Someone brushed your shoulder without looking up.
You showered that morning. Black tee back in the rotation. A hand in your hair that stays there. Nobody looking at your shoulder. It starts the first time your scalp, not your hair, gets washed, inside the shower you already take.

No hidden subscription. The Dome is yours. Only the Wash renews, only if you ask for it.
Nobody buys this for the flakes. You buy back the couch, the chair and the black shirt.
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.
Get the Scalp Cleaner · $139This is what a hand in your hair finds. Off a scalp you shampoo 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.
Shampoo washes hair. Nothing has ever washed your scalp.
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.
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.
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 on the hair. On the skin. In Tokyo, washing hair and washing the scalp are two different appointments. This is the second one.
Medicated shampoo works for three days. Here is why.
Everything in your drawer treated the smoke. Nothing removed the fuel.
Three things your hands can't do.
Sixty nights. The black shirt, or your money back.
Wear the black shirt again inside sixty nights, or every cent back and we pay the return shipping. Keep the Wash. No forms, no photos, one email.

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 medicated 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.
Waterproof. Rinse it under the tap. Bath-warm, never hot. Charges like a toothbrush between washes.
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 flaking, simply clearing the scalp cut shedding by up to 17%. Nobody has shown it regrows anything. It keeps what you've got.
$150 a session in the chair. $1.54 a day in your shower.

Someone at work asked if I switched barbers. Same barber. It was a Tuesday. I wrote it in my notes app.
Dan K.VERIFIED BUYER · NIGHT 19★★★★★
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.
Marcus T.VERIFIED BUYER · NIGHT 21★★★★★
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.
Andre S.VERIFIED BUYER · NIGHT 14★★★★★
Third date. She did the thing where she runs her fingers through the back, and I did not flinch, because there was nothing to find. Night 14 I caught myself looking at my hairline in the gym mirror. Not checking. Just looking.

Week three: a long video call and I never once reached for my head. Then I realized I had stopped counting the drain weeks ago. Booked a haircut because I wanted one, not to hide anything.
Kyle D.VERIFIED BUYER · NIGHT 22★★★★☆
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.
Same man. Same shirt. Weeks apart.
In Tokyo the scalp wash comes with the cut.
Comb, cleanser on the skin, 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.

Wash auto-ship is optional and you turn it on yourself at checkout. Skip or cancel by text. The Dome never renews.
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 do I use it?
Lather. Put it on your head. Rinse. The comb opens a path through longer hair first and the applicator puts the wash on the skin instead of the strands. Both are in the box.
How fast does it ship?
From our US warehouse, tracked. Free on the 90 and 180-day boxes. $5.95 on the Dome alone.
Charge time, weight, noise?
About 2 hours to full, roughly a week of washes 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.
