What changes
Colleen B.night 16
My stylist said the word buildup and would not say much more. Less on the pillow by week two. I checked. Checking is what I do.
Whitney A.night 32
Counted the drain catch this morning out of habit. Then realized I had stopped counting weeks ago.
Marisol V.night 9
I ran the Scope over my crown before and after one week. You can see the difference on the screen. Data wins.

Inside the dome
Fingertips slide lather across the top. Eighty-four silicone nodes on counter-rotating heads work pressure and rotation at the root, under water, the way a stylist's hands do at the basin.
Buildup compacts around each follicle like wax around a wick. Gentle heat softens that layer so it lifts and rinses instead of clinging through another wash.
Not shone at your hair from a distance. The light sits against the skin while the nodes work, which is the only place it can reach the follicle.
Fully waterproof, rinses under the tap, charges between sessions. No new routine to remember, no bottle to run out of.
Same three moves, same order, performed on your own head. The difference is that the hour survives the drive home.
Real customers
I photographed my part every Sunday to prove to my dermatologist it was getting worse. These are three Sundays apart. I cancelled the appointment.
The rinse water ran grey the first night. Grey. I sat on the edge of the tub and stared at it, because I have washed my hair every other day for thirty years. That photo is the proof. But night 14 is the part I did not expect: I caught myself checking my part in the elevator mirror. Not for flakes. Just to look.
Counted the drain catch this morning out of habit. Then realized I had stopped counting weeks ago. Booked a haircut yesterday because I wanted one, not to hide anything. That is the whole review.
My colorist stopped mid-foil, picked up a strand and asked what I switched to. I got to say a Japanese word she had never heard. This photo is day-two hair, zero product, right after school drop-off. Day two used to be bun-and-dry-shampoo day.
My stylist said the word buildup and would not say much more. So I looked it up and ended up here. Ten minutes a night where my phone cannot reach me. Less on the pillow by week two. I checked. Checking is what I do.
My daughter gets married in October. I ordered this the night the engagement photos came back, because all I could see was the light hitting my scalp through my part. Night 21: my stylist found new baby hairs along the parting and asked what changed. I am wearing my hair down at the wedding.
I am 61 and I assumed the flakes were just part of getting older, like everything else. My daughter set this up in my shower and wrote the three steps on a sticky note. Week three: I wore navy to church. I have not worn navy since 2019. That is my whole review and my daughter says it is a good one.
Three minutes of kneading while my conditioner sits. The rest fits inside the shower I already take. I have a drawer of things I quit: the derma stamp, the rosemary drops, the $5 brush from TikTok. This one lives on the shower shelf, and apparently I am now the person who says “my ritual” out loud. My sister rolled her eyes. Then she borrowed it.
Four stars because I did not read the method card first and tangled my longer hair the first two nights. Part the hair and keep it moving, then it is effortless. The itch stopped in week one and my blowouts last two days longer.
I am an engineer, so I did not believe the red light part. I looked up the wavelength studies on my phone while my sister was already using hers. Fine: the literature is real. But what sold me was dumber than that. I ran the Scope over my crown before and after one week. You can see the difference on the screen. Data wins.
Feels amazing, but honest note: the first two nights I kept tangling longer strands around the heads until I figured out you part the hair first and keep it moving. The method card actually says that, I just did not read it. Scalp definitely feels cleaner. Roots stay fresh a full day longer.
Someone at work asked if I got a gloss treatment. A gloss treatment. I have not gotten one hair compliment in eleven years at that office. It was a Tuesday. I wrote it in my notes app.
A stranger on the train asked what I use in my hair. A stranger. On the train. I heard myself say “it’s a Japanese thing” like a woman who has her life together. My friend took this photo because she did not believe me about the shine.
Our anniversary dinner. My husband took one picture of me from across the table and sent it to me with three fire emojis. Fourteen years. He has never once photographed my hair. I wore it down and I did not think about it one time all night.
I cancelled my standing blowout appointment. Not to save the money, although that is $260 a month back. My own hair does the thing now. My neighbor took this and I made it my new everything photo.
Run the reset for 60 nights. Then wear the black shirt you stopped wearing and look at your shoulders. If you do not love what you see, one email returns every cent and we pay the return shipping. No forms. No fights.

Before you order
The first rinse tells you: the water runs grey. Itch and grease usually calm inside two weeks. Shedding is a slower system, so give it the full 60 nights, which is exactly what the guarantee covers.
Yes, that is the point. Anti-dandruff shampoo only works if it reaches scalp skin, and it usually rinses off in seconds. Lather, then knead it in with the dome so it finally gets contact time.
IPX7. It lives in the shower, rinses under the tap and charges by USB-C between sessions.
Email hello@trykamiyu.com inside 60 nights and every cent comes back, return shipping included. Less than 1% of customers have ever asked.
