.

Charge time, weight, noise?

USB-C, about 2 hours to full, roughly a week of sessions per charge. Lighter than a phone. Quieter than an electric toothbrush.

Beard?

Yes, on the lowest setting with the wash. Same skin, same plug.

What is "buildup"?

Oil, dead skin, product and hard-water minerals that harden around each follicle opening. Trichologists call it scale or follicular plugs. We call it the thing your shampoo never reached.

What if it doesn't work on me?

Sixty nights. Email us, we refund every cent and pay the return shipping. Keep the Wash.
